Causes of battery Power drain (off Topic)
I suspect, but do not know for sure, that an old car I have (91 Lexus ES250) maybe somehow draining power from the battery when it is not running. It's not driven very much at all. Is there a way to find out if battery power is being used when the car is just sitting in the carport. I know it has a secutity system, and a clock that never shut down.
It had a battery in it that was about 4 months old. I went away on a trip that lasted about 3 weeks, and maybe another week passed before I needed to use it, but when I opened the door not even the interior lights came on. I have a charger and tried to recharge it but the charger gave me a code that said it was bad.
The battery tested bad at the store where I bought it, and they replaced it. The trouble is that the battery they replaced was a replacement itself for another battery from that the same car. That one was constantly going down to where it wouldn't start the car (Which was why I bought the charger) and it eventually tested bad.
