This is the replacement technology for nicad, although from experience not as durable or rugged. However, greater capacities are available from standard size cans.

This technology is and always has been the most durable and rugged of all battery technologies. Unfortunately, due to government legislation, it is no longer allowed into retail markets, however, it is still available for industrial and commercial applications. Used mainly in applications needing voltage stability in any conditions, giving reasonable life, performance and pricing.

Basically a long-life version of an alkaline battery. These batteries carry an extremely extended shelf life and a wider operating temperature range. Lithium batteries are non-rechargeable.

This technology is the modern choice for mobile communications devices. The design and safety constraints usually dictate this technology is only viable for large quantities. However, a range of “standard” lithium-Ion packs are becoming more readily available.

Alkaline batteries are widely used in industrial applications usually where mains power is not available or practical. They may be used for the prime function or as a secondary or memory backup. Alkaline batteries are non-rechargeable.
