What is the difference between NIMH & Li ion batteries?

In general, NiMH batteries start out at 1.5 V but quickly drop down to 1.2 V while in use; this can cause problems in some devices (like a digital camera that can’t hold a charge or an analog clock that can’t keep time), whereas Li-ion batteries maintain a high voltage until right before they die.

Are rechargeable batteries better than disposable batteries?

Regardless of whether you pop them into a wireless mouse, a toy, or a flashlight, rechargeable AA and AAA batteries almost always last longer, cost less, and result in less waste than their disposable counterparts. After spending thousands of hours researching and testing rechargeable batteries, we found that many perform about the same.

Are NiMH rechargeable batteries better than NiCd batteries?

NiMH rechargeable batteries hold a charge longer, can be recharged more times over their life spans, and have higher capacities than those made with NiCd. Even with the added cost of a charger, rechargeables will pay for themselves in five to six recharges, compared with the cost of most brand-name disposables.

Can you use a rechargeable battery instead of a lithium ion battery?

If you own such a device (and if you’re unsure, it’s most likely listed on the bottom of the device or in the manual), you can use a rechargeable Li-ion battery instead of a disposable lithium or alkaline, since all three operate at a constant 1.5 volts.
