This by-reaction makes water loss gradually and pure water need to be added regularly
to keep the battery operate normally.
Eos battery adopts a design of barren-liquor and utilizes AGM (micro porous glass
fiber) separator. Thus there is a path existing between the positive and the negative.
Also special alloy grid is chosen to increase vent hydrogen over-potential gassing on
the negative plate, which prevents generation of hydrogen. Otherwise, the oxygen
generated from positive diffuses through separator to the negative and the oxygen gas
reacts quickly and is recombined into water. The reactions are as follows:

2Pb +O
