What about nickel metal hydride li ion 18650 battery pack
How to repair nickel-metal hydride batteries. In theory, nickel-metal hydride batteries have no memory function. Batteries with reduced capacity due to memory effects can be discharged multiple times, and most batteries can be repaired. The main characteristics of NiMH batteries are low internal resistance and large discharge current, so many digital cameras use 1.2VNiMH batteries.
NiMH batteries are currently used in other products and require specific understanding of their use and maintenance. Many NiMH rechargeable batteries are complete and most have already been released. Because the nickel-metal hydride battery has a self-discharge reaction, the nickel-metal hydride battery will not be overcharged for a long time. The internal resistance is too large, the battery cannot be charged, and the battery will be wasted. The following energy storage electronics editor will introduce how to repair nickel metal hydride batteries.
1. Completely discharge the nickel-metal hydride battery. Depending on the current condition of the battery, when the discharge voltage of the load is close to 0 volts, it will take about 5 to 10 hours to short-circuit the battery directly or use a 1 ohm resistor. This prevents the battery from burning due to an accidental short circuit after adding water and reduces the possibility of overflow.
2. Boil the battery with boiling water until the foam stops foaming. But do not cook the battery, boil water and burn it. Immediately place in a bottle of cold (room temperature) purified water and wait about 1 minute. If a small amount of water is inhaled, please tighten the bottle cap immediately and add water for about 10 seconds.
3. After 5 hours of storage, charge should be repeated 3-5 times. Fast charge for about 30 minutes, then charge slowly until the terminal voltage exceeds 1.45V (which takes a long time), then use a medium or slow charger.
