What is GEL Battery

Gel batteries are called gel because they use silica (or sand) to turn the acid inside the battery into a thick liquid. This liquid does make it spill-proof, like our AGM batteries, but the gel is fragile, and can be easily burned if used in high amperage situations. If you want to know the specifications and prices of GEL Battery, please contact us!

Advantage of GEL Battery

Safety
Gel batteries are distinguished by a high level of safety. The battery acid has been transformed into a gel that cannot leak. This eliminates the risk of acid spilling if the battery is tipped over or broken. The battery also produces virtually no dangerous gasses, which allows the batteries to be safely used in small spaces.

Resistant Against Vibrations and Shocks
Gel cells are also particularly resistant to vibrations and shocks, meaning they can be used on a boat engine or in an agricultural vehicle without any problem. Because the batteries are vibration-resistant, the risk of damage during transport of the batteries is also very small.

Long Lifespan
Gel batteries have a very long service life, which means they are ideal if you need the battery for a long time. They can last up to 4 times longer than conventional batteries: especially in hot climates or with regular use in places where the battery capacity is often heavily discharged (e.g. in solar installations or wind turbines), the endurance is striking.

Not Affected By Temperature
De temperatuur van gel accu's is ongeveer 10 graden Celsius lager dan andere soorten batterijen, wat betekent dat ze kunnen worden gebruikt in extreme omstandigheden en warme klimaten.
Performance at different discharge levels
Gel batteries perform great at different discharge levels. This means, among other things, that they are ideal for solar energy systems or wind turbines. The battery can be deeply discharged on a regular basis and still remain in good condition. On the other hand, the battery can also be charged and stored for a long time without any problem. This is due to the gel added to the electrolyte.

Maintenance Free
Because the batteries are comprised of gel instead of liquid, there is little to no maintenance to keep the battery working properly.
No Leaks
Even though wet cell batteries are sealed in a plastic encasement there is still the chance that it will leak. Gel batteries are also sealed but with a valve that removes excess pressure. This means that between the gel substance and the removal of pressure, there is nowhere for the mixture to go.

Install Them Anywhere
Gel batteries have the advantage of being able to be used in virtually any position, because they don't leak and are generally maintenance free. This greatly increases the number of applications gel batteries can be used for.

Minimal Risk
When damage occurs to a traditional lead-acid battery you are faced with a massive and dangerous clean up (not to mention the impact on anything the battery acid may come into contact with during the process). Gel batteries will not leak out if the casing becomes damaged, so there is a reduced risk of harm coming to the equipment and clean up hazards.

No Fumes
Because these batteries are comprised of a gel substance there are minimal fumes created as a result of use. This means that there is a reduced need for ventilation which increases the potential applications gel batteries can be used for, as well as making them easier to charge anywhere.

Resistant To Discharge Death
When using a wet cell battery it's important that you don't allow the battery to discharge too much. Otherwise, it will never recharge. Gel cell batteries aren't that way. They are deep cycle batteries which means that they can discharge more and still be recharged like new.

Longer Lifespan in Extreme Weather
Gel cell electrolyte prevent electrolyte being evaporated in high temperature or being frozen in low temperature, which keep battery in high performance in extreme weather. Extremely safe When excessive gas production by inappropriate charging occurs, safety valves will automatically emit the gas to prevent battery cracked.

All Round Comparison About Gel Battery Vs Lead Acid

What is a Gel Battery And Lead Acid?
Before comparing gel battery vs lead acid, let's first clarify their concept. A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. Gel battery is a kind of gel electro-hydraulic battery, which belongs to the development category of lead-acid battery. It is an improvement of ordinary lead-acid battery with liquid electrolyte, and gel electrolyte is used instead of sulfuric acid electrolyte. The easiest way is to add a gelling agent to sulfuric acid to make the electro-hydraulic sulfuric acid into a colloid.
Gel batteries have a gel electrolyte instead of liquid electrolytes like in conventional lead-acid and other types of rechargeable batteries, except for solid-state lithium-ion battery and lipo-battery.The gel electrolyte can form a solid protective layer on the electrode plate to prevent the electrode plate from being corroded. At the same time, it also reduces the plate bending phenomenon and the short circuit of the plate when the battery is used under heavy load, and better prevents the active material of the plate from softening and falling off, and has good physical and chemical protection.
Can I Replace Gel Batteries With Lithium?
The best temperature environment for lead-acid batteries is about 20-25 degrees Celsius. When the temperature drops, the activity of various substances in the lead-acid battery will decrease, the resistance will increase, the battery capacity will become smaller, the charging effect will decrease, and the power storage capacity will decrease, affecting the normal operation of the battery. When it comes to the temperature performance of gel battery vs lead acid, gel battery seems to be better.
The gel battery has strong cold resistance, and its working efficiency is much higher than that of ordinary basic lead-acid batteries at -15 °C, and its thermal insulation performance is excellent. Nevertheless, the low temperature performance of gel batteries is still inferior to that of lithium batteries. The ternary lithium battery has excellent low temperature performance, and can maintain about 70% to 80% of the normal battery capacity at -20 °C. So, if you want your devices to last longer than just one season without needing maintenance every few months, then buy yourself some lithium-ion batteries today!
Does Gel Batteries Need a Special Charger
You should not wait until the gel battery is used up to recharge it, and it should be charged in time after discharge. You will need a special charger for your gel cell battery. The charger is different from the lead-acid battery charger and it uses a pulse-charging method to charge your batteries. This means that instead of charging in one go, as you do with most types of batteries, the gel cell battery is charged at intervals during its lifespan. The principle of gel battery charging is as follows:
Pulse Charging: To keep your device running smoothly while you are away from home or work, there needs to be enough power stored in your vehicle's main electrical system so that everything works properly when needed (including lights). A pulse generator sends pulses through lines connecting each component, so not only does this help prevent problems, but also makes sure everything stays connected correctly throughout use!
Do Gel Batteries Need Maintenance?
Maintenance is also an important aspect of the comparison between gel battery vs lead acid. Gel batteries do not require regular maintenance. No acid is added to the electrolyte, and there are no water levels to check or maintain. For that reason, it's a good idea to check your battery for cracks or leaks before using it for an extended period of time.
Are Lead-Acid and Gel Batteries The Same?
Lead-acid and gel batteries are not the same, so there is a comparative analysis between gel battery vs lead acid. Gel batteries are sealed, which means that they are maintenance-free. When comparing gel battery vs lead acid, gel battery is better in many ways. The energy and power of the gel battery are more than 20% larger than that of the conventional lead-acid battery, the lifespan is generally about twice as long as that of the conventional lead-acid battery.
In addition, the high temperature and low temperature characteristics of the gel battery are also better than the ordinary lead-acid battery. However, the downside is that these types of batteries are more expensive than their counterparts because their production technology is difficult and the cost is high. In contrast, lithium batteries with better performance in all aspects may be a better choice, and their average daily cost is much lower than the former two.
Can a lead acid battery charger charge a gel battery?
Yes, you can use a lead acid battery charger on a gel battery. To charge your gel cell battery, connect it to the charger, and open the clamps that connect it to your device's electrical system. Once you have connected your gel cell battery, plug in the charger according to its manufacturer's directions (usually around 2 amps). The most common way of charging them is with an automatic voltage regulator that adjusts voltage based on demand by monitoring the current draw from each cell individually. This type of charger will let you set specific voltages for each phase of charging in order to prevent them from overcharging.
How Long Do Gel Batteries Last?
Gel batteries have a longer lifespan and cycle life than lead acid batteries. The average lifespan of a gel cell is 8 years when used under normal conditions, while lead-acid cells typically have an average life span of 4-5 years. As mentioned above, the cycle life of lithium-ion batteries can reach 4000 times, which also means that it can be used for 10 years (4000/365≈10.96) under the premise of normal charging and discharging once a day, which is significantly longer than the previous two.
Conclusion
In general, gel batteries belong to a development classification of lead-acid batteries, but their performance in cycle life, applicable working environment and safety are better than ordinary lead-acid batteries with liquid electrolytes. Although gel batteries have many advantages, they are still not as environmentally friendly as lithium batteries, and are inferior to lithium batteries in many other aspects such as service life and high and low temperature adaptability. Therefore, the best lithium batteries will still be your optimal choice.

Component of Gel Battery

Separator
Now we use glass fibre Absorbed Glass Mat and absorbed plenty Gel and acid electrolye with good tensile property.Compared to PE or PVC separator, AGM separator with better resilience and small internal resistance. Through the chemical lab testing, after long time boiled in H2So4 electrolyte with high temperatures, the AGM separator still in good condition.

ABS Plastic containers
The ABS has better mechanical property than traditonal PP case.It has low temperature impact resistance and not easy to deformation.The contractibility rate of ABS is at 0.4-0.9% but PP at 1.6%-2%. This can ensure the ABS container not easy loss water and avoid dry the battery.

Gel Electrolyte
Our SiO2 GEL is original made in Germany. Use vacuum Gel filling machine , the Gel electrolyte permeate in to AGM separator homogeneous. Compare to using the PP or PVC separtor, the Gel can be even distribute in the separtor instead of staying in the bottom area. It can improve battery chemical action and increase battery discharge efficiency.

Frequently Asked Questions

Q: Which is better gel or lithium battery?

A: Efficiency – lithium-ion or lithium PO4 batteries are more efficient than gel batteries and have a higher number of cycles based on 80% depth of discharge. They also have a built-in circuit braker and a battery management system.

Q: What's better AGM or gel battery?

A: Gel batteries are less sensitive to temperature than AGM batteries, and their performance is not as affected by extreme temperatures. Gel batteries are less likely to leak than AGM batteries, as the electrolyte is better sealed. Gel batteries typically come with a more extended warranty than AGM batteries.

Q: What is the lifespan of a gel battery?

A: Gel batteries have a slightly longer lifespan compared to flooded batteries, lasting about 10 years on average. They can typically offer between 500 and 5,000 cycles depending on the depth of discharge and quality of the battery.

Q: Is 100ah lithium better than 200Ah gel?

A: 100ah Lithium or lifepo4 will actually give twice as much usable capacity as a 200Ah gel or agm. Lithium keeps its voltage constant right down to empty. It weighs less than half as well. Lifepo4 can charge faster and at a constant rate thanks to a BMS built in.

Q: Do gel batteries last longer?

A: The energy and power of the gel battery are more than 20% larger than that of the conventional lead-acid battery, the lifespan is generally about twice as long as that of the conventional lead-acid battery.

Q: Which is better deep cycle or gel battery?

A: AGM Batteries have a lower internal resistance that allows for much faster charging and better performance under heavy load conditions. AGM Batteries will most likely also perform better than GEL in colder operating conditions, and AGM is often less expensive as an option for getting reliable power.

Q: Are gel batteries good for solar?

A: Gel batteries, like AGM batteries, can be particularly useful for small, off-grid solar systems. For example, a remote cabin with low energy demand and a small system on the roof may be the perfect candidate for a gel or AGM battery bank.

Q: Why do gel batteries fail?

A: For GEL batteries, it is necessary to avoid situations where the battery is left uncharged for a long time, discharge current exceeds the maximum allowed current, and discharge depth exceeds 50%, as these may cause the battery to lose the ability to maintain its charge.

Q: Can I charge a gel battery with a normal charger?

A: Gels have a lower internal resistance. Thus they draw more current (and power) than a wet lead-acid battery and will overheatbon a standard charger.

Q: How many solar panels do I need to charge a 100Ah GEL battery?

A: Charging your battery at 12 volts and 20 amps will take five hours to charge a 100 amp hour battery. By multiplying 20 amps by 12 volts, 240 watts is how big of a panel you would need, so we'd recommend using a 300w solar panel or 3 100 watt solar panels.

Q: What kills a gel battery?

A: Sealed lead-acid (SLA) and gel batteries, for example, are particularly susceptible to overcharging damage because any lost water cannot be replaced. While overcharging a lead-acid batteries, causes the electrolyte water to break into oxygen and hydrogen gas, which depletes electrolyte levels in the batteries.

Q: Can a dead gel battery be recharged?

A: Gel batteries are disposable - there is no way to recondition them. With careful recharging you can sometimes get a little life out of them but it is usually a disappointing business, and they fail when the weather is cold and demand on them is high. Better to swap them for a new one.

Q: Is a gel battery worth the extra money?

A: Even though gel batteries are pricey, it's worth investing in one because: They are leak-proof because there are no liquid electrolytes in them and all acids are suspended in a solid matrix. Gel batteries contain acid within the housing, making it safe to handle the batteries without gloves.

Q: Can you jump start a gel battery?

A: What types of batteries can Boost jump? All Boost models (except the GB500 Boost Max) can jump start 12V lead acid batteries only. This includes wet, gel, maintenance free, enhanced flooded battery, and absorbent glass mat batteries. The GB500 Boost Max is capable of jump starting 12V and 24V acid batteries.

Q: How do I know if my gel battery is bad?

A: Cells that are not taking a full charge or cells with any signs of bubbling on top would require replacing the gel battery as well. -If there's no corrosion and all cells are holding their proper voltage, you may have an alternator problem rather than a bad gel cell battery!

Q: How do you maintain a gel battery?

A: There will be no need to do routine maintenance. There will be no spills, providing no considerable and hazardous risk because you will not come into contact with the acid. Because of the low amount of corrosion, gel batteries can be used with sensitive electronic equipment.
