Technical Features
Technical Parameters
Special carbon additives are adopted in the negative plate, so the plate sulfation is restrained
and can achieve more than 3800 cycles at 60% DOD
The unique recipe and process boost the low temperature performance by 20%
Superb security and reliability, the unique sealing technology can avoid leakage effectively
The particular structure design with low resistance improves the corrosion-proof performance
and charge acceptance capability effectively
Excellent over discharge recovery capability, the 100% capacity can be recovered after short
circuit 10 times
