Battery service

Hi guys

Ive switched from pc to mac for a year, and iam defetnly happy with my choice.

When I checked my battery, the battery status said that I need to have a service.
I am not quite sure what I should do, becasue now the signal is gone?

Do you have any reccomendations?

I am happy for every answers

Download the free "coconutBattery app" and post a screenshot of what it tells you here.

where did you "check" your battery? With some additional software?
My MBP is 2.5 years old, and I've never had any battery servicing done/needed.
Sometimes, all I do is calibrate the battery (let it drain fully and stay asleep for 5 hours and then recharge fully)
