Description

The JCB AAA HR03 is a pack of four rechargeable NiMH batteries, each rated at 900mAh and 1.2V. The batteries arrive pre-charged and ready to use straight from the pack, providing immediate power for wireless mice, gaming controllers, remote controls, digital cameras, torches and other AAA-compatible devices. Each cell can be recharged up to 500 times, offering a reusable alternative to single-use alkaline batteries.

Designed for household electronics and moderate-drain applications, the 900mAh capacity sits between standard 600-800mAh rechargeables and higher-capacity 1000mAh+ cells, balancing runtime with the number of charge cycles the cell can sustain over its lifespan. The NiMH chemistry holds charge better than older NiCd cells and contains no cadmium, reducing environmental impact when the batteries eventually reach end-of-life.

The four-pack format suits homes with multiple wireless devices or allows you to keep spares on rotation whilst one pair is charging. Rechargeable AAA cells fit any device that accepts standard AAA batteries, but users should note that NiMH cells deliver 1.2V rather than the 1.5V of alkaline primaries, which may affect runtime in some high-drain devices. A compatible NiMH charger is required and sold separately.

Frequently Asked

How many times can these batteries be recharged?

JCB rates these batteries for up to 500 charge cycles. Actual cycle count depends on how fully the batteries are discharged before recharging and the type of charger used. Shallower discharge cycles and smart chargers that avoid overcharging can extend the usable life.

Do they come with a charger?

No. A compatible NiMH battery charger is required and sold separately. Any charger rated for AAA NiMH cells will work, but JCB-branded chargers are available if you prefer to match the battery range.

Are they pre-charged?

Yes. The batteries arrive pre-charged and ready to use immediately. Charge level on arrival is typically 70-80% of full capacity, sufficient for most devices to confirm they work before the first full recharge cycle.

Can I use these in place of standard AAA alkaline batteries?

Yes, they fit any device that accepts AAA batteries. However, NiMH rechargeables deliver 1.2V compared to 1.5V from alkaline primaries, which may result in slightly shorter runtime or dimmer output in some high-drain devices like camera flashes or motorised toys. For most household electronics the difference is negligible.

Shipping & Returns
