Max 2k2 battery

If a battery discharges beyond a certain threshold, it is very difficult to recharge it (or that is my understanding, at least). Interstate make excellent batteries and I would highly recommend one of those as a replacement for your Maxima.

Pretty normal for today's cars with all the electronics. Batteries don't like the run totally flat. It's not uncommon for them not to come back.

When all is in top condition, this should not happen... Measured leakage should be maximum 0.05Amps. This means every hour bites that amount of capacity from battery.

The leak -calculation, how long healthy batt lasts, seems 'simple', however has lots more nuances than this... but heres the basic:

As your battery has 60A capacity, standing 1000 hours means THE END with mentioned leak of

My Maxima measured leak current is now 0.01Amps when alarm is ON. That means 200days standby...

Wassup Leak: Myriad reasons from inadequate charge, to -any- accessory leak voltage to ol battery.

Note: I have currently a cutoff switch on radio/light dimmer circuit ... which leaks VERY LITTLE = 0.14Amps. Two months would definitely kill the batt.

Check this and measure your leak:
