Energizer rechargeable C HR14 2500mAh batteries, pack of 2

This Energizer type C rechargeable battery (model HR14) has the same physical format as a standard alkaline battery, but uses NiMH (nickel-metal hydride) technology, allowing it to be recharged hundreds of times. I recommend it for all devices that require C batteries: electric toys, flashlights, portable radios, bicycle lights, and other household equipment.

Technical specifications and performance

The HR14 battery measures 50 mm in length and 26 mm in diameter, and weighs 69 grams. Its nominal voltage is 1.2V (standard for all rechargeable NiMH batteries), and its capacity is 2500mAh, providing a decent runtime depending on the device used. NiMH technology offers a better balance of performance and durability than older generations of rechargeable batteries, with a storage life of approximately 6 years when unused.

Compatibility and main uses

This battery fits any device designed to accept a standard C battery. Here are the most common uses:

• Electric toys and children's games
• Flashlights and portable torches
• Portable radios and audio players
• Bicycle lights and camping lights
• Digital cameras (external flash)
• Any household equipment that uses C batteries

Before using this battery, make sure your device accepts rechargeable NiMH batteries — most modern devices tolerate them without any problems, but some older models may be less compatible. I recommend checking the device manual if you are unsure.

Economic and environmental benefits

The main advantage of a rechargeable battery is the long-term savings. A standard alkaline C battery runs out after a few weeks or months, depending on usage; this HR14 battery can be recharged hundreds of times, drastically reducing your annual energy costs. Environmentally, you also generate far less waste by using rechargeable batteries instead of disposable ones. You will need a compatible charger (not included with this product) to recharge the battery — make sure you have one or can obtain one.

Who it is suitable for

Ideal for: Anyone who regularly uses devices powered by C batteries — parents with children, campers, cyclists, and photography enthusiasts. If you are looking to reduce your consumption of disposable batteries, this is an excellent investment. I consider this battery a sensible purchase for households that use C batteries several times a month.

Less suitable if: You do not have a compatible C battery charger, or if you use C batteries very rarely (once or twice a year). In that case, disposable alkaline batteries remain more convenient. If you are looking for energy storage solutions for other sizes (AAA, AA), I would instead direct you to our practical storage accessories, or you can explore other ranges of rechargeable batteries according to your specific needs.

A friend’s tip — Store your battery in a cool, dry place, away from direct moisture. If you do not use it for several months, recharge it approximately once every 6 months to maintain its long-term health.
