not too bad

it fit well and quality is good, however, the plastic insert snaps not enough for my mug guard and one is defective.

Lithium should become the standard Tesla car 12 V battery

I hope the battery lasts for four plus years

I forgot about the frunk light and emergency unlock wires.

I have to pull the bucket out again to find them. Maybe a long string with a lassoed end would have prevented this from happening, if I could have tied it to the wire and strung it through the plastic bucket to keep it connected. Having long sockets would have made the removal of the bucket easier.

The battery itself seems to be terrific, but for my 2013 Model S getting the old battery out was a major task. The instructional video doesn’t show that there are brackets holding down the old battery which are very hard to manage and don’t perfectly fit the slightly shorter replacement battery. All making for a pretty dangerous shorting / fire hazard potential. But 4 hours later, it’s in and working well.
