Battery Low Voltage

[dski]

2022 5.7 hemi with etorque

Found several threads with others with similar issues but they never seemed to post a follow up solution. I see Ram tend to have a lot of bad batteries after 2-3 years. Over the course of a few months my 12v battery slowly loses voltage until it gets around 11.8V. It will have a freak out then where warnings come on the screen and all sorts of errors and thing shut down like parking sensors and collision avoidance..... Sometimes when it hits this state etorque seems to stop charging the battery. If I put a charger on the 12V and recharge everything comes back and works for a few months. Etorque while driving seems to send a consistent 13+ to14V to the battery. I used one of those Amazon battery testers and its say ~94% CCA health good battery but often says just low charge.

Don't want to bother with the dealership for just a bad battery. Thinking this is very likely just a battery starting to fail?

Upgrade to an H8 battery while your at it.

The battery on my 2020 ran down when it was around two years old, got a jump and took it to the dealer. Charging system and battery both checked out OK, tech suggested I keep it on a "battery conditioner" given that I may not drive it for 2-3 weeks at a time.
.
I bought a NoCo Genius 10 and keep it hooked the 12V battery when I'm not using the truck every couple of days, it's worked fine since then, no issues.
.
The stock battery does seem like it's not a particularly strong battery, but thankfully for me the Noco Genius 10 conditioner makes up for that. I think for me it was a combination of an inherently sub-par factory battery, not running the truck for a couple of weeks at that time, and it probably was doing one or more OTAs in that time...kind of a perfect storm that brought the battery down
.
I also always carry a Noco Boost GB70 with me at all times now, no matter which vehicle I'm driving.
