Pls note the charger is not What to Do When You Receive a New Battery?
A:When you receive your new battery, it might arrive with a low state of charge (SOC) due to transport and storage. To ensure optimal performance, it\'s important to charge the battery right away to prevent over-discharge.
If your battery features Bluetooth functionality, such as the 12V 165Ah lithium battery, it may come powered off, displaying a terminal voltage between 3V and 5V, which means you won\'t be able to connect it to your phone. This shipping method helps minimize self-discharge and prolongs the battery\'s lifespan, similar to how mobile phones are shipped.
To resolve this issue, you can use one of two methods: either an AC-DC lithium battery charger or an MPPT solar charge controller. Simply charge the battery for 3 to 10 seconds to enable normal usage.
If you plan to store the battery for an extended period, charge it to a SOC of 50% and perform maintenance checks every three months. This practice will help maintain its functionality and performance.
Q: Do You Have a Battery Box for Group 31?
A:Yes, LiTime has a portable battery box for group 31. Built-in voltmeter allows it to be used for marine and RV applications, fitting group size 24, group size 27, and group size 31 batteries.
