FAQ

1. Why the electrolyte temperature is too high? How to deal with it?

A: The high temperature of electrolyte after acid filling of new batteries is due to the neutralization reaction between the acid and the oxidized negative plates, which will generate lots of heat. During this period, charging should start when the electrolyte temperature drops to about 40 ℃, or charge the battery with low current.

During normal charging process, if electrolyte temperature is high or even exceeds 45℃, cooling measures should be taken, or adjust the charging current to a low value. If temperature shows no decrease, possibility of battery internal short circuit or plate’s sulfation should be considered.

During normal usage of battery, if the temperature is too high. There are two possibilities to this: one is because the surrounding ambient temperature is too high, and the heat generated by battery is not easy to dissipate. The other is that the charging voltage or current is too high.

2. How to deal with abnormal charging?

A: When recharge a normal battery, no massive bubbles(gas) would be generated at the primary charging period, since the current charged only serves for the electrochemical reaction of active mass. While at the end of charging period, along with the completion of electrochemical reaction, current charged begins to electrolyze water, and degases hydrogen and oxygen.

When recharge the battery after usage, if only little gas is generated at the end charging period, it may be because the charging current is too low or battery is still not fully charged. If one single cell shows no gas generation during battery charging, this may indicate internal short circuit. If the whole battery produces too much gas and too early, this indicates the possibility of plates sulfation, which should be treated with repeated discharge and charge processes. If the battery produces gas in resting period or discharge process, it may be caused by much impurities in electrolyte.
