I checked codes on my 2013 Leaf S with 89000 miles. Since it is new to me I plugged in an OBD2 and used LeafSpy Pro. Some of the codes that cam up were showing low voltage, after doing some digging it looked like it may be time for a new battery. When I pulled the battery out it was dated 11/19 so it was pushing the 3 year warranty. It was a lead based battery. When I took it in to the battery place the scan showed it was good, but only at %50 charge. I decided to buy an AGM battery since they seem to be better for the leaf. After clearing all codes and driving around for a bit none of the codes came back. My question is....Should I be concerned that the old battery was only at %50 charge? I worry that something could be wrong with the charging system. I haven't noticed any problems with the car, but the auto parts guy got me thinking that maybe something isn't right. Then again...what does he know.
Sorry I don't have the codes. I'm new to Leafspy, and totally forgot to screenshot them to share.
