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 voltage 14.4V-14.8V, recharge currency 0.1C, constant voltage charging time: 10-15 hours.
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).
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.
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.
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.
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.
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.
3.2.1.Charge: charge voltage 14.4V-14.8V, charge currency：0.1C，constant voltage charging time：4 hours.
If operation video needed, please inquiry with our sales team. Thanks.
Quick discharge the batteries at 1C discharge rate until the battery voltage down to 10.5V. If operation video needed, please inquiry with our sales team. Thanks.
