If you don’t utilize the batteries for some weeks or more than that, put them on a trickle charger in order to preserve performance. The stored battery slowly loses its charge which leads to the buildup of sulfur on the lead plates.
If a battery is acting strangely then you should not use it. An undiagnosed bad battery could have one or more things wrong with it. Some types of battery damage pose no safety risk by using the battery and other problems do. The fact of the matter is until you learn how to identify and fix a broken battery, you can only guess.

Well, I will still ask, Maybe someone out there can help. Have a HP DV7 Notebook with a 9C battery. 3 cells died over night. from running normily to zero. Disassembled battery to find 3 cells died. zero Volts. Replace the 3. Now have ~12.6V. Will not charge in windows, Shows 80%. ran Bios battery test. Battery status : Replace (42). was wondering if anyone out there has a way to reload the firmware in the battery charging pcb or edit that data? Many thanks David A.
Note: If you aren't used to doing this sort of thing, or using things like a "multimeter" this is going to seem crazy and hard and way out of your DIY league. It isn't.
Touching the red probe to the positive (red) terminal and the black probe to the negative (black) terminal, read the voltage shown on the multimeter. In my case the battery was carrying a charge of 0.06 volts. Which is *almost* nothing, but not completely nothing.
If you have a vehicle equipped with an internal combustion engine, you probably have a flooded lead-acid battery beneath the hood. In comparison, hybrids generally contain a nickel-metal hydride (NiMH) or a lithium-ion battery, while an electric vehicle is going to include a large Li-ion battery pack for a longer driving range.
The Li-ion battery i have is sealed, no screws at all, can i still pulse charge this battery using the +- terminals that are visible on the outside of the battery? (its a godox VB18 camera flash battery DC 11.1V 2000mAh)
From the easiest-to-fix to the most complicated, here are the most common reasons your vehicle’s battery can’t hold a charge:

If a relatively new pack has only one defective cell and a replacement is located, exchanging the affected cell makes sense. With an aged battery, however, it’s best to replace all cells. Mixing new with old causes a cell mismatch that has a short life. In a well-matched battery pack all cells have similar capacities. An anomaly is a chain in which the weakest link determines the performance of the battery(See BU-302: Serial and Parallel Battery Configurations)
Is that battery really dead? You can tell if a battery needs replacing. This Fix-It Guide on battery testing tells how a household battery works, what often goes wrong, how to identify a battery problem, and what parts and tools you will need to fix it. It then gives simple step-by-step instructions for how to test a household battery. See button battery repair for small specialty batteries.
This doesn’t mean EV batteries are indestructible, however. Certain conditions, like extreme heat, can take a toll on them, just as they take a toll on the batteries in gas-powered cars. If you’re worried about the condition of your EV’s battery, have it assessed by an experienced professional.
The place of your restored battery pack is usually a SR-50(A), SR-51(A), SR-52, SR-56, TI-58(C) or a TI-59.
