Service battery

我部macbook pro late 2011 15 吋 无啦啦 service battery 左， 但个cycle 只系75 。 有咩解决方法？

Do you connect the MacBook Pro to the power all the time?

The Lithium battery needs to release and then recharge to maintain its life. Charging it all the time will make the battery flat and die. The battery life of MacBook Pro can reach 1000 battery count, or 2-3 years recharging cycles.

(FYI, an iPhone can hv 500 battery count, or 1.5 year life, or just when the warranty expires, so buying the Apple Care before expiry is important).

So, time to change for a new battery. If u are out-of-warranty, then u can go to ShamShuiPo Golden Shopping Center and ask to replace for a new battery. Do ask to replace for a real one, not the substitute one to avoid explosion.

It has been almost 3 years, so I don't blame for that.

But you might want to reset the SMC first, GL.
