Another Battery questio (sorry)

[viva]

I have a domestic and starter battery on the boat and I have a shore powered multi-step charger. I take the batteries home for winter and I charge them about once a month with a cheap, Halfords battery charger. My questions are is this sufficient.? Do I need to buy a more expensive, multi-step charger for winter top up?
Thanks

Do you maintain the battery rested voltage, if it's the same in the Spring as it was when you started before Winter, then your doing okay, that assumes you started at 12.7 - 12.9 volt.

If losing voltage run your charger longer.

I use a small solar panel and just leave it on for the winter. Seems to do OK for me.
The type you would put on your dash in your car, about £10 to £12 off ebay.

If the Halfords one isn't multi-stage you could get a cheap lidl multi-stage battery charger, about £13

And the Lidl one is on offer this coming Thursday.

Only snag with it perhaps is that if the power is disconnected it has to be manually reset. Makes it a little unattractive if you want to set it going and forget it for 6 months.

Cheap so you pays your money and takes your chances.

Ctek undisputed I think when it comes to quality, but of course substantially more expensive

Yes they stay at around 12.75v and 13.1v

Lidl charger, max 3.8A. Probably OK for the intended use at home, but rather low output for on a boat:

As I just said in another thread:

CTEK make a huge range, these ones are excellent:
