I have two batteries on my Channel 31, engine and domestic, what charger should I get and how do I calculate what amp output to choose /forums/images/graemlins/confused.gif

What size batteries are they? Also, are you normally in a berth where you are plugged into the mains?

Go to Halfords and get one of their deep cycle leisure battery chargers. Will work for any yacht battery and has a maintenance cycle to stop overloads. Costs much less than the equivalent from a chandler. MUST be for deep cycle leisure batteries or will cause damage.

John,
They are both 80amh and we are usually berthed with shore power.

Then get a Sterling/Adverc/Driftgate2000 or similar power supply unit that will both charge your batteries together or isolated, and supply 12vdc when on shore power.
I've got 3 x 110Ah batteries for general, and 1 x 100Ah for starting. All are charged by the Stirling battery charger, that also gives us 12v when alongside on shore power.
As an instance and for more information on Sterling, see http://www.force4.co.uk/acatalog/Online_Catalogue_Invertors___Battery_Chargers_20.html
12V 20 amp Sterling Battery Charger Ref: 130007
State of the Art, high quality switch mode Battery Charger. Features: 4 step battery charging programmable for all battery types and battery sizes • Automatic 110/230v crossover • 3 isolated outputs • RFI filter for minimum radio interference • Twin fan cooling for maximum performance in high temperatures • Handles boats DC power demand during and after charging • Size: 300x170x60mm (20amp model: 220x120x45mm)
or for Drifgate2000

The X-CALIBRE is 3 Stage Battery Charger employing switched mode technology to provide an efficient charger that will recharge batteries both quickly and safely. Using the IUU three stage charging routine it provides a bulk charge delivering a closely controlled current to the battery during which phase about 75% of capacity is restored. The equalisation phase reduces the current to maintain the battery at the 'boost' voltage. This phase brings the battery to about 98% without excessive gassing. The final stage 'float' allows the battery voltage to drop to the float voltage. During this phase the current output from the charger is automatically adjusted for any change in load.
Admittedly, none are that cheap.
