Rechargeable batteries and cells for devices that need fresh power often: remote controls, toys, camera flashes, torches, and wireless keyboards and mice. Our range has over 400 products, including ANSMANN, VOLTCRAFT, Panasonic and VARTA.
Most household rechargeables are NiMH cells in AA and AAA sizes. Lithium-ion cells go only into devices designed for them.
How to choose rechargeable batteries
Size and chemistry. Check which size your device takes: AA, AAA, C, D, 9V or a lithium-ion cell such as an 18650. A NiMH cell delivers 1.2 V against 1.5 V for an alkaline battery, so most devices work with either, but a lithium-ion cell must never replace an AA.
Capacity. Capacity is given in mAh, and a higher figure means longer running time per charge. It matters most in cameras, flashes and toys that drain cells quickly, and much less in a remote control or a wall clock.
Self-discharge. Ordinary NiMH batteries lose a noticeable share of their charge over a few weeks, even when unused. Low self-discharge cells, often sold pre-charged, hold their energy for months and suit devices you use only now and then.
Charger and cycle life. NiMH cells need a NiMH charger, and lithium-ion cells need one made for that chemistry. Manufacturers usually quote several hundred charge cycles or more, so rechargeables pay for themselves within months if you use them regularly.

Frequently asked questions about rechargeable batteries
How do rechargeable batteries differ from ordinary ones?
Rechargeable batteries can be recharged many times in a charger, while ordinary alkaline batteries are thrown away once empty. They cost more at the start but work out cheaper over many cycles. They pay off most in devices that use a lot of energy.
Can I use rechargeable AA batteries instead of alkaline ones?
Yes, in most devices NiMH AA batteries work in place of alkaline ones. They supply 1.2 V, so some sensitive devices may show a low battery warning sooner. If a manufacturer advises against rechargeables, check the instruction manual.
How many times can a battery be recharged?
Manufacturers usually quote several hundred charge cycles, and better NiMH cells last longer. The exact figure depends on the cell, the charger and how you use it. Cells last longest when they are not routinely drained completely or overheated while charging.
Do I need to fully drain a NiMH battery before recharging?
No, modern NiMH cells do not need to be drained first. They show very little memory effect, so you can put them on charge at any time. It matters more to use a proper NiMH charger and to avoid mixing old and new cells in the same device.
