Uh, yeah don't take a chance without the Lithium trickle charger. I didn't put one on my M4 and it sat for about 2 months. Wasn't planned, just got busy and didn't drive it for awhile.
Dead Battery, dead as a doornail. 0.43V and can't revive not matter what I try. CTEK won't recognized it as a valid battery anymore and tried a couple of internet tricks to bring it back to life. Don't want to push my luck anymore. Supposedly they can blow up / catch on fire if they are too far gone and you try to revive by doing stupid stuff to it.
Fingers crossed on warranty coverage for new battery, but not holding my breath.
