Make of battery charger

I can not find an old article (in WW mag) about 5-6 months ago where a type and make of battery charger was recomended for keeping all batteries charged at correct level. It included automatic cut-off and would then re-charge as batteries depleted. It is used when hooked up to a shoreline. To be a bit clearer, my need is to keep the batteries in good condition over winter when the boat is not used very much,hope you can help.

In the August issue, our 'Boating on a budget' feature briefly touched on battery chargers, and mentioned the C-Tek range. Is this the one you're thinking of?

I don't recall the article you mention but virtually any 3- or 4-stage marine battery charger should do the job. For your purpose, a 20 or 30 amp model would keep them at around 13.4-volts and ensure that they are raring to go in the spring.
The charger should be permanently installed and fitted with the appropriate master switch and circuit breakers. A galvanic isolator is also a good investment if you do not have 230-volts on the boat already. If you do not feel competent to fit these, you should employ a professional.
