Will car battery work after sitting overnight?

My sisters car battery is dead after the lights were left on. The hood won't open because the hood release latch is broken. If the car just sits all night will it work in the morning?Will car battery work after sitting overnight?
Best to get the hood latch fixed, so you can check all under hood, but for emergency type fix if you have a spot light or a plug in that will fit the cig lighter you can use a 1 amp charger through it, but you have to wire it correct so the plus side is the center of plug and the minus wire is the side contact if you know what your doing this will work for you over night, the hood cable that broke can be opened by any mechanic, If you decide to charge your batt through the cigg lighter, make sure its low amp charger as to high amp can cause a wire to get hot and catch the car on fire, they do make 1 amp charger with cigg lighter plug on the end if you wish to buy one, P.S. sometimes a batt if its newer or in good shape will build up some during the night but not enough to start the car acid type batt will recover some on there own.
Nope. You're going to have to get creative and pop the hood somehow. Can you see the wires that attach to the release handle? If you can, use some pliers to pull on the bundle (or single cable, depending on the car). That should pop the hood. Otherwise, have it towed to your mechanic and have them a) fix the hood release and b) replace the battery.Will car battery work after sitting overnight?

just try to open the hood to replace the battery.
