Revived a salvaged 2010 MacBook Pro and the computer sprung to life after charging. The original battery would not hold a charge for longer than an hour. With this battery, the MacBook keeps a charge for 10+ hours of continuous use, and a few days on standby. Best battery for the price if you need to revive a 2010 Macbook Pro

After searching through filtering only high review products and evaluating Overall value, quality of product, materials used, and battery type technology. I chose Battery Ninja.Worth mentioning- for the install, make sure have great lighting and pay attention to detail when disconnecting the ever so small ribbon cables for the touchpad and battery bms connections.MacBook monitors the battery's voltage, current, temperature, and state of charge (SOC).Safety and ProtectionThe BMS plays a crucial role in ensuring the safety and longevity of the battery. It prevents overcharging, over-discharging, and overheating, which can lead to battery degradation or even fire hazards.Preventing Bad Batteries from Working:If the BMS detects that a battery cell is faulty or has degraded significantly, it may prevent the battery from being used or charging completely, or it may limit the maximum charge level to protect the system.Battery Health Indicator:You can often check the battery health status in macOS by holding down the Option key and clicking on the battery icon in the menu bar.

Works fine in my laptop, about 5 mins and it's fully charged, great for the price.

Easy to install; however, the enclosed directions do not match up with an apple airbook. Installation was much easier than the instructions. I would recommend a video.

This was an excellent choice as it fit exactly as described. It was a snap to put in. And charge the battery.You can’t go wrong with this product just take your time. I repeat take your time. There’s a lot of delicate screws that need to be aligned and tightened one more time…… TAKE YOUR TIME!!!

Instructions are a joke.

Easy enough to install, works great so far

pretty happy with the price and quality of this battery. Only negative thing was that it didn't come with any instructions and/or adhesive solvent. Not a big deal as I was able to use IPA and instructions which are available online. Overall the process was a breeze (I am not handy with electronics) and the battery was detected my macbook without any issue.Tool kit was very handy in removing various screws and back panel.
