The CHIWAY sealed lead-acid rechargeable battery (VRLA battery) is leak-proof and maintenance free. The
Superiority of VRLA battery is derived from its uniquely efficient oxygen recombination technology. The oxygen
evolved from the positive plates diffuses through the micro porous glass fiber mat to the negative plates where it
is changed back to water by recombination reaction, eliminating the need for water addition .The result is a
maintenance free battery.
