Datasheet of Free Maintenance Tubular GEL Battery



Specification & Feature of Free Maintenance Tubular GEL Battery



Nominal Voltage(V)





Cells Per Unit








 Approx. 56.0Kg

Container Material


Storage life

After fully charged, it can be storaged about 2 years at 20℃

Flooded electrolyte


Contain more electrolyte like a flooded battery, pace between plates,

separators is full of electrolyte thus means good heating capacity.



Approx. 0.55 mΩ

Max. Discharge Current

3000A (5 sec)

Positive plate

Tubular type, with die-casting thick Pb-Ca grid; it has very good

corrosion resistance and a very long service life

Normal Operating Temperature






Negative plate

Pasted flat type, radial grid design, good high rate discharge performance

Float charging


2.25 to 2.3 VDC/unit Average at 25℃


Gel electrolyte uses imported silica, special tenichnics make it in a gel

immobilized state, special additives make it very stable, lower internal

resistance and no stratifiction;


PVC-SiO2 separator, low internal resistance, high pore rate and long life

Safety valves

Good sensitivity, safe, reliable, equipped with double flame arrester

Equalization and Cycle Service

2.37 to 2.40 VDC/unit Average at 25℃

Compliant Standards
1. IEC 60896-21/22-2004/ DIN43539-T5
2. IEC61427-2005/ YD/T1360-2005/ GB/T 22473-2008
