Remote controls can use either standard AA and AAA batteries or include a custom rechargeable pack. Battery life is determined by many factors, including backlighting, LCD screen, the amount of use and signal strength. The average battery life for an all-hard button remote control is greater than one year, while backlit LCD models may go anywhere from several weeks to several months.

Digital camera batteries include: Nickle cadmium (NiCad) rechargeable batteries. They use an alkaline electrolyte, have a longer life than non-rechargeable and have memory. A nickel metal hydride (NiMH) rechargeable battery lasts longer than a NiCad and has no memory. Lithium ion batteries are more costly than the NiCad or NiMH, but hold a charge much longer.
Types of batteries for wireless or cellular phones listed below illustrate some of their advantages and disadvantages. Most cellphone handset units will accept a "standard" or "extended" battery, with additional output of the extended adding to the length of time the battery will power the handset. Battery types NiCad or NiCd means Nickel Cadmium. Nimh refers to Nickel Metal Hydride. Li is for Lithium. Most cell phones manufactured today are equipped with lithium batteries. Thers are far superior to the older and less expensive ni cad batteries. Here are their distinguishing characteristics
a hassle when compared to using a custom rechargeable battery, but remember that AAs can be replaced on the road when there's no charger around
a silicon chip with sales in core consumers, buy solely based alkaline
Two or more cells in series. Primary batteries are those which can only used once, where as secondary cells are those which can be used again by recharging the battery.
The TEMPO+ is unique in that it has very long battery life. Three of the four battery packs available with the TEMPO+ run on size 675 batteries (for an average battery life of 3-5 days). These batteries can be purchased at many drugstores as well as hearing aid dealers. It is critical that they are labeled as "high power" batteries. Size 675 batteries that are not labeled "high power" will result in very short battery life because their power levels fluctuate enough to signal a dead battery to the processor, even though the batteries may be fully charged. The remote battery pack uses one size AA battery (either rechargeable or alkaline).
The most common types of batteries for wireless phones are listed below, with their various advantages and disadvantages. Regardless of the technology, most handheld and portable units will accept a "standard" or "extended" battery, with the additional output of the latter adding to the length of time the battery will power the unit.
Batteries for digital cameras can range from AA size to NiCad (nickel-cadmium), to NiMH (nickel-metal hydride) to lithium ion. nickel cadmium (NiCad): Rechargeable batteries that use an alkaline electrolyte. They have a longer life than non-rechargeable batteries. NiCad batteries have a memory, so they need to be run all the way down before recharging. Otherwise, they will begin to run out of power sooner. nickel metal hydride (NiMH): A rechargeable battery that lasts longer than a NiCad and has no memory, so it is easier to manage. lithium ion: More expensive than either the NiCad or NiMH, but holds a charge much longer.
