These two 4GB 1333Mhz DRAM memory modules may be compact in size, but they come with boundless benefits. Designed with the MacBook Pro Sandy Bridge Unibody in mind, they consume less power and are more efficient than stacked modules. They're also compatible with the latest firmware, so you won't lose precious speed.
Over time, your laptop battery continues to lose its ability to charge, making it difficult to use it anywhere there isn’t a power source. A new battery can lend a new lease on life to your laptop, giving you the flexibility to work or play on the go.
Compatible & Reliable
Ramjet Mac Batteries have been designed and engineered to fit seamlessly into your Mac just like the original battery. We’ve rigorously tested and certified our batteries to make sure they work perfectly for you, just like we’ve done with our industry-leading Mac Memory and other products since 1996. Ramjet batteries also come with LED charge-indicators and provide longer charge times than your original battery ever did.
