I plan to pop the batteries out, wire jumper cables to the leads and use it in my truck. Unless there's a reason this wouldn't work?
You can test it but I think you are going to be disapointed because it isn't going to work. While the inverters use 12v you are going to find that the batteries are in pairs wired +-+-. This doubles the voltage. Most higher voltage backups are really running on 24v which is why there is always 2 or 4 batteries. Only the very small inverters use 12v and use only 1 battery. This problem is easily fixed with a second battery. Instead of running the leads to your truck battery, you simply run the leads to a battery, then the battery to the truck battery. This actually will decrease the wear on your truck battery and is the best way to wire it even if it only needed 1 battery.
