Can i use 12volts to charge my pro-106 without damage or does it have to be 9volts.Thanks
It is made to run off and charge from 9 V DC . More than likely you will let the magic smoke out......
Let me share my strong opinion. $500 scanners (even $300 dollars scanners at sale price), make rather expensive battery chargers. One cell explodes, and you lose a rather large investment.
May I suggest you use my method?
You buy two sets of Powerex Maha batteries, and a conditioning charger. You keep a spare set charged at all times. You change them when needed, and don't charge them with your scanner.
Now, I understand not everybody can rush out and buy the extra gear, and if you can't fair enough. But if you possibly could, you would be well served. By the way, these batteries last forever and ever. They blow everything else I have tested out of the freakin' water. Just my two cents.

Where have you found to have the best deal on the batteries and charger? And by "best deal" I mean price and service. The best price isn't always the best deal.
