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
