Above shows battery revitaliser cct.
Elektor had a more complex cct. in the September 2001 issue.
Don't know how successful it would be with sealed gel batteries.
CPC / Farnell have similar prices to ARD with CPC offering free carriage
with orders over ?30 (ex. vat )
I think Farnell have free carriage over ?10.
Again no connection with either company, just use them a lot.
