I have 3 x 120ah Batteries probably 12 - 18 mths old , how do I test them too make sure they are all working evenly and that 1 isn't labouring.
Just recently purchased this Motorhome and it has the Drifter Pro Battery monitor showing me the status of the Batteries. Does this system read all 3 Batteries or only one battery.
Thanks
Mick

The monitor would be on all 3 as a group and you would need to check each battery disconnected with a battery load tester.

Thanks Totalrv , I thought that. I might get them checked out by a autoelec , because I think something is wrong , either the Batteries or the Monitor . Thanks again . I noticed you are at Tweed Heads whereabouts , you could pm me if you like.
A battery load tester only tests cranking capacity and is not relevant to cycling batteries. After fully charging, disconnect them all and place a known wattage load (like 50W a headlight globe) on each and record the time and voltage every half hour over at least 10 hours or until the voltage gets to 10.5V.
Cheers, Peter

A battery load tester will not test the battery capacity but it will show up an ailing battery.

Peter are you seriously telling people to drag their batteries to 10.5v for a damn test..... you going to replace them....????
10.5v is dead flat and you might as well just disconnect them and send them to the recyclers..

Sorry, but the standard tests for battery capacity take them down to 10.5V and doing so will not do them any damage.
Check if you wish.
Doing so on a regular basis will certainly shorten their life. A big difference.
Cheers,

You make valuable contributions to this blog site and people appreciate your participation. When contributors post advice you disagree with there are nice ways to correct them and not so nice ways. Don't diminish peoples respect for you by making blunt and offensive posts.
