Are my leisure batteries dead?

Is it possible that using this method you could get continuity buzzer sounding in reverse across the circuit ? Hence gives a false read ? If that's the case then the fuse needs disconnecting to check it. Or test for voltages at the points arrowed. 2 different voltages would indicate a blown fuse.

No, if the battery cube fuse is blown the multimeter buzzer won't sound but you are correct that you can always check the voltages either side the cube fuse after setting your multimeter to DC Volts, if they are different the fuse has blown

Has anyone any experience of these batteries.
They seem a lot cheaper than the other alternatives and they have a 5 year guarantee.
They are exactly the same dimensions as Varta originals and have a bigger power rating.
Has anyone fitted these ? ......opinions ?
Thanks

Two fitted in a Caddy Conversion four years ago, still going strong, no issues.
They run an inverter that powers a microwave and a Tassimo machine.
