I just left a product review for a battery I purchased for a 2015 MacBook, but I’d like to mention this here as well:

When replacing batteries that are adhered to the casing of a device, make certain that the battery is completely depleted before removing it. I didn’t do that and mine caught fire and exploded. I was carefully (but firmly) sliding a credit card under the old battery when it caught fire. That most likely wouldn’t have happened if I’d drained the old battery first. No damage done, but definitely was not a fun experience.
