Why are rechargeable batteries not recommended?
Rechargeable batteries are great for certain applications and when used correctly can be an excellent option. Rechargeable batteries are usually more expensive than single use batteries.
Is Energizer better than Duracell?
When it comes down to the choice between Duracell and Energizer, there's no outright winner. Both brands use the best technologies and aren't significantly different in any other features. Whether you want to go with Duracell or Energizer is a matter of preference but they're both legitimate options. One thing to keep in mind is that Energizer uses an internal power supply, so if you have any issues with batteries in your device, you might be better off with Duracell
Does a higher mAh battery last longer?
The mAh rating is a standardized measurement of the average capacity of a battery in milliamperes hours (mAh). The higher the rating, the more capacity the battery has to offer. The mAh rating is generally a measure of the battery's capacity for a specific use or set of uses. In general, it's best to choose a battery with a higher mAh rating to provide more overall capacity, even if the battery will be used for a shorter period of time.
How do I choose a rechargeable battery?
For most cell phones, a lithium battery is best. Lithium batteries have the highest energy density of all rechargeable batteries. A cell phone with a lithium battery can last longer between charges. If you are using a rechargeable battery for something that will need to be recharged multiple times, such as a computer, a rechargeable battery with a lower energy density such as a nickel-cadmium battery is recommended.
