The Best 110Ah Leisure Batteries (UK 2026)

By the Leisure Cell editorial team · Updated 2026 · How we test & score

110Ah is a common upgrade from the standard 100Ah, giving a bit more headroom for longer trips or heavier power use. Here's what to look for and our top 110Ah picks.

Quick answer

A 110Ah leisure battery suits people who find 100Ah a little tight - longer stints between charges, or a fridge and a few more gadgets. SuperBatt, Numax and Exide all offer popular 110Ah flooded and AGM models. The usable-capacity rule still applies: around 55Ah usable on lead-acid or AGM. If you regularly run short, consider whether a lithium of similar or smaller nominal capacity would give more usable power for the weight.

What to look for

Check the physical size, as 110Ah batteries are larger than 100Ah and may not fit every box. Decide chemistry for your usable-power needs and budget. Look at cycle life and terminals. A heavy-duty or dual-purpose 110Ah suits campervans with a single battery doing both starting and leisure duty. As always, match capacity to real daily draw rather than buying the biggest number.

How we pick

We rate 110Ah batteries on usable capacity, cycle life, fit and value. Every pick is a genuine 110Ah deep-cycle leisure battery.

Frequently asked questions

Is a 110Ah battery better than 100Ah?

It gives a little more capacity - around 10% more - which helps if you find 100Ah slightly tight. But it's also larger and heavier, and 110Ah lead-acid still only gives around 55Ah usable. If you regularly run out, a modest capacity bump may not be the real answer: switching to lithium roughly doubles usable capacity for a given nominal size, which often makes more difference than 10 extra amp-hours of lead-acid.

Will a 110Ah battery fit my caravan battery box?

Not always - a 110Ah battery is physically larger than a 100Ah, and caravan and motorhome battery boxes vary in size. Measure the internal dimensions of your box (length, width and height, including terminal clearance) and check them against the battery's stated dimensions before buying. If space is tight, a lithium battery can give more usable power in a smaller, lighter case.

Bottom line

Our top pick is the SuperBatt LM110 (our score 9.3/10) - A practical leisure battery (deep-cycle, 110Ah) for off-grid and leisure power..
