3) The batteries don't like to sit at 100%. Once it's charged, take it off the charger. Bonus points if you put it right into a tool and turn it on for like 5 seconds. Now it's at like 95% charge, it's much happier, battery is now ready for storage and doesn't need to be touched for a year.
Then why have SO many people thanked me for this post Peter? Which by the way isn't a post on pulse charging lithium ion batteries, it's a post on how to trick your charger into charging your batteries again. ~ karen!
1. Re-matching: After the whole group of lithium battery packs are damaged, we often charge and discharge the electric vehicle lithium battery. In the inspection, it is often found that 50% of the batteries in a group of batteries are not damaged. The reason is that in the series-connected lithium battery pack, the function of the individual batteries behind the formation of the entire battery is degraded, so that the function of the entire battery is degraded.
How to choose properly: check for its accuracy before purchase. A good multimeter has error bar of 0.025-3%.

Some batteries are equipped with a solid-state switch that is normally in the “off” position and no voltage is present at the battery terminals. Connecting the switch terminal to ground or pulling it up often turns the battery on. If this does not work, the pack may need a code for activation. Battery manufacturers keep these proprietary codes a well-guarded secret to which even service personnel have no access.
1. Use a clean eraser or other cleaning tool to gently wipe the metal contacts on the lithium battery and the metal contacts on the phone to help with the charging status and power lasting.

Fixing an ebike battery is similar to fixing a drill battery. The main difference is that an eBike battery will have many more cells and will have a higher running voltage than most drills batteries.
If you have an electric vehicle (EV), you won’t need to worry about battery maintenance—aside from charging, of course. EV batteries typically last 10 to 20 years, so unless you keep the same EV for several decades, you likely won’t need to replace your vehicle’s battery.

When repairing a Li-ion pack, make certain that each cell is properly reconnected to a protection circuit(See BU-304: Why are Protection Circuits Needed? and BU-304a: Safety Concerns with Li-ion) With the exception of some single-cell and power-tool packs, all Li-ion batteries must have a protection circuit; lead and nickel-based batteries are exempt.
