Hi guys,

I got a notice saying that I should service my battery.

My MacBook is 37 months old and coconutbattery says battery life is 67%.

I haven't calibrated the battery in a while. Maybe if I do it the message will go away?

Anyway, I'll do it tonight probably. If nothing changes, I guess soon is time to buy a new one... :(

Thanks a Merry Christmas!

Doubt you can Fix it but give it a shot

It probably won't help, but you could try resetting the SMC. Calibration is unlikely to help. Time for a new battery.

This should answer most, if not all, of your battery questions:
 
I got the message on my old computer and it went away after calibrating the battery. Definitely worth a try.
 
I think this usually comes up when the battery goes below 75% health. Three options:
- ignore
- buy a new battery
- buy a new laptop

As long as the shortened battery life is not a problem for you, you can just ignore the service request.
 
Yesterday the service message disappeared as the battery life came up to 80% but now it went down again to 72% and the message is back.

So, to contact the Apple Support to try and get a new battery from them, should I go directly to an Apple Store (if I can find one close to me) or should I contact them?

Am I allowed to use my recently purchased iPhone 4S to have them call me through the Express Lane?

What's the best way to proceed?

Thank you all!

@OP: How many cycles does your battery have & do you have AppleCare?

No, they don't have AppleCare, as indicated in their first post. Their battery isn't covered, regardless of the number of cycles.
 
I sometimes left my charger charging after 100% for couple hours, does that mean my battery life will degrade?

No, it won't damage the battery to leave it plugged in after you reach 100%. As long as you're unplugging it and actually using the battery a couple times a month you should be fine.

No, this hasn't been true in laptops for quite a few years, Li-Ion batteries used in laptops these days do not require any particular care apart from actually being used once in a while. Use your MBP on the couch once a week and you'll be perfectly fine.

When your battery is fully charged, it stops charging, even if you leave it plugged in, so no, it won't hurt it. What degrades battery life quicker is if you leave it plugged in all the time, never running on battery.
 
I did the calibration and the SMC reset.

Nothing helped.

It's either time for a new battery or new laptop...
