Hello folks, I'm new to the forum. Tried looking my issue up in the old threads but didnt find exactly what I was looking for.
My battery went dead in a parking lot after the dummy driver of this car (yours truly) left the lights on. No problem I thought, so I'll get a boost. No biggie. I get a boost, Lexus starts, I'm happy. We remove cables, I shift it out of gear and Lexus shuts off. Ok thats weird. Never seen that in my life. Now its not even starting from a boost. Wow. Not sure what to think at this point. I get a boost from a truck instead, with better cables. Lexus starts, and I'm on my way. I probably put about 15 minutes of driving on the car before parking it in my garage and hooking up to my battery charger. Electronic battery charger showed 50% capacity when I plugged it in, and I left it for an hour or so at 15amps, which normally will charge my Acura TL to full if it's similarly low. I look at the charge level after around half an hour and its at 70%, which is slow, but whatever. I look at it again half an hour later and it's still at 70%, so I unhook it suspecting a problem. Battery is hot to the touch. Vehicle starts, again I'm on my way, and I end up leaving it at work and taking a different vehicle home. When I go back to work the next day, the Lexus wont start. It clicks, but doesnt even attempt to turn over.
This got me wondering if maybe it's a special type of battery, maybe a different than normal voltage, or something along those lines, but from reading past threads and seeing a guy talk about replacing it with one from sears or costco for $50, this doesnt seem likely. However, I've never had trouble boosting or charging a car before, so I figured I'd try and draw from the past experiences of people who know more about these cars than I do, which is what brings me here. Any help on this matter will be sincerely appreciated. Thank you.
PS - It's a 2005 ES330.
