Aldi Ready to Use Rechargeable Batteries

Aldi Ready to Use Rechargeable BatteriesAldi is advertising AA and AAA Ready to Use Rechargeable Batteries. These are in packs of two for AU$7.99. The AA size are 2000 mAh and the AAA 800 mAh. These appear to be low discharge cells, simialr to SANYO eneloop , Sony Cycle Energy and Duracell Pre Charged. The advantage of these batteries is that they hold a useful charge for about a year and are compatible with chargers and devices which use ordinary nickel metal hydride (NiMH) rechargeable batteries.

Pre-charged Nimh C Cell Batteries

The low self discharge AA batteries I installed in a String Trimmer seem to have lost their charge after just under a year. This may be because they were left plugged into a dumb charger (the batteries are supposed to be disconnected from the cgarged when the are charged and then hold their charge). Or perhaps a year is all that can be expected in a heavy duty application from these batteries. Sub C cells, which the trimmer originally had, should offer more power.

Tenergy are offering
Pre-charged Nimh C Cells on The catch is that they are only 3000mAh capacity. It is likely these are actually AA cells fitted into a larger empty metal cylinder to make them up to C cell size. Other C cells are usually 5,000 to 10,000 mHa.
