NinjaBatt A1466 Battery for Apple MacBook Air 13″ (Mid 2012, Mid 2013, Early 2014, Early 2015,2017) A1369(Late 2010, Mid 2011 Version) A1405 A1377 [7200mAh/55Wh/7.6V]

Perhaps 15 minutes to swap the batteries. I replaced the bottom and plugged in the charger and immediately heard the chimes. Everything you need is in the box. Be sure to wear the rubber gloves to avoid static electricity.I've been opening up Macs since the early days of converting a 512 to a Mac Plus so it might take a little longer for you.

I’m back up and running! Included everything needed and thanks to YouTube tutorials the replacement process was quick and easy. Can’t believe I waited this long to do it myself and ashamed I was going to take it to the store and be charged a lot for a fix so simple.

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

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.

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.

Appears well made and actual good instructions

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!!!
