Anyone have an issue with the stock battery? Mine apparently doesn't want to hold a charge past two days now....

Could just be a dud. Was curious if anyone had any problems with them.

Done any recent car audio ? I had a inline capacitor installed on my previous car and I had to use a trickle charger every few days due to the contant draw on the battery

Any aftermarket stuff added?
Tested load while car is off? Values?

Dead lol. I've had aftermarket stuff added, but I've moved it to my other car, and worked fine for a couple weeks.

"Dead?" What do you mean by that?

Did you check the impedance of the load the battery is seeing when car is off?
(Disconnect one battery terminal and use Ohm setting on voltmeter on + and - cable)

Haven't taken a multimeter to it, just noticed the car needing a jump after sitting a couple days. I'll look more into it.

Without knowing what you've added it may be hard for us to help you.

My 1st guess is someone wired something so that it didn't turn off with the ignition like it was supposed to...

bad battery or diode in alt...

Its your Android head unit!
Work backwords, unplug anything you have added rule it out.
The OEM Panasonic batteries are solid, rare to have a failure this early on.

Chris, let me know when you have time, I'll come over and we can pull fuses and hook my Fluke Multimeter up to the car...much more accurate than el-cheapo multimeter from Home Depot. My bet is you have a parasitic draw from your audio gear...maybe your amp's aren't turning off properly. Once a Lead-Acid battery completely dies once, it becomes damaged and doesn't hold a charge well anymore, best course of action is to find the parasitic draw first, fix it and then replace the battery.

He has an Android Head Unit and Hertz Crossovers and Amps, as well as a few smaller things.

I installed my audio gear in my other car for testing, it worked fine. The battery has died once from leaving my dome light on by accident.
