I have a lovely set of new LA batteries sat in my house. Brought them a couple of weeks ago. Was intending them to be fitted by now, have put this plan on hold for a while due to various reasons, basically not sure when we will be heading out of the marina. Any advice from those that know about such things as what’s the best for these idle batteries? Don’t want to fit them and just leave them in the cold for weeks. There warm where they are but would it be a good idea to hook them up for the odd hour to a standard charger to keep them happy?

Yes, always charge new batteries - who knows how long they've sat about. I bought one for my non functioning bow thruster 2 1/2 years ago and it has remained fully charged since, I check it every six months or so. Sitting around partly discharged is bad.

A cheap battery charger I had for years recently died so I bought another by the same manufacturer. Nice and cheap, maintains a float charge, haven't had the occasion to try the emergency start idea. Surprisingly heavy. www.tayna.co.uk/battery-chargers/car/sga7a17/Make a insulated box for your new batts. Cold temperatures are bad for batteries but so is too much heat.

If you were sure they were fully charged when you got them, I’d say do nothing. But since you don’t know when they were last charged, I’d be wanting to hook em up to a charger. Once you have charged them fully, they don’t need to be charged again for a month or two.

Thanks all . I did check the voltages on delivery, all between 12.77 and 12.82 but I think il pop em on charge for a bit anyway. Will dig charger out of garage and see what it does.

I've sometimes wondered about this. The consensus seems to be that unless you fully charge your batteries every couple of days that they sulphate and lose capacity. So, when you buy a brand new battery, unless it rolled off the production line within the past 48 hours it's already on its way towards being knackered.

Dont leave them on a concrete floor for some reason it seems to knacker them up, we carried out a little experiment at the garage put two new batteries one on the floor the other on a plank monitered the voltage and the one on the floor lost voltage quicker than the one on the plank! In the boat my batteries were always off the swim as the same would happen

Well I’ve charged them, only with a standard smart charger thingy at home. They only took about half an hour each before the charger said full. I want to fit em and go boating but can’t for now.. life is full of surprises huh.

What's the difference with boating? You can still isolate yourselves. Life's better by water. I'll certainly still be having a few days on the boat over the next few weeks.

It's ok to go boating as long as you exercise self isolation rules. No sharing locks and no idle nattering with other humans.
Strictly no kissing and observe social distancing protocols then all will be okay.
It's a bad one but if you are sensible you can avoid a horrible slow breathless death from pneumonia symptoms.
Another thing is to strictly avoid letting people cough directly into your eyes or ears.

The virus isn’t the thing stopping us from boating right now, it’s another issue. Temporary I hope. All being well we should push off ibefore the end of March.

In the boat my batteries were always off the swim as the same would happen Was that one of the wooden cased glass batteries or one of the rubber/steel cases? Because concrete used to damage them.. Modern batteries are impervious to this. northeastbattery.com/do-cement-floors-ruin-car-batteries/

Modern batteries are impervious to this. northeastbattery.com/do-cement-floors-ruin-car-batteries/Just normal car batteries, we put it down the the floor being colder than the plank of wood, PB batteries gave me half inch thick corrugated plastic sheets to use with their batteries to keep them off the stern and thinner ones to put between the batteries, I used them but didnt inquire why?
