Won't take a charge!

Using what charger? A lot of "intelligent" chargers are anything but
and if presented with a totally dead battery refuse to charge it (many
APC UPS exhibit this useful behaviour). The cure is to put any old
simple charger on the battery for 30 min's then reconnect the
expensive posh one which will work.

I doubt there is much intelligence about this charger. Probably supplied
by Draper for agricultural use.

It has settings for 12 or 24V and normal or boost. Output fused at 15
Amps.

On normal, the battery quickly rises to 13.6V which decays rapidly once
the charger is disconnected.

I have not tried extended charging on boost.
