Batteries by Size

Eneloop is a new type of NiMH consumer battery developed by Sanyo, the world's largest portable rechargeable battery manufacturer. Eneloop features very low self discharge which makes them ideal for virtually all situations where alkaline batteries are currently used. Normal NiMH batteries provide much more power to high drain devices compared to alkaline batteries but they can lose most of their charge in a matter of weeks. As a result NiMH batteries are excellent for high power devices such as digital cameras however, unless charged shortly before use, normal NiMH batteries are generally unsuitable for medium to low drain devices because of their high self discharge, especially when use is infrequent.
