I have Macbook Air A1370 (MacbookAir4.1, High Sierra)
I had to replace an original nearly dead battery with the replacement I bought on eBay.
I received A1495 battery instead of A1406 supposed for my Mac (even it was advertised as compatible)
When I replaced the battery the system became extremely slow, but as it was in another country it was very hard and costly to return/exchange battery.
'''Finally I found a solution.'''
You have to delete one plist file from your system.
You may find the solution here:

To be able to delete a plist you may have to disable SIP:

Saved me a lot of time and money :-)
P.S. I also tried to update SMC, but I didn't find a solution for High Sierra as an update mentioned earlier doesn't work on High Sierra and I'm not sure the SMC on my Mac is up to date.
