Batteries in our range cover chargers, rechargeable cells, button cell and photo batteries, disposable batteries and a small selection of lead-acid batteries, for households, workshops and business equipment. Over 1800 products are listed, with leading brands including VARTA, ANSMANN, GP Batteries, Energizer and Duracell.
How to choose batteries
Size and type. Check the code on your old battery or in the device manual before anything else. AA, AAA, C, D and 9V cells are not interchangeable, and button cells such as the CR2032 differ in diameter and thickness even when they look alike.
Chemistry. Alkaline batteries suit low-drain devices such as wall clocks and remote controls. Lithium disposables cope better with cold and hold their charge in storage for years, which helps in smoke alarms and outdoor gear. Rechargeable NiMH cells are the sensible option for devices that drain batteries quickly, such as game controllers, cameras and torches.
Capacity and charge cycles. For rechargeables, capacity in mAh tells you how long a cell runs between charges, while the cycle rating tells you how many times it can be refilled. Low self-discharge cells keep their charge on a shelf, so they work well in devices you use only now and then.
Charger compatibility. A charger must match the cell chemistry and size. A basic model charges pairs of AA and AAA cells, while more advanced chargers handle each slot separately, show charge status and stop when cells are full. Our range has more than 300 chargers, so it is worth comparing the number of slots and supported sizes.
Voltage and special uses. NiMH cells deliver 1.2 V against 1.5 V for a fresh alkaline, which most devices tolerate but a few sensitive ones do not. Lead-acid batteries serve a different purpose: backup power and larger equipment, where capacity and terminal type must match the original.

Frequently asked questions about batteries
Are rechargeable batteries worth buying?
Yes, if the device uses batteries regularly. A NiMH cell can be recharged hundreds of times, so it replaces many disposables over its life. For devices that rarely need power, such as a smoke alarm or an emergency torch, lithium or alkaline disposables are often simpler.
What does CR2032 mean on a button cell?
CR2032 is a code for a lithium button cell with a 20 mm diameter and 3.2 mm thickness. The C stands for lithium chemistry, the R for round shape. Other cells such as CR2025 have the same diameter but are thinner, so they may not fit securely.
Can I use rechargeable AA batteries instead of alkaline ones?
In most devices you can, as AA rechargeables have the same physical size. They supply 1.2 V rather than 1.5 V, which is fine for cameras, toys and controllers. A few devices that are sensitive to voltage may show a low battery warning sooner than expected.
Can any charger charge any battery?
No, a charger must support the cell chemistry and size. A NiMH charger is intended for NiMH cells, and should not be used for standard alkaline batteries unless the manufacturer states it is safe. Check the supported types in the product specification before buying.
