Bigger niche for small batteries
Batteries have improved dramatically in the past few years. Disposable, nonrechargeable batteries, for instance, now store more electrical power and have longer shelf lives than ever before. Moreover, rechargeable batteries can now operate reliably at high temperatures and for as long as 10 years. New chemistries based on lithium have made many of these improvements possible. Some advances have been aimed at improving miniature batteries like those found in watches and hearing aids. Disposable battery technology is even being applied in back-up power sources for volatile memory. Battery life in some new disposables is long enough - on the order of several years - that disposable batteries are sometimes more desirable than installing rechargeable batteries and the charging circuits they require.
