| Two battery in the Trunk, Which one to charge/jump?
Just wondering if any technician knows, if I have 2 battery in the trunk, one is a bigger normal automotive size battery, the other connected one is smaller that looks like a motorbike battery.
Anyone know which one I should jump or charge? The car is stuck inside a garage with a few other cars that needs jumping as well, so I can't bring it to the dealership without jump starting it. Car is a 2007 Azure.

if the two batteries are connected in parallel (+ to +, - to -), then it doesnt matter which one you jump.

As above, if you want the 100% correct answer: owner's manual. You can probably even find it on google.
That said, generally: On most vehicles with the Batteries in the trunk, there is usually a + terminal in the engine bay that is directly connected to the main cranking battery in the trunk. Pop the hood and look for a Red plastic cap with a + on it. You can pop that, connect the + from a booster pack to it, and a - to any piece of metal on the engine block.

Charge both batteries (one at a time) with a good charger (10A output or more, not some dinky trickle charger) for several hours each. For such an expensive car (Bentley) I wouldn't risk jump starting it unless you're 100% sure you're doing it right.
That or get it towed, though that might be difficult with dead batteries as you're going to have fun getting it out of Park or getting the steering to turn (if it's an electric lock).

the left battery is the main one. i suggest, disconnect the battery from the car, and charge it with a 1-2amp trickle. then reconnect it when it is fully charged.

Anyhow, problem solved. New battery is on its way ! Thanks
