Hi, I have accidently left the interior light on in my car and as a result the battery has died. The day after tomorrow I will have to drive about 450 miles in my car and am concerned that after I have jump started the car (which I plan to do tomorrow) the battery will just run out again while I am travelling in a couple of days. Is it likely to run out agan or should jump starting the car be sufficient enough for the car to run as usual? I don't believe there's any damage to the battery or the engine, I just think I've made a careless mistake leaving the light on. Thanks in advance :)

IF YOUR ALTERNATOR IS WORKING

IT SHOULD CONTINUE TO CHARGE YOUR BATTERY AFTER IT IS JUMPED

WHEN YOU DO JUMP IT

MAKE ABSOTIVLY SURE THAT YOU CONNECT THE CABLES CORRECTLY!

YOU MIGHT LET THE TWO CARS GET TO KNOW EACH OTHER FOR ABOUT 10 MINUTES, BEFORE YOU ATTEMPT A START, THIS WILL BUILD YOUR BATTERY UP SOME, BEFORE YOU DEMAND A BUNCH OF POWER ALL AT ONCE

PEOPLE GET IN A HURRY! RECKON THEY ARE SCARED THAT DANG TELEPHONE WILL MAKE A RACKET AND THEY'LL MISS SOMETHING AT "RUMOR CONTROL"!

EVEN JUST A MILLI-MOMENTARY TOUCH TO THE WRONG TERMINALS COULD SCREW THINGS UP AND COST YOU BIG TIME! NOT TO MENTION, THE INABILITY TO DRIVE IT (OR THE OTHER CAR)

IF YOU STILL FEEL UNCOMFORTABLE ABOUT THE CHARGING SYSTEM/ BATTERY

GIVE IT TIME TO CHARGE UP WHILE DRIVING (A COUPLE OF HOURS?)

STOP AT A POPULAR PARTS STORE, THEY CAN RUN A FULL TEST ON THE SYSTEM, THE SERVICE IS USUALLY A FREEBIE!

You do not want to rely on the alternator to fully recharge the battery. They are not built to do that. They are engineered to maintain a battery under normal use but when asked for maximum output for long periods they will often fail.

What you need to do is have the battery fully charged using a battery charger and then tested once fully charged.
