Digital Camera World Verdict

Rechargeable batteries have had a checkered history. They’ve long been cost-effective and convenient in some ways, less so in others. Unlike previous rechargeable batteries, Eneloop cells retain their charge over many months and even years, so they’re always ready to use whenever you need them. They’re long-lasting too, both in terms of capacity and overall lifetime. Eneloop batteries aren’t the cheapest around but, at Digital Camera World, we’ve been using them for years and love their 100% reliability and rock-solid performance. When we need to know we can completely trust a set of batteries for an important shoot, Eneloop is the brand we reach for.

Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

Eneloop batteries have been around since 2005, although they were originally made by Sanyo and later acquired by Panasonic in 2009. They were somewhat revolutionary at the time, solving a number of perennial problems suffered by rechargeable batteries. Older NiCad (Nickel Cadmium) rechargeable batteries suffered from a ‘memory effect’, so you’d have to discharge them completely before recharging them to retain their full capacity. Specialist battery chargers could do this, but you’d be in for a long wait.

Newer NiMH batteries had virtually no memory effect but tended to self-discharge over a few weeks, even when sitting in a drawer doing nothing. By the time you came to use them, they’d often have very little charge remaining or even be completely flat.
