Miata Battery 8AMU1R
December 25, 2021
by on December 25, 2021

I just put this in the car (2002 Miata) today, and was able to start the car. Can't say much about the long term usage yet. Very quick delivery, I got it a few days earlier than I expected. The price was about the same as everywhere else. The reason I gave it two stars is because it's a vented battery (just like the stock battery), but the vents on the battery are round tubes - the stock battery uses rectangular vent tubes. The rectangular tube fittings do not fit on this battery. I ended up putting little pieces of vacuum tubing on the round battery vent tubes so the rectangular tubes fit. Also, the battery has some kind of funky castings on top of it so that the battery hold down bracket does not fit well. I'll have to remember to check the battery regularly to make sure it is still fastened down and that the vent tubes are still connected. It just occurred to me that I will probably try to grind the castings off of the top of the battery so that the hold down bracket fits better.

The battery was well packed with cushions and arrived sooner than expected.

It’s been only 3 weeks but the engine starts fine in the cold morning.

First one lasted 7+ years sitting outside the entire time. May not even be dead now as the problem turned out to be the fuel pump. Wish it wasn't 50% more than the first time I bought one but what can you do?
