12V 200Ah GEL Battery

Overview

The Huayu 12V 200Ah GEL Battery is a GEL chemistry based solution used for energy storage, backup power, and other similar systems with daily cycling. The battery is featured with leak-proof, maintenance-free design, no toxic gas generation, vibration resistant, and provides outstanding performance at -20°C~60°C temperature and longer storage time used in virtually any position like marine, RV, van, home backup power, etc.

Product Highlights

Longer Storage Time

• Monthly self-discharge rate below 3% at 25℃, 5 times lower than counterparts.

• No need to recharge the dormant battery frequently.

Extended Service Lifetime

• Corrosion-resistant grids enable 12-year design life;

• Over 1000 charge/discharge cycles at 50% DOD.

Maintenance Free & No Acid Leakage

• Comprised of gel instead of liquid, no maintenance required to keep the battery working properly.

• Manufactured with an advanced valve regulated technology, avoid acid leaks and frequent maintenance.

Excellent Deep Discharge Recovery

• Proprietary plate composition and patented gel electrolyte ensures excellent recovery capability after excessive deep discharge. It means this GEL batteries can discharge more and still be recharged like new.

Free and Easy Installation

• Maintenance free, no leakage, no toxic gas generation, vibration resistant, and stable performance at 60°C and -20°C temperature make this GEL batteries used in virtually any position like marine, RV, van, home backup power, etc.

In Series and In Parallel to Expand Power Capacity

• This battery can be connected 4 batteries in parallel to expand the power capacity. And no limitations in series connection.

Q: If this GEL battery can be used in a living/working area?
A: This GEL battery is suitable for on-grid and off-grid applications and does not generate any toxic hydrogen gas during working, so it's a safe and clean battery. You can use it in your living/working area for on-grid and off-grid applications like marine, RV/Van, home backup power supplies, emergency power systems, medical devices, etc.

Q: What is the maximum charge current? Optimal charge current?
A: The max charge current for this GEL battery is 40A. The optimal charge current should be based on whatever the charge controller will give it as the optimal charges based on the current level of the battery.

Q: Can I connect the GEL batteries in series and in parallel?
A: Yes, you can. The maximum number that can be connected in parallel is 4. As for in series, there is no limitations. We recommend connecting the batteries with the same voltage and capacity from the same brand. And we also recommend using a battery balancer to extend the battery service life when multiple batteries are connected in series and/or in parallel.

Q: How to maintain the battery?
A: The battery should be stored in clean, ventilated, dry and cool ( -20℃~60℃ ) place when not using, keep it after full charge, recharge it every 3 months or 6 months.

Q: How can you tell if a battery is good or bad?
A: You should first check the battery for defects such as a broken circuit, a short, or a broken container. If an outward problem is not apparent, then you will have to check the battery's capacity using known measuring techniques to ascertain the problem.

Q: How can I fix this GEL battery if I over discharged it?
A: It can be restored to normal voltage and continues to operate normally through low-current charging. Please note that frequent over-discharge may cause irreversible damage to the battery's life. To avoid cycle-life shortening, we recommend not discharging the battery below 50%.
