Sorry to charge in with another battery query.
I am looking to buy an intelligent battery charger for the batteries on my boat. I would probably leave it plugged in to maintain the batteries. I use a 35 ah., 85ah. and a 110ah. leisure.
I am looking at a CTEK mxs 5ah. Will this be man enough or do I need a 10ah?
Fair winds,

It's Ok if you are using the charger on one battery at a time.

Umm, are they all the same type, and are you leaving that one charger attached to all of them on shore power ? That's a different issue all together.

A 5 amp charger will be fine for the 35 ah battery, not too bad for the 85 ah one but recharging times may be acceptably long for the 110 amp battery although no problem if you really only want to use it for maintenance charging.


I assume you'll not be charging all 3 in parallel
 
I've got one and it charges my 110 amphr house battery though its lead acid car type rather than leisure. Its brilliant - i leave the boat plugged in to shore power and it looks after it. if anything I think the battery cycles better since I've bought it. Was suspecting it was starting to loose voltage. gave it a maintenance charge and it came back good.

That said i have a 90 amp alternator on my engine also so i put back quite quick with a bit of motoring when I'm out. I am not a huge current user otherwise so when in the marina the charger provides the current rather than the battery so there is little to put back anyway.

Don't know your regime so can't be black and white but its been a good buy for me.
 
I will be charging separately. I also intend leaving it connected to shore power, probably, each battery for a week. Would the CTEK MXS5 (5ah.) charge it in a week and maintain it (that is the 110ah. leisure)?

apologies my M100 is 7 amp and you are looking at the non marine 5amp version which is cheaper i think. For what its worth, mine will bring my engine start battery from fairly flat. ie will barely turn the engine over to full charge in less than 12 hours so i can't see the 5 amp version taking a week.

Don't ask how i know!
 
I have one which I use on my 2, 80(something) ah batteries. Itwill certainly pump one at a time up overnight to the 7th stage (ready to use) but I haven't seen the 8th light (maintenance) go on yet, even after a week. Not sure but I'm assuming 7 lights means use it if you need to but it's still at the low end of fully charged.

In a week yes.. Should recharge from a low state in a couple of days.

The instruction manual explains the meanings of the various lights.
