All About How To Buy Rechargeable Batteries

Numerous people buy rechargeable batteries without even taking into consideration the differences between each type of batteries. However, every type of batteries has its own merits and limitations thus a certain type may be more practice in some situations than others. Here is a guide on how to buy rechargeable batteries so you get the most value out of your money.

The first thing that you need to know in how to buy rechargeable batteries is the different kinds of rechargeable batteries. There are three common types of off-the-shelf rechargeable batteries and they are nickel metal hydride batteries, nickel cadmium batteries, and rechargeable alkaline manganese batteries. A nickel metal hydride battery is the most costly of the three but it also has the largest energy capacity.

The nickel cadmium’s energy capacity lies between the nickel metal hydride and the rechargeable alkaline manganese. It has an adequate energy capacity but it is not as high as those of nickel metal hydrides and it can be unstable depending on the temperature. The rechargeable alkaline manganese battery is the least expensive of the three but it also has the lowest energy capacity and it can only endure several charge/discharge cycles.

The next thing that you have to learn about how to buy rechargeable batteries is the kind of device that where you will put your battery to use. Devices that uses a lot of energy especially those that have LCD screens such as digital cameras and mp3 players can benefit from the nickel metal hydride’s high energy capacity. Meanwhile those gadgets that still need an average power such as portable radios, wireless mouse, or battery-powered toys can use the less expensive nickel cadmium rechargeable batteries. Devices that have minimal power requirements or those that are seldom used like remote controls and flashlights can operate on rechargeable alkaline manganese batteries.

The last thing that you have to take into account in how to buy rechargeable batteries is the estimated frequency of usage of the device where you intend to use the batteries. This is due to the fact that different kinds of batteries have various self-discharge rates. Nickel metal hydride batteries self-discharge at the fastest rate at 30% per month even when not contained within a device. Next is the nickel cadmiums at 10% per month. Rechargeable alkaline manganese batteries meanwhile can store their charge for years.
