Maintenance free, no need to add water or other maintenance during use.

Heavy Duty Grids

High reliability, safe without leakage.

Low self-discharge rate, with an average monthly self-discharge rate below 2.5%.

High energy density which can output more energy.

Higher energy density. 20% higher than that of the same volume product under high discharge rate. 

It can be charged continuously for 48 hours without leakage, and caan be used in any direction such as side,horizontal,and upside down.
Adopt optimization design under deep discharge, and the residualcapacity shall not be less than 50% of rated capacity after 96 times of 100hr full capacity cycle life.
It still can be used normally after fully battery storage 2 years, and witaffecting its service life.
it still can be used normally after continuous storage for 120 days at 50%SOC.and without affecting its service life.
Unique lead paste formula and plate ratio design. After the batteryis discharged to 0V, the wires are directly short circuited for 3 days. After recharging, the cycle tesst is conducted 3 times,and the discharge capacity recovers to over 95% aftei 100 hours.
Meet the RoHS and REACH standards of the EU Battery Directive.

FAQ

Q: What is a Valve-Regulated Sealed Lead-Acid Battery (VRLA)?
A: A VRLA battery is a sealed lead-acid battery that utilizes internal oxygen recombination technology (oxygen recombines at the negative plate to form water) for maintenance-free operation. It is equipped with a safety valve to prevent excessive pressure buildup. There are two types: AGM (Absorbent Glass Mat) and Gel.
Q: How is a VRLA battery different from a conventional flooded lead-acid battery?
A: Sealed & Maintenance-Free: No water refilling is needed; the electrolyte is absorbed (AGM) or gelled (Gel).Oxygen Recombination: Minimizes gas emissions and allows horizontal installation (though upright is recommended).Safety Valve: Releases excess pressure to prevent swelling.
Q: Does a VRLA battery require an initial charge?
A: It comes pre-charged, but if stored for over 6 months, a supplementary charge is recommended before use (use constant voltage charging as per the manual).
Q: What is the correct charging voltage?
A:For 12V Batteries:Cycle Use: 14.4-14.8V (lower for Gel batteries).Float Charge: 13.6-13.8V (to maintain charge without overcharging).Always follow the manufacturer's specifications-excessive voltage can cause water loss or thermal runaway.
Q: How to determine if a battery is end-of-life?
A: Replace if:Capacity drops below 60% of the rated value.Voltage drops rapidly after a full charge (e.g., s12.0V for a 12V battery at rest).Internal resistance increases significantly (requires specialized equipment).
Q: How to store an unused VRLA battery?
A:Fully charge before storage.
