Hi Guys,
Please share: What voltage you get when idling and being driven.
I have a 2010 RCZ 200THP. My battery was up for replacement and I thought i would give a Lithium [LiFePO4] battery a try. I purchased a Lithiumax battery which is meant to have more CCA and AH than the standard lead acid battery. http://www.lithiumax.com.au/_p/prd1/407 ... ry---bonus!
I had problems where the battery doesn't seem to be charging after driving. I replaced the battery and it still seems to be having issues. The seller of the battery thinks i might have a problem with my car electrics and suggested i take it to an Auto Electrician to diagnose.
I wanted to get an understand what the normal voltage you guys see when your car is idling and when it's being driven.
Mine is currently reading 12.7 Volts while idling and 13.1 volts while driving.
Both of these figures seem a little low to me from what i can gather, i've read they should both be around 14V on standard older cars.
Does our ECU control regulate how much voltage the alternator creates? I read that our car can reduce the voltage to increase fuel efficiency, but this is causing a problem for me.
Otherwise it may seem that a LiFePo4 battery may not be suitable with our cars as the voltage required for 100% SOC is 13.3v vs 12.7V of lead acid.
Here is the stage of charge indicator for the LiFePo4 battery which i got from my supplier:
Fully charged resting state is 13.3-13.4V
13V ok.
Below 12.7V approx 50%.
10V approx 90% discharged.
Here is a lead acid state of charge:
Thanks in advance!
