Determining AH rating of aging batteries
My Trojan 125's are almost 5 years old now, when they were new they were rated at 240 Ah. Now my trimetric is showing 70% at 12.1 volts which I know is wrong. So how can I determine the true Ah rati...

On another note, it is possible that if you seldom use the RV that over a period of time, getting a false % SOC reading on your metering...This 'may' happen after a prolonged period of inactivity (RV non-use) where a small amount parasitical losses (say, rv circuit boards) overtime occur...Over a period of time, these slight losses can produce an unwanted (stray) accumulation of magnetic flux lines across the metering shunt (inserted into batt Neg Cable) thus a resulting phantom SOC% reading. The remedy for Xantrex LinkLite metering (not sure about Trimetric...) is to do a manual synchronization (basically a reset - a return to 100% SOC) after confirming battery is fully charged.
