which book has lights on the battery?

okay i saw a picture of a macbook's battery (not sure if it was a macbook, or macbook pro, or if it was an older model).

i think it was like 3 or 4 small lights on the battery, that showed how much charge the battery had. . .hehe, it's a small detail, but it's brilliant.
just wondering if any of you can let me know which book used the battery (or if it might have been a modded battery?).
thnx.

I thought all of them had that - mine certainly does and that's a summer 2006 first gen MacBook.

Mine does as well and it is a MBP.

so it sounds like both the mb and mb pro has it. sweet! hehe it's all the small detials that the books have, as well as leopard has that's really drawing me to get a mac.
thnx.

The only small detail difference is that the MB does not have the light up keyboard, only the Pro has that.

Apple has been doing the light on the battery for a long time. I have a G3 iBook that has lights on the battery.
