Duracell C Rechargeable Batteries 3000mAh NiMH (2 Pack)

Duracell C rechargeable batteries deliver 3000mAh capacity in a nickel-metal hydride (NiMH) chemistry that can be recharged hundreds of times. Each battery arrives pre-charged and ready to power devices immediately without needing a charger first. The Long-Life Ion Core technology maintains charge retention for up to 12 months when the batteries are stored unused.

These C-size cells suit high-drain devices including torches, radios, portable speakers, children's toys, camping lanterns and outdoor equipment where replacing single-use alkaline batteries becomes expensive over time. The 3000mAh rating provides extended runtime between charges compared to lower-capacity rechargeable alternatives. Each battery works in any standard NiMH charger, allowing existing chargers to be reused without needing Duracell-specific equipment.

The twin-pack blister contains two C batteries, each measuring 50mm height by 26.2mm diameter — standard C-cell dimensions that fit any device accepting C batteries. Duracell backs unused batteries with a 5-year guarantee from the purchase date, covering manufacturing defects and performance degradation during storage. The NiMH chemistry contains no cadmium, making disposal more environmentally acceptable than older NiCd rechargeable cells.

How many times can these batteries be recharged?

Duracell states these can be recharged hundreds of times. The exact cycle count depends on how deeply the batteries are discharged before recharging and the charging method used. Partial discharge cycles extend total lifespan compared to full drain-and-recharge cycles.

Do they come charged or do I need to charge them first?

The batteries arrive pre-charged and can be used immediately out of the pack without needing to charge them first.

What charger do I need?

Any NiMH battery charger that accepts C-size cells will work. You do not need a Duracell-branded charger — the batteries are compatible with all standard NiMH chargers on the market.

How long do they hold their charge when not in use?

When stored unused, the batteries retain charge for up to 12 months. This makes them suitable for emergency torches, camping equipment and seasonal-use devices where batteries sit idle between uses.
