Battery stuck on 7%

I recently installed a new battery into my 2011 13" macbook pro. It was working great for about a month, but then started acting weird.

Now, when I unplug the computer after a full charge, the battery will drain MUCH faster than the estimated time remaining. It'll go from 100% to 7% in about 2-2.5 hrs with extremely light cpu usage (light web browsing, only 1 window), even though the estimated time remaining after a full charge reads around 5-6 hrs.

Once it hits 7%, it'll stay there for about an hour or so without changing at all...eventually after an abnormally long time the charge will continue dropping.

I've tried reseting the SMC and recalibrating the battery, but it continues to do the same thing...my system info is saying my battery is in normal health with full charge capacity...

MacBook Pro (13-inch Early 2011), OS X El Capitan (10.11.5)

What brand is it? Sadly, a lot of 3rd party batteries are duds.

Where did you get your battery from and was it fitted by an Apple store or authorised re-seller ... or yourself?

Ordered off amazon, put it in myself. Seemed to be working really well for a little while...probably just a hardware issue?

Hello jhkim90

Apologies if this comes over rather negative but although your machine was out of warranty, if it had not been opened up before, Apple could have changed your battery for you ... and inserted the correct item.

Unfortunately, now you have taken this course of action, they are most unlikely to want to touch it. I guess you have little option but to put up with the situation or take it to an unauthorised outlet for assessment.

The general consensus on these forums by veteran participants is that NuPower batteries and Anker batteries are the best third party options for MBPs. There have been too many tales of woe from users purchasing 'bargains' on ebay and other sources which turn out often to cost more in the long run.

Ciao.
