You can charge the battery in situ, w/o the need to remove it from the trunk.

If you can get power to the car, just plug in the charger. I've done it countless times, in fact I the battery tender hooked right now.

You can also charge from under the hood, but I prefer right at the battery.

In any event, wait 16 min before disconnecting the battery: The trunk light will go out. Otherwise, you run the risk of scrambling one or more electronic modules.

Charge it in place.
