Default battery won't hold the charge please help

hi guys i was stupid that i put my headlights on and left it on for the whole night, ofcourse i had to jump it in the morning but then other that day when i try to start it up it won't start. today i drove 1-2 hours which lexus tech told me to do , he said idle won't charge the car and after 3 hours i try to start it, at the first 2 try it didn't the third crank did it. is my battery dead? it seems like it won't hold the charge., what should i do? if i let autozone recharge it ( free ) will i need to re set any settings???

ps. if i turn off engine and restart it even after a minute it will start , it just loses power after few hours , all my auto settings and accs are turn off

How old is the battery? Did you check the fluid levels?

It sounds like the battery was stressed and its time for a replacement. Take it to a dealer and have it tested. Some car parts stores will also do a load test for you.

Yes, you will likely need to reset several things. They are all in the manual but the automatic windows, rear lift gate and sunroof come to mind.

Get a battery charger/tender, they are not expensive, $40, a worthy investment. Then charge it overnight. Do you know how to use a multi-meter?

If the battery isn't the problem maybe fuel pressure is bleeding off. When you start it the first time and doesn't start it is priming the system. I would think battery but never know

always remember also with hybrids there is much more use and wear on the battery. you may buy an 84 month battery but in reality, because of the hybrid, you should only expect 36-48 months of actual use. when you replace, buy best deep cycle you can, i'd suggest the high end Optima battery. got mine at advanced auto parts. found 20% coupon online and bought online. picked up in store and they installed for free. $180 battery paid $140.

the simply reason for this is that on a normal engine the battery helps you start the car but then the engine and alternator supply power. with the hybrid, until the engine kicks in, it's all battery power. so in the end, for shear peace of mind, replace your 12V battery every 3 years.

Agree, these things do wonders and getting even a cheap multi-meter can also help. I got my parents one that you can charge up and then keep in their vehicle (particularly during winters) so they don't need to take the battery out of the car, but just attach to get a quick jump.
