Battery chargers

I recently debated between an M200 and a Victron Blue Power, both 15 amps.
Chose the Victron because;
I didn't really want a charger that could pulse at over 15 volts, I'm unimpressed by these claimed desulphation modes.
It was a bit cheaper.
I quite liked the idea of the 13.2 volt storage mode for long term connection.
So far I'm pleased.
 
I'd agree with Tallulah but it depends upon how quickly you want to recharge the battery ... and from how deeply discharged you want to recharge.

The M300 ( 25 amp max) might be a better choice although these are max output currents and in practice the battery may not accept such high charge rates, esp if only lightly discharged.

Probabaly the M200 will be more than adequate most of the time but if you ever find yourself with deeply discharged batteries and needing to recharge as quickly as possible you'll curse not having bought the larger model.

Had a Sterling 30 amp jobbie that I transferred from one boat to another over a 7 year period. Gave excellent fault free service including leaving the batteries on charge all winter. Will be buying another to replace the cr*p Yanky/ Chinese one fitted to my boat by Bowman
 
I've got the Ctek M300 servicing 255ah bank, been running for 2 years with no problems. Batterys are always spot on with no excessive gassing or water loss.

Very pleased with it, bought it when it came packaged with a small charger which I have also found useful for occasional use on engine start battery.
 
I have the M100 powering a single 110ah battery and the charge time is fine there even with the low power. My model is also IP65 rated (as opposed to the IP44 of the higher models) so is a little more flexible with mounting positions. Not that it helps you, but thought I'd mention the IP rating anyway as something else to consider.
 
I have an M300 charging 2 x 120AH domestic bank. It is available as a package with the tiny MX 'Starter' (a badged CTEK MXS5.0) which just maintains a seperate engine starter battery. I keep this permanently connected. This way the starter battery (which is effectively always fully charged) isn't subjected to the charging regime of the domestic bank. I can always bus connect the engine starter batt. to the main charger is it were ever discharged for any reason...

I decided that the higher current provision (of the M300 over M200) was a good idea.
 
I have the c-tek m200 on the domestics and the little msx 0.8?? on the starter and the m200 keeps the domestics fully chgarged and I live aboard. Never had a problkem with overcharging or gassing either, plus I liked the fact they come with the wiring already connected to the chargers.

If you are in a marina, and have access to permanent shore power, it's probably OK. I use a generator to power my charger, so need it to charge quickly..... I therefore have a 70A charging facility, and wouldn't consider less than 50A.
 
Sharp and Enright in Dover (chandlers to the Nobility) have got the Ctek 300 with the mini charger for £240. (worth a haggle?).

Give them a ring if you're interested, they will post.

Usual caveats.

A big +1. these piddling 15A chargers are OK if on permanent shore power and can afford to wait a week for the batteries to recharge. I have a 65 amp jobbie (Sterling) which does it for me and my batteries - metered at just over 70A output when on full load.
