Can anyone recommend a battery charger for a 110 Ah leisure battery please?

Can anyone recommend a battery charger for a 110 Ah leisure battery please?

Depends what you want it to do? Charge it quickly, charge it overnight, or keep it topped up and healthy over the winter, etc. ?

If you don't need to charge it fast, I reckon an Optimate or equivalent is about the best bet. It will charge at a fairly leisurely rate, then drop to a trickle when the battery is full. It will also pulse a load across the battery during long periods of trickle charging to prevent the battery getting sulphated.

The only box it won't tick is rapid charging. They can be had for about 40 quid IIRC, although there are cheaper clones that may or may not be as good.

If you need to fast charge on a regular basis I would go for a switched-mode regulated charger designed for caravan use that will deliver 20 or 30 amps but, importantly, with the voltage accurately controlled. Fast chargers / boosters for car use are really only suitable for emergency use as they can overcharge the battery.

The only thing I would say about the Optimate is that it is only recommended for batteries up to 50Ah IIRC.

In practice I don't believe that this will be a problem except if you connect a completely flat 110 Ah battery across it, it may well time out and stop charging before the battery is fully charged.

In this case, you could probably just switch it off and back on and let it have another go. I think it will deliver 1.2 amps for a maximum of 48 hours before it decides the battery is not responding and gives up. Obviously at 110 Ah battery will need two shots of this.

The same manufacturer do make bigger chargers, but not sure if they have all the desulphation modes, etc.

I will never let the battery go flat, I have a Draper Intelligent Charger, rated at a max 60 amps.

I also have a Machine Mart trickle charger 0.5 amp max.

I just want to be able to keep it topped up over the winter months.

You want a trickle charge like the optimate.  However if you are spending the money I would get a 4 stage which will handle battery charging under all conditions.  They are more pricey but worth it.

Is the battery AGM?  If so it will lose charge much slower thn other types of battery.

I have a Ctek car charger can leave connect for long periods.

They do a marine version for batteries upto 120ah
that might work?
