Every mobile electronic device we own runs on battery power, yet we take batteries for granted - at least until they run out of juice. No matter what kind of device battery - laptop battery, cell phone battery, camcorder battery, remote control battery - you need, it's helpful to know the various kinds of battery types and their uses.
Gel Battery - A gel battery is also known as a sealed lead acid (SLA) battery, and its distinguishing feature is that it doesn't have to be kept upright in order to work. An SLA battery continues to perform in extreme conditions, such as hot temperatures, or under vibration. SLA batteries are often used in wheelchairs, scooters, and uninterruptible power sources. It's best to keep an SLA battery charged, or to charge it more often than you would other types of batteries.
Battery Tool
NiMH - NiMH stands for Nickel Metal Hydride and is the battery of choice for many cell phones, camcorders, digital cameras, GPS systems, PDAs, and other personal electronics. NiMH batteries are also used in hybrid cars. An NiMH is a rechargeable battery that is similar to a nickel cadmium (NiCd) battery, but that has double or triple the capacity of a NiCd battery. It's best not to overcharge NiMH batteries.
NiCd - NiCd stands for Nickel Cadmium, and is a type of rechargeable battery commonly used in toys, electronic devices, and power tools. Although some people prefer NiMH batteries to NiCd batteries, a NiCd battery provides virtually the same level of voltage throughout its lifetime, and costs less than an NiMH battery.
LiION - LiION stands for Lithium Ion, and is one of the newest rechargeable batteries. Although they are more expensive than other types of rechargeable batteries, LiION batteries have more capacity and are often used in wireless phones, camcorders, and notebook computers. The downside of LiION batteries is that the length of their life commences from the date of manufacture, rather than from the number of times the battery is charged and discharged. It's best to regularly charge LiION batteries and store used batteries in the refrigerator. (Allow them to warm to room temperature before using them, though.)
Alkaline - Alkaline batteries are not rechargeable with a battery charger, but offer a large current over a long period of time. These batteries are often used in CD players and portable radios.
Carbon Zinc - Carbon Zinc batteries are known for their reliability over long periods of time in low-drain situations, such as for garage door openers or clocks. A Carbon Zinc battery is not rechargeable.
