Panasonic EY9201B 12-Volt 3.3 Amp Hour NiMH Pod Style Battery

I have two panasonic 12v drills - one about 14 years old and one about 8 years old. At the time of purchase they were the finest cordless drills made (see my review) - but time goes on, and other drills have caught up and surpassed the old Panasonics.

A couple of years ago I had the batteries rebuilt at the battery store with NiMh cells. It was disappointing - they never worked like they did before. They wouldn't hold a charge, and didn't seem to have as much power.

I wondered if they weren't really ever as good as I remember. I've moved to Milwaukee V28's as my primary tools.

I bought this battery and charged it up and immediately it brought my drill back to life. This is why I bought the Panasonic in the first place. Great battery.

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.

Excellent battery - works great and price was right. May be more expensive than a cheaper complete drill, but this is an excellent drill with great battery life.
