Which is better alkaline or NiMH batteries?

They provide higher performance than a standard alkaline battery and can be up to 1/3 lighter for when weight is an issue, not only this but they can have up to 10-year storage life. Nickel Metal Hydride (NiMH) – NiMH batteries can sometimes provide double to three times the capacity of a similarly sized NiCD battery.

What are NiMH batteries good for?

NiMH batteries are ideally compatible with most consumer devices such as digital cameras, game boys, CD players, RC vehicles, PDA’s, portable two-way radios, flash units and many more high drain devices.

What is the lifespan of a NiMH battery?

Typically NiMH batteries can be recharged hundreds of times, potentially allowing them to be equivalent to hundreds of alkaline batteries in total service over their lifetime. However, battery life is limited to 5 years or less.

Why should you not use rechargeable batteries?

Rechargeables are not only more money than single use batteries, but the price of a quality charger may negate their value altogether depending on use. Another potential problem with rechargeable batteries is that they can often become weak and unpredictable with age.

Can you replace NiMh batteries with lithium?

Unfortunately the answer is a solid NO. Reasons why: The NiMh cells are very likely high current cells, meaning they are designed to be able to deliver the high current that a vacuum cleaner motor needs.

Can old NiMH batteries be revived?

Old NiMh cells internally have crystalization that forms between the positive and negative plates. In order to revive the cell you have to shock the battery and break the short that the crystalization creates.

Can you fix a NiMH battery?

Well, like most other rechargeable batteries, you don’t need to take apart a NiMH battery to recondition it. All you need to do is run a few deep charge cycles to improve the battery’s performance and bring it back to speed.
