Hello All
Back from the weekend on Capriola when I was able to check the batteries
The Boat has been connected to the land line for two weeks and all seamed fine on Friday night and connected the TV aerial up and settled in for the night
Saturday was the day to check the batteries so with the land line connected the invertor was reading 13.5V.
Multimeter reading across 1 to 6 Batteries was 13.75V
Multimeter reading across Starter Battery was 13.63
I then disconnected each battery in turn and recorded the Voltage as follows
Battery 1 13.62V
Battery 2 13.63V
Battery 3 13.63V
Battery 4 13.63V
Battery 5 13.62V
Battery 6 13.62V
I reconnected the batteries and waited 2 hours and took another reading
Batteries 1-6 reading was 12.84V
with the batteries connected up and no land line hooked up we continued to carry out our daily life
the 12v Radio was used for about 5 hours 12V fridge, 240V digital clock 240V MiFi and 240V phone charger
I cleaned and tested the bilge pump three times in a bucket Used the macerator pump three times used the water pump for the kettle and washing and cooking watched 240V TV for 4 hours had 6 LED lights on for about 5 hours and the battery reading was 12.7 when we went to bed
At 4 in the morning we were woken with the beeping of the invertor showing a fault
Have the batteries had it or am I expecting too much from the batteries
Any advice gratefully received
Roger
