Tips on How to Buy Rechargeable Batteries

Many people purchase rechargeable batteries without even thinking about the differences among each kinds 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 are some tips on how to buy rechargeable batteries so that you can get the most out of your money.

The initial thing that you have to consider in how to buy rechargeable batteries is the different types of rechargeable batteries. There are three major types of off-the-shelf rechargeable batteries, nickel metal hydrides, nickel cadmiums, and rechargeable alkaline manganese batteries. A nickel metal hydride battery is the most expensive of the three but it also has the most energy capacity.

The nickel cadmium battery is the middle ground between nickel metal hydride and rechargeable alkaline manganese. It has a sufficient energy capacity but it is not as high as those of nickel metal hydrides and it can be unpredictable 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 understand on how to buy rechargeable batteries is type of device that where you are going to attach the batteries. Fast-draining gadgets especially those that have LCD screens like digital cameras and mp3 players can take advantage of nickel metal hydride’s high energy capacity. Meanwhile those devices that still need a fair amount of power like wireless mouse, battery-operated toys, and portable radios can utilize the less pricey nickel cadmiums. Devices that do not use too much energy or those that are not often used such as flashlights and remote controls can manage on rechargeable alkaline batteries.

The last thing that you have to consider in how to buy rechargeable batteries is the expected frequency of usage of the device that where you are going to put the batteries. The reason is that various types of batteries have different self-discharge rates. Nickel metal hydride batteries self-discharge at the fastest rate at 30% per month even when not contained within a device. Following that is the nickel cadmium batteries at 10% per month. Rechargeable alkaline manganese batteries meanwhile can store their charge for years.
