Frequently Asked Questions

What is the difference between wireless phone batteries?

Nickel Cadmium (NiCad) batteries offer strong dependable performance, hold their charge for weeks and work very well in extreme heat or cold. They can take more charges than any other type of battery. They are also the less expensive alternative. As the "old reliable" of the portable cellular market, NiCad batteries are always available for every phone. These are generally best for the infrequent user.

Nickel Metal Hydride (NiMH) batteries can handle frequent charging more effectively and are less prone to memory effect. They offer better performance relative to their size and weight, so they tend to be the battery of choice for heavy cellular users. This technology is newer than NiCad but most medium- and high-end phones now offer NiMH batteries.

Lithium Ion (Li-Ion) batteries are the top-performing batteries now. Incredibly lightweight and providing great talk time relative to their weight, they are also more expensive and in short supply due to the scarcity of the cells used in the manufacturing process. They have been used on a high-end phone models, but are becoming more common. If history is a guide, Li-Ion will become more available and affordable as the supply grows, more units are sold, and prices decline.
