Title: 18 Volt Battery Pack......What's Wrong With This Picture?
Post by: snub on December 08, 2011, 11:33:15 AM: I took the 800MaH battery pack out of my drill to replace it with some 2500MaH batteries I got . I was attempting to replicate the way they were hooked up when I came across this slight problem as seen in the pic below. Seems one of the batteries was left out of the 'loop'. I can't figure out how this pack would even work. Might explain why the drill was a bit 'sluggish'.

Top Side. Battery with ? is the the slacker.

Assuming a nominal 1.2V for a nicad ... it was never 18V anyway ...

13 cells only gives 15.6V :scratch:

So, if it was Chineeeeeeese .. maybe, as they hold their currency artificially high ... they do the same with the Volt ???

If they have 13 cells, one as a packer ( ? ) 12 would be OK for 14.4V.

Dunno ??

Life is strange at times .

Quite how it works though, is anyone's guess...unless there is a connection in the case perhaps

I count 15......

13 in the first pic + two below=15...*1.2= 18volts...

Although 1.2v is a nominal voltage, my 4 cell radio receiver packs come fresh off charge at around 5.5v-5.6v

"RECHAREABLE"

I'm guessing someone else saw it before me with how closely everyone has been scrutinizing the photo, but man, I love chinglish.
