Good Evening I’ve been have issues with my car drains battery once it’s been sitting for a couple of days. I’ve done the parasitic draw test and I’ve been getting a reading of -0.22 amp. I pulled all the fuses and the one that gives me a zero draw is fuse #23 50A/50A +B IG1 Main/ Power Window. My Battery Voltage when I first started test was reading 13.28. Any help will be appreciated!
.50 mA and below is an acceptable draw. At that rate a battery can sit approx 4-6 weeks(lot of other variables impact this) before discharging.
Your draw is well within range.
The battery should read no more than 12.7v maximum while sitting and not being charged. If that reading is correct and the battery had not been loaded in the last hour,Id say the battery is bad.
However, since I do not recognize your meter ,I would try another meter just to double check.
(Im not saying your meter is bad,I simply do not recognize it and therefore the quality is suspect to me.)
