You don't use a battery charger- they only put out about 2 amps.
You need a regulated power supply like this one:
Some people have used a power supply similar to this one listed on eBay:
13.5V Regulated Switching Power Supply

I think you were referring to a battery tender when saying 2 amps.
We already took care of all the programming. We used the following which I've been using for a few years:

Held a steady 13.8v and updated entire car with no issues.

I just hook up another car via jumper cables! I get a perfect 14 volt with lots of amps from my gas powered, in-line 6, power supply.

LOOOOL. This is the type shops use. Sure I could spend $500-$800 on a BMW approved Schumacher but why would I need to? lol. It's already paid for itself 3x over. bike, lawnmower, car batteries when you're doing a flash that takes 10 hours or so you definitely need it! Or my friends MB gel battery that the dealer said was dead...i resurrected it with some additive and a nice juicy trickle
