1 AAA Fujitsu - 750mAh rechargeable HR-4UTC

Fujitsu is one of the best rechargeable Ni-MH battery currently available.

It can now be charged and discharged even up to 2100 times. After charging, up to 90% of the charge remains after 1 year of storage; and up to 70% of the charge remains after 5 years of storage. So, even years later the batteries are still charged. This in contrary to 2700+ mAh Ni-MH batteries, that often loose most of their charge within a couple weeks. Fujitsu batteries are therefore a good option for devices that use low amounts of energy over a long period in time, such as remote controls.

One of the main features of Fujitsu is the higher voltage level. Many applications switch off or show the low battery signal if the voltage is lower than 1,1 Volt. A traditional Ni-MH battery will lose its voltage constantly and runs under this critical level very soon. Fujitsu batteries however will keep the voltage level over 1,1 Volt for a long time. This makes sure that the flash of a photocamera is ready for the next photo sooner than with most other rechargeable batteries. And much faster than when you use Alkaline (primary) batteries.

Another great advantage of eneloop is its good performance at low temperatures. Especially when temperatures drop below zero degrees Celsius will Fujitsu batteries perform better than the competition.

You can charge Fujitsu batteries with a normal Ni-MH battery charger.
