New VERY OLD Stock batteries The battery is what is claims to be. Genuine Apple (fallen off the back of a truck, out the side door of the factory, etc.) and new/unused BUT it is very old stock (over 6 years old). Mine was older than the laptop it went into. Since battery chemistry degrades with time, being unused does not make it like new. Cad jewelry design software for mac. Mine immediately dropped to 87% of original capacity on a calibration discharge and has only come back to 91% upon its first recharge. This would be fine if this stayed at this level since it would still be an improvement over my old 625 cycle battery BUT my experience with old batteries says that this is likely to continue to degrade with use pretty rapidly as age catches up quickly to with this old thing.

It is not clear that there are ANY significantly newer genuine batteries for this era of MBP and all sellers' look like the same NOS that the factory is clearing out. As ever, you get what you pay for and there are no super bargains out there. $200 installed from Apple should at least last 5+ years and be warrantied.

These can't be easily returned since installing them (with the required adhesive strips) ruins them for reuse.

Hello, I'm a owner of MacBook Pro Retina 13.3 inch, model A1425, part number Z0PW0000Q, early 2013, and I have two questions. Is there possible to make a memory upgrade?

I currently have 8Gb DDR3 1600Mhz and I think is more than enough for the moment, but is there a possibility to go for 16Gb of RAM or more? I just have 18 cycles on my battery but if is breaking, is there a possibility to replace the battery easy, at home? Or is glued on the body as I read on some other internet pages? Samyaza wrote: 1.
