If your caravan battery won't charge while you're driving, I'd look at a good-quality leisure battery and, just as importantly, the charging system before spending money on an upgrade.

A new battery alone might not fix it. Many modern vehicles have smart alternators, which can reduce the voltage supplied to a caravan while driving. In that case, a suitable DC-to-DC charger may make a bigger difference than changing battery brands.

## Which battery brand should you consider?

For a UK touring caravan, these are the brands I'd investigate, depending on your setup.

!12V 95Ah 850A(EN) - YBX Active® Freizeit AGM-Batterie

1\. Yuasa L36 AGM

(Best straightforward upgrade)

A reputable AGM battery for regular touring, a motor mover and general caravan use. A sensible choice if you want to keep a conventional lead-acid setup.

!Fogstar Drift 12V 105Ah Heated LiFePO4 Battery - Simply Split Charge

2\. Fogstar Drift 105Ah

A premium lithium option if you regularly camp off-grid and want lower weight, more usable capacity and faster charging. You must first check that your caravan's charger and towing charge circuit support lithium.

!Numax Leisure Battery LV26MF Low Cost Batteries Online

3\. Numax LV26MF

Worth considering if you want a conventional leisure battery without paying a premium for lithium.

## But why isn't your battery charging while driving?

Before buying anything, have these checked\:

- 13-pin towing socket\: the permanent charging feed, earth and relevant fuses. - Car's alternator\: whether it is a smart alternator that needs a compatible charging system. - Caravan wiring or charging unit\: whether the battery receives the correct voltage while towing. - Battery condition\: whether the existing battery has deteriorated and no longer accepts charge.

The Camping and Caravanning Club explains the different charging methods and why appropriate battery-to-battery charging equipment may be needed. www.campingandcaravanningclub.co.ukwww.roadpro.co.uk

## Let me narrow it down to the right upgrade

One important question first: what do you tow your caravan with?

1\. Tow vehicle

Modern car (2015 onwards)

Older car (before 2015)

Van or motorhome

2\. Current leisure battery

Standard lead-acid

AGM

Lithium

Not sure

3\. How do you mainly use the caravan?

Mostly sites with electric hook-up

A mixture of sites and off-grid camping

Frequent off-grid camping

4\. Budget for the battery

Under £100

£100-£200

£200-£400

£400+

With those details, I can recommend the best battery brand for your setup and tell you whether you should fix the charging circuit before replacing the battery.

For a 12V leisure, caravan, boat or camping battery, the best all-round choice is the Attwood PowerGuard Series 24: it is durable, vibration-resistant and includes secure battery restraint, though it is best suited to sheltered installations.

### Best UK options

- Best overall: Attwood PowerGuard Series 24 - robust polypropylene construction and strong buyer feedback; check UK availability and battery dimensions before ordering. - Best budget option: Numax Group 24-31 Battery Box - approximately £29.99, suitable for 75-135Ah batteries, with a five-year warranty. - Best compact option: NOCO Group U1 HM082BK - approximately £17.99, for smaller batteries; dimensions are 213 × 183 × 264 mm. - Best premium/large option: Accubox Deluxe Leisure Battery Box - approximately £69.99, offering a more substantial enclosure for leisure-battery installations. - Best for two batteries: Camco 55370 Double Side-by-Side - designed for dual-battery installations, but verify UK stock and compatibility.

Before buying, measure the battery-including terminals-and check that the box has a securing strap, ventilation where required, cable access and enough clearance. For lead-acid batteries, ventilation is especially important; lithium batteries generally need a box sized for protection and restraint rather than gas venting.
