I had recently purchased a used Lexus ES 300 (2002 model) from a dealer, may be 4 months ago.
Just 2 days ago, when I was trying to start the car, it didn't. I had to do around 4-5 time and then it finally started.
When I opened up the bonnet it had a Panasonic battery , not sure if its was the factory installed battery.
There was a sticker on it which says "maintenance free"
Questions:
1) What is this maintenance free mean ?
2) Can I replace the battery with any other walmart battery for my Lexus ES 300 ? or does it have to be any high power panasonic battery only ?
3) Usually how long does batteries last ?
4) Can I replace it myself or best way is to get to walmart or autozone and have it replaced there ?
5) Are there any tools or devices which will tell us the life of the battery ?
