Caution instead indulgence

I have this battery found in a me surrendered, defective Macbook Pro 1.1 in 2006 and again just checked prior to the drafting of this review, if it is indeed the battery offered here - because I have no wish, as GRS battery pack incorrectly a to miss bad review. Especially not when a company is trying to offer an affordable alternative to a very expensive Apple original battery. This is more than commendable and of course tempting for owners of older Macbook Pros.

Unfortunately, the operation of a Macbook Pros with no battery is in fact anything but recommended. In this case, the CPU is throttled massively despite network operations. It is the proud owner of a Macbook Pro to buy so in case of a battery defect simply forced to buy a new battery and clear - come here as manufacturers GRS battery just right, because Apple's original battery is very expensive.

Unfortunately I can not say anything positive about this battery here. After repair of the Macbook Pros (HDD defective RAM defective, braised cable) and the successful recommissioning immediately fell on - there's something wrong. But first to the positive side: After read almost virginal 20 charge cycles, the battery built 100% capacity. That's it.

The negative side: the MacBook Pro produced in battery mode high frequency sounds, the battery is truly remarkable hot, Coconut Battery was not constant and permanently read the battery able to OSX not. Fit - unobtrusive bad a start only on battery power was not possible. Since no calibration something or the application of the usual tips and tricks availed.

The worst: The Macbook turned abruptly without warning, completely made - even when the battery to 100% and the computer hung on the network. So is not to think about working safely.

Meanwhile, I have an original Apple battery installed (grudgingly) and all Aufälligkeiten thing of the past. Noteworthy: I hear no longer the fan. The battery of GRS definitely has taken care of an unfavorable heating of the system. What I therefore can not and wants Exclude: Possibly this battery was originally responsible for the failure of the hard drive and RAM.

Of course, not every battery behave just like the present to me. But I would advise you to claim the product immediately when any of the above problems. Even if the computer appears a few days at a time to run perfectly. Do not wait.

The trend: Stay away!
