I would like to improve my understanding of what is going on with my leisure batteries and Sargent system and would appreciate input from informed members.
I have been undertaking a load test on my leisure batteries, 2 x 110 AH. They have been fully charged and left to settle with no incoming source. Voltmeter reading at start of test 12.7
I then put a load of 6 Amps on the batteries and after 1 hour measured again with VM, reading 12.52 V. The Sargent Control panel stated 11.9 V. good.
The reading was the same for the next 2 hourly visits. i.e. 6 Amp draw and VM reading 12.5. (did not check control panel).
On 4th visit (4 hrs on load test) one of my TV's had shut down due to a low voltage warning and my control panel was stating 9.8 V poor. Yet when I measured with my VM directly from the battery terminal I was getting 12.5 V.
I have shut down the system completely now and will see how far the batteries recover tomorrow morning.
Can anyone make sense of this ! I know both the sargent system and my VM are not faulty but clearly there is a conflict.
It's possible my batteries are on there way out, 4 years old and hammered last winter in Morocco but still reading 12.7 when fully charged.
