My car is not a daily driving one.
Presently there is not AC, nor alarm system but this modification has been made when the car were not that "extreme".
MTBF 2y without charger-mainainer, 3+(since the last replacement is the same) with.
This mod is not intended for cars exposed to cold winter temps for long times (i.e. parking the car outside at -10C for hours).

Best regards
I am also using the Deka ETX20L now. great little battery, and braille has a nice hold-down bracket that can be used to relocate to the trunk.

I'm using a 480 CCA version of this LiFePO4 battery from Bioenno Power (~4.4 lbs) mounted in my trunk. It works perfectly above 45-ishF but struggles below that temp. Honestly, I think they may have mixed up "CA" with "CCA". I swap it for a cheap lead-acid battery in the winter and bring the LiFePO4 in the house (never charge a lithium battery below 32F).

If you go with them, I'd recommend one of their 625 CCA or greater batteries. I think Mr. Pockets has their 1250 CCA battery and loves it.

I have a 15# Braile with mounting bracket I'll let go for cheap if anyone is interested (see it in my build thread). It struggles with a series 2 starter but is fine with series 1.
