FAQ

1. Why is the battery voltage abnormal?

A: After charging, the voltage of each single cell should be around 2.1 V (may be affected by electrolyte density). If the voltage is low during primary usage, check if battery is fully charged or if electrolyte density is too high or too low.

If battery shows comparatively higher voltage during charging, along with numerous bubbles and voltage drops fast during discharge, this may indicate plates sulfation. Fully discharge the battery with low current and then charge the battery with low current (0.1C20), repeat the discharge and charge steps several times. The effect of this method may be affected by the sulfation degree.

2. What is the effect of abnormal electrolyte density and indicator color?

A: During battery charging and discharging processes, electrolyte density should vary from 1.070 to 1.290g/cm3. Density increases during charging and decreases when discharging.

a. If density is too high, it will cause plate sulfation and accelerate grid corrosion; while if density is too low, it will affect discharge capacity.

b. Under normal charging conditions, if the density does not increase significantly or even remain unchanged, there is a possibility of plate’s sulfation, which may need countermeasures to eliminate sulfation.

c. After the battery is charged, if the density decreases significantly during the resting period, it indicates the sever battery self-discharge, which may be caused by too much impurities in electrolyte. If electrolyte shows abnormal color or smell, or even shows turbidity, it indicates that the electrolyte is impure and impurities has got into the battery.

d. If electrolyte shows the color of metal ions, there is a possibility of contamination.
