Reading through the different battery threads and this one seems like the place to pose my current conundrum.
2021 with dual batteries and most accessories running off second battery. My camper charges off the starter battery as recommended by Redarc which is what my camper uses for BMS. Use case consists of plenty of punishment, long days towing on and off road with plenty of trail running in between.
Camping this weekend and I get the beeping alert from my Redarc battery volt meter upon start up. Voltage is dipping into the 10 volt range under starting load at camp where temps were in the 30°s. Testing today with my battery load tester and it reads 11.5 under load in my garage.
While not being driven these batteries stay on my NOCO charger. I try to drive once every 10 days, truck is a weekend warrior with a few multi week trips during the year.
I’m on the fence if I need to replace now or not. However, we do have a 2 week trip to big bend and southern New Mexico coming up in December that has me leaning toward replacement.
Another note, there is some evidence of seepage on top of the battery, see picture.
It seems like the Toyota Truestart is the way to go for most cases but wanted to check in here with my specific use and get yalls thoughts.
There is probably some prorated warranty on mine given its 4 years old but I really don’t care to hand my key fob over to a tech just for a battery so I’ll be happy just buying new.
Another question… are the Trustart maintainable batteries? I’ve never pulled the caps and had assumed they did away with those by now but could be mistaken.
