Default need help asap.. need to keep powered when removing battery

I have to remove both my battery and my alternator for load testing because my battery has been going dead, but I CANNOT allow power to be taken away for a second from my car. The climate control head units are faulty in the Riviera, and if the battery is disconnected too many times it fries it. So, I have to connect a nother battery up before disconnecting mine. Will anything bad happen if I connect another battery somewhere else in the car while having mine hooked up? Don't want to have 24 volts going through the car or anything . I'd probably just connect the other battery to my amplifier power wire/ground. not very big wiring should be needed because I won't be starting the car or anything...
just making sure this is o.k. before I do it. thanks!

Interesting problem....

Connecting two batterys should be ok.....

What about using a cap from a stereo install... I wonder hold long that would last..... 20mins or so...
Enough time to install another battery?

Jumper cable from another car. This will make it VERY touchy while disconnecting the alternator. Use insulated tools.

You can connect 10 batteries, and it should still be 12v.

I ended up using a battery from a lawn mower. Just need something to sustain the memory settings, climate control, etc while I removed the old battery overnight. I'm trying to find shops that will test the battery/alternator. They say their scanners can't do them for some reason. The battery is 980 CA and the alternator is 140 amps. Can't find ANYWHERE to buy a battery for this car except for from GM directly. The alternator I can find, but I don't know if I should go with the AC Delco or the Beck/Arney unit. The AC Delco is actualyl cheaper and has a lifetime warranty though through www.partsamerica.com so I might go with that one.

Optima Red Top for a battery 'Nuff said. Order one over the web if you have to. It'* probably the last battery you will ever buy.

Isn't there a device that plugs into your lighter that uses D-cells?

If that is the Riviera'* oem battery from 97, I would just replace it. But having the alternator load tested on the bench would be worth while.

I have seen some trickle chargers advertised that plug into the cigarette lighter to charge your battery, I think the one your referring to is only suppling a few volts to maintain things like stereo settings, clock, etc, which probably would've worked BTW.

Do you mean something like this? A 9 Volt unit from JC Whitney
