it's your alternator, and it's defective. have it checked by a professional.

when the battery charge light turns on in your dashboard, that means your alternator is not charging. a defective battery won't turn on the battery charge light. It'd just hard/won't start.

You can drive it if you have to, but turn off all unnecessary devices (a/c, radio). your battery is shouldering all your car's electrical needs, and depending on the battery, it can last you. you need to bring your car to a decent service center, so they can advise you better on what to do (your alternator might still be reparable).



Otherwise, don't use your car too often. Drive only for emergency purposes. You don't want to stall anywhere.
