As a big battery manufacturers in China, we supply many different kinds of batteries , such as the lead acid AGM battery, Gel battery, Deep cycle battery, OPzV Tubular battery, OPzS Tubular battery ..etc .
The following is our 12v120ah OPzV Battery features :
1. Service life up to 18-20 years in continuous float operation down to approx 80% capacity.
2. Completely sealing throughout the batteries life.
3. Gel electrolyte.
4. Easy to move and handle.
5. Minimum space required and room requirements are minimal e.g. no washing facilities needed, ventilation requirements are minimal.
6. Low gassing thanks to antimony-free alloy and internal oxygen recombination.
7. Easy install using cable connectors with insulated terminal covers.
8. High cyclic ability over 600 cycles when discharged at 10 hour rate to an end voltage of 1.8Volt/cell at 20℃ .
9. Can be supplied as a standard vertical installation or by special request, for a horizontal installation.
10. Very low self-discharge <50% of rated capacity in 2 years at 20 ℃ ambient temperature.
11. Ready for immediate use without further commissioning work.
12. Deep discharge protected, a load can be connected to the battery for up to 4 weeks.
13. No internal short circuits possible due to the gel structure.
14. No acid stratification, so noequalizing charge necessary.
