Panasonic Eneloop Pro AAA Batteries (HR03) - 4 Pack

Eneloop Pro is the high capacity rung of the Eneloop ladder, and this listing is a box of four AAA cells. Each one is a nickel-metal hydride cell, and the retail pack prints a minimum capacity of 930mAh while the cells themselves are marked 900mAh, so we quote both figures rather than pick one for you. They come precharged and ready to use, which means the first set can go into a device straight from the box instead of spending a night on a charger. The pack also states the cells can be recharged up to 500 times.

Capacity is the reason to choose Pro over a standard Eneloop, and it tells in the devices that pull hard on a cell: a camera flashgun, a radio microphone, a head torch, a games controller, or a wireless mouse that otherwise eats through alkalines. AAA is also the size that hides in the awkward corners of a house, in remote controls, digital thermometers, doorbell pushes and children's toys, and a box of four covers two devices taking a pair each or one device taking four. A NiMH cell is nominally 1.2V against an alkaline's 1.5V, but it holds its voltage flatter through the discharge rather than tailing away steadily.

The pack makes two claims about storage that are worth knowing. The cells leave the factory precharged with solar energy, and after a year of storage the pack states that 85 per cent of capacity remains. That is what makes a rechargeable useful as a spare rather than only as a working cell, because a set left in a drawer is still worth reaching for. The packaging is plastic free and printed on FSC certified paper. We sell the box of four as one unit with no multiple to meet, and it sits alongside our Eneloop AA cells and the Eneloop BQ-CC63U charger, which handles eight AA or AAA cells at a time.

Do I need to charge them before the first use?

No. The pack states they are precharged and ready to use, so the first set can go straight into a device from the box.

How many times can each cell be recharged?

The pack states up to 500 recharges per cell. After that you are replacing four cells rather than the many disposable sets they stood in for.

What charger do these need?

Any charger rated for AAA nickel-metal hydride cells. Our Eneloop BQ-CC63U takes up to eight cells at once in AA or AAA size.

How is Eneloop Pro different from standard Eneloop?

Pro is the high capacity line. This pack prints a minimum of 930mAh, and our standard Eneloop AAA four pack is listed separately if you want the regular cell.

Will they fit anything that takes AAA?

They are a standard AAA cell and fit any AAA compartment. The nominal voltage is 1.2V rather than an alkaline's 1.5V, so check what your device says about rechargeables.

How many cells come in the box?

Four. One purchase of this listing gives you four AAA cells, and there is no minimum multiple to meet on the order.
