Batteries in stock:

A wet-charged battery will be discharged by itself even under not-in-use condition.The battery should be charged if it is stored for more than three months.

Keep the battery in a dark, cool place and measure the open circuit voltage once a month.

if the battery has been left for a long period at a low open circuit voltage, battery will be sulfated and the battery cannot be fully recharged,or at the worst, cannot be recharged at all.

Charging Batteries:

 It is recommended to use constant current and constant voltage charging.

Typically 120 to 130% volume of discharged ampere-hour will be charged.

Do not forget to disconnect the charging power source when the battery is completely charged.

If not it will continue feeding the same amount of current to the battery resulting in the overcharge of the battery.


 Daily Battery use instructions : 

 Perform charging at a place which is free from direct sunshine, rain, dew, moisture, but well ventilated, acid proof, washable and well drained.

Connect the charger terminals to the battery terminals tightly and correctly. Incorrect connection will deteriorate the functions, and may cause damage to not only the battery but also the charger.

Do not overcharge. Excessive charge may cause overcharging, resulting in damaged plates and separators and distortion of softening container due to high temperature.

Never bring the battery close to fire: Explosive hydrogen and oxygen gas from the battery will catch fire.

Keep battery temperature below 45°C. When it reaches near such temperature, decrease the charging current by half or stop charging until the fluid goes down to 35°℃.

For batteries with indicator, if the indicator turns white during use, it may caused by the bubbles around the indicator ball. Shake the battery carefully, if the indicator turns green, it means the battery can still be used. If the indicator keeps white, the battery is in lack of electrolyte. Then the battery should be replaced.
