Service Battery Warning, what to do?

Hello, I have a 2011 MacBook Pro that I bought from someone recently. It arrived full of data, but luckily no iCloud, so I booted into Recovery Mode, restoring the stock MacOS 10.7 Lion. I noted that while in High Sierra, the battery had around 200 cycles and was "Normal" with a maximum capacity of around 4500. A minute or two after MacOS Lion installs, the battery is reported as "Service". I also would like to note that when checking with coconutBattery, it seems that the battery was replaced with another genuine Apple battery in 2014. Any thoughts and tips?

Earlier Mac models

Hi,

Probably original battery is no longer available from Apple, though you can get third party battery, actually, although I checked at Amazon America, they are sold out, however Japanese Amazon carry them.

I'm not sure where you are, though try check it at your country Amazon or any other similar shops.

After updating to High Sierra, for some reason there now is no warning, and it reports the battery as normal. coconutBattery says the battery is "Good". I assume something changed with how macOS reads the battery? Could this bug be because my battery was replaced with a newer one and that maybe macOS Lion was just confused?

Hi,

Reading battery condition is analogized, It could be possible High Sierra is better reading battery condition.

You'd better read battery condition regularly anyway.
