Problem battery iFixit store.

I bought a new battery on iFixit store and I just replaced it.

After replace I left my Mac on charging all night for more of 12 hours for first charge.

This morning the battery was successfull 100%, although after about 2 hours or less of not using (stop mode) it is on 73%. I don't know what could be the problem.

What can I do to solve?

Here's @oldturkey03 guide on how to add an image to an existing question. Yours did not post: Adding images to an existing answer

Your battery is discharging, do you have the mag-safe adapter plugged in? If so, what color is the light on it?


No I didn't have the magsafe plugged in. Now I have the magsafe plugged in and the light is orange with the battery on 70% and Battery state on charging

The temperature is too high, 45°C now...


Just what is running 45 degrees and how do you know?

\Priming a New Battery

Not all rechargeable batteries deliver the rated capacity when new, and they require formatting. While this applies to most battery systems, manufacturers of lithium-ion batteries disagree. They say that Li-ion is ready at birth and does not need priming. Although this may be true, users have reported some capacity gains by cycling after a long storage.

“What’s the difference between formatting and priming?” people ask. Both address capacities that are not optimized and can be improved with cycling. Formatting completes the fabrication process that occurs naturally during use when the battery is being cycled. A typical example is lead- and nickel-based batteries that improve with usage until fully formatted. Priming, on the other hand, is a conditioning cycle that is applied as a service to improve battery performance during usage or after prolonged storage. Priming relates mainly to nickel-based batteries
