Does a dead battery drain gas?
Without a properly charged battery, the fuel injectors may not add fuel to the cylinders as efficiently as they normally would.

Get the best Die Hard there is and forget about it. (there is other posts on the forum that address this, including part #s) There is a special charger for gel cells.

What happens if the battery on a Toyota Prius dies?
If that 12-volt battery is dead, the Prius won’t start, even if the main battery is fully charged.
