Commander not starting

[ErtsRide1]

I had it tested 3 times at 2 different locations and it tested fine everytime... what should I do

[ErtsRide1]

I am having it tested 1 last time at another location... this location tests then charges then tests so we will see what it says...


Update... tested OK

Stop testing it and replace it. If you get 4 years out of a battery you've beaten it into the ground. you've already got 5 years. It needs to be replaced and unless they are using some extra scientific specialty battery testing procedures (it took batteries plus 1 day after i dropped off my battery with them to figure out my problem cause it always tested ok and thats all they do is work on batteries) they won't know. Just get a new one. You'll see.

Just the fact that you put a charger on it and it started tells you it doesn't work.

Testing these batteries DOES NOT WORK !! I dont know why but Sal did some research and I think he can tell us why. Just replace it. My buddy just went through the same deal with his Volvo, screwing around with having to jump it every other day and having it tested at multiple places only for them to tell him the battery tested good. He bought a new one and all problems went away. We have had lots of guys here with the same issues and its always the battery.

I find it hard to believe that a bettery that was replaced in September of 2010( after being tested many times) is bad.

Alternator and battery tested fine across my hometown

I am really leaning towards the starter...

It starts and runs fine right now at this very moment...

I will see if it does it again and check in with my synopsis

I wouldn't rule it out. I took back a battery I purchased new in february this year in june. It too tested fine. It didn't work. If it were your starter why did putting a battery charger on the battery help it start? The starter is completely inependent of what you did with the battery charger. Just sayin...

The battery tests produce false positives ( good battery) do to the new design that relies on a mathematical equation to calculate if the battery is good or not. The old testers use to put a load test on the battery to test it and it was fool proof but change ushered in and now people are replacing part after part for nothing more then a bad battery testing good. The age of your battery is approaching the life expectancy of batteries in our jeeps anything over 4 years is a gift of good will and good luck. Not with standing that point on it's own putting a charger on and having your issue solved is basic 101 mechanics the battery is having trouble(why?). Were getting into that transitional period of weather again folks, cold nights warm days just reeking havoc on batteries and exposing all there weaknesses. This is the time of year that battery issues start flooding all the forums LOL. 3 years is a little early to have a bad battery but considering you put a charge on it and your problem went away leads you in two directions, alternator or battery. Alternator is a easy check just drop you meter on there and measure what it is putting out. The battery well, that's a different story. The only true way IMO to test it is to test it under a load...... No fancy math involved put a load on it and see how long it holds the amps period.
