MAINTENANCE CHECKLIST

As per the epidemic of COVID-19, many places are locked down or carrying out quarantine policy, which would cause the consumption ability going down and the longer the storage time of the cargoes/goods. Considering the charateristics of lead acid batteries,here is the lead acid battery maintenance checklist.

Recharge:

recharge voltage 14.4V-14.8V, recharge currency 0.1C, constant voltage charging time: 10-15 hours.

If not recharged, the batteries may not be working due to high internal resistance.

Recharge 30 mins of the dry charged batteries if it is stocked in warehouse more than one year; or the battery internal plates are oxidated in winter season with low temperature environment (recharge voltage 14.4V-14.8V, recharge currency 0.1C).

Do not turn the battery upside downin case acid leakage from the safety valve.

If leakage happening, please take the leaking batteries from the others and clean it; in case the acid causes batteries short circuit. After cleaning the leaking batteries, please recharge the batteries as above steps.

Songli Battery is a global lead-acid battery technology expert. In addition, we have become one of the world's most successful independent battery manufacturers.We sincererly thank you for your always trust on our battery products and service, and we are also improving ourselves and products to provide you more excellent products and service.

Recomended temperature for  lead acid battery maintenance:

10~25℃(High temperature would speed up the battery self-discharge). Kepp the warehouse clean, ventilated and dry, and avoid direct sunlight or excessive humidity.

Warehouse management principle: First in First Out.

VRlA battery

Those batteries which are stocked in warehouse with longer time sold in priority,in case the battery voltage under low. It is better to divide different storage areas in the warehouse according to the arrival date as shown on the cargoes package.

Testing and inspecting of the sealed MF batteries’voltage every 3 months in case the batteries’ voltage under low or cannot start up.

Take the 12V series battery for instance, pleasure recharge the batteries if the voltage is under 12.6V; or the battery may not start up.

Lead acid batteries stocked in the warehouse more than 6 months, please do the voltage inpection and recharge the batteries before selling to essure the batteries in normal status.

Steps of battery recharge and discharge:

 

①Battery Charge: charge voltage 14.4V-14.8V, charging currency:0.1C,constant voltage charging time:4 hours.

②Battery Discharge:discharge currency:0.1C, End of discharge voltage 10.5V of each battery.

③Battery Recharge:recharge voltage 14.4V-14.8V, recharge currency: 0.1C,constant voltage charging time: 10-15 hours.

As bellowing picture shown, please coordinate with our sales team if there is any questions about the usage of the device and then we could provide you the operation video.
