1. Lead and autunite alloy grid, ointment formed pole board, large content, long service life.
2. Lead-tin multi-alloy collector, small internal resistance, antirust that can float recharging for long period.
3. Advance AGM clapboard, that can absorb all the electrolyte without leaving dissociate liquor, can fulfill gas ka absorption, it also can be used in random place.
4. ABS plastic shell is fastness and anti-aging.
5. Silicon-fluoric rubber sealing safety helmet is safe and explosion-proof without leakage of erode gas.
6. Silver-plating copper terminal with small resistance and antirust.
7. Analyze pure electrolyte with little local action.
