In Electronics Australia July, 1997 there was an article on an add-on regulator kit for an el-cheapo battery charger to make it fully automatic. Jaycar sell the kit.
I've had trouble finding the article and wonder whether anyone has a pdf file or link that will let me read about the kit and see what requirements it has in terms of the battery charger.
Thanks folks, Dave

** Jaycar, DSE etc kits come with reprints of the original article - if you go to a store the staff will let you examine the kit and instructions.The EA July '97 Add on Regulator etc was shown with an Arlec 4 charger. The article suggests using a transformer with a 13-0-13 volt secondary and a pair of 5 amp diodes for those who wish to roll their own.
BEWARE:
I very strongly suggests you do NOT use a standard toroidal tranny for such a charger as they are COMPLETELY UNSAFE in the application.

I'd be interested to know if it can be used or 24 V batteries
Thanks Phil . . I didn't realsie DSE has it as they are a lot closer for me to visit than Jaycar. I'll have a look there . . and thanks for the advice. I have an Arlec Charger 8.

** The ARLEC Charger 8 is rated at a *meaningless* 8 amps rms OR more correctly at 4.5 amps continuous. The latter figure is the effective charging current.A C122D SCR conducts at about 1.5 volts, so heat dissipation will be 6.5 watts or so.
