Hi guys. Have a 2018 Titanium Everest with original battery.
Have used Forscan to enable dual battery mode,and set to 90% charge Max.
When driving, battery goes up to 14.something volts.
After stopped for 30 minutes, resting voltage drops to 12.0v
This around right?
Or should it be higher?
regards
Alan

That is low, it should be around 12.7 if it's full, @ 12 volts that is around 25% and very close to flat.
My guess is the battery is on the way out, or there is another problem.
Are you doing a lot of short trips?
Sealed or Flooded Lead Acid battery
100% = 12.70+
75% = 12.40
50% = 12.20
25% = 12.00
00% = 11.80

what did you end up with my battery is on 95% dual mode and still sits below 12.5 most of the time. might just wind it up to 100% dual mode and see how long it lasts guessing it will degrade it quicker?
time for a new large capacity one now I have more accessories.

To my knowledge auto batteries are rated on Cold Cranking Amps, not amp hrs like a storage battery.
