Grunty [Posted on 2002-12-26]
I received my 3.5Ah EY9201 NiMh 'G' battery for Christmas, so I haven't been able to give it the test of time (hence only 4 stars) but it's a grunty looking battery.

It weighs 820g (1lb 13oz) compared with only 700g for the 3Ah 'N' battery; and 520g (1lb 2oz) for the 'C' battery (but then a charge should last 3 times as long as the 'C'). To gain the extra capacity the cells are almost square, giving them a larger cross-sectonal area. This leaves very little space inside the battery pack - hence the screws on the outside.

I've read of the previous NiMh 'N' battery packing up in as little as seventeen months. A friend has had two for nearly two & half years without trouble, but he never lets them run down. If he uses them at work during the day, they go straight onto the charger when he gets home. Maybe that's the secret to long life for NiMh batteries.

The weight and the 55min charging time would be the only negatives.

Buy it without reservations. [Posted on 2005-01-05]
After using this battery in my impact driver for six months, I can honestly say I am very glad I bought it. It outlasts the 3.0Ahr NiMH battery that came with the driver by 2X or more and provides impacts that are more powerful. Now I only use the 3.0Ahr battery while the 3.5Ahr power pack is charging. Well worth the extra money.
