It’s good to know that you can’t recharge your car battery by letting it run if it is below 12 volts. I would like to get my car battery tested this month to see how it is performing. It’s an old battery, so I want to make sure that it’s still up to par. https://southsideservicecenter.com/
Using a battery pack above the operating temperature that it's rated for will damage the battery over time. This will result in the battery aging much faster than it otherwise would have.

Measure the voltage of a repaired pack and check it again after 24 hours and a few days. If a cell drops lower than another in the pack, then there is fear of elevated self-discharge(See BU-802b: Elevated Self-discharge) Simple Guidelines when Repairing Battery Packs Only connect cells that are matched. Do not mix cells of different chemistry, age or capacity.Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit.Include a temperature sensor that disrupts the current should the pack get hot.Apply a slow charge to a repaired pack to bring all cells to parity.Pay attention when using an unknown cell brand. Elevated temperature hints to an anomaly.Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time.Check a repaired pack for self-discharge. Intrinsic defects often reveal themselves in an elevated self-discharge. Previous Article Next Article
The power meter reported a range in power between 2 and 18.3 watts during the charging period, consuming 0.046 kWh in total. From my utility company, that represents around $0.005 worth of electricity.
