Any good deals on 110AH 'leisure' batteries just now?

According to the specs, they're about 15% lighter than the XL31 which PaulRainbow recommended in post 2. On the other hand, they're cheaper!

That's interesting as otherwise the only difference appears to be the terminals
I just put one on the bathroom scales and it was a shade over 4 Stone = 25.4kg

Bearing in mind the other recent battery thread, i have to smile here. The two Hankook batteries are exactly the same size, CCA and ah. The XL31s weighs less but is sold as "deep cycle". Wonder how that works, perhaps some more of that special Numax lightweight lead

Well, in the end I bought 2 x Numax 120Ah because they claim 500 cycles.

Numax CXV35MF Sealed Leisure Battery 12V 120Ah 1100MCA 500 Cycles XV35MF

Rather more than I had planned on spending, but an extra 20Ah in the bank anyway.

Thanks all for your help and advice.

Looking at the weight and equivalent Numax versions I do wonder how the XL31s can possibly have the claimed 130Ah capacity.
Both the XL31s and the XL31 are described as ''heavy duty deep cycle'' in the descriptions by Battery Mega store

There is a few on ebay around that price.

I see the Yuasa is NCC Cat-C, whereas most of the others are Cat B, supposedly more robust for regular cycle use.

Am looking at this XDC31MF Numax Leisure Battery 12V 105Ah

It is only 105Ah, but is Cat-A

Would I miss the extra 10Ah ? (between the two )

My previous were Numax from the local farm shop, they used them for leccy fences, nowt so tight or canny as a farmer!

The deep cycle claim in 100% pure nonsense. I have previously emailed them and told them so, but no response. Nonetheless, i've found them to be reliable batteries and think they are good value.

I wish I had noticed the xl31 was heavier than the xl31s. The extra money for the extra Lead would have been worth it.
However the xl31s batteries are a heavy enough lift and are on the boat now. They were easy to fit as the terminals are very accessible and well placed .
The now removed pair of xv110 batteries were lower height and slightly longer.... and lighter . The removed batteries show green on the "magic eye" but were not performing well at all.

I recently bought a pair of Hankook XL31 MF's. The sticker on the batteries that came makes no mention of the advertised 130 AH rating, but rather includes a Reserve Capacity Rating of 120 minutes. Apparently, after a bit of digging, RC is an America rating alternative based on "the number of minutes a fully charged battery at 80°F will discharge 25 amps until the battery drops below 10.5 volts."

There's a couple of formulas which pertain to convert RC into AHs. Including this one, they suggest that the AH capacity of this battery is only 50AH. I assume this AH rating is based on usable capacity though so is more like the 100AH rating you'd usually see.

I can only assume the 130AH rating on the website (Battery Megastore) is based on a C100 rating (discharge over 100 hours) rather than the more usual C20 (discharge over 20 hours). I think this would mean the 130AH battery is actually closer to 95AH, based on looking at another battery that includes stats for both C20 and C100 ratings - of course that battery could have different performance.

Battery Megastore is clearly using different C ratings for AHs across their site without being clear about it. Unfair really. I'm a bit wiser about buying batteries now, but I hope they last well. 200AH or 190AH should be fine for my leisure bank - I did think I was getting 260AH though!

There's a similar 'starter battery', the Hankook MF31-1000, that from the photo on the Battery Megastore site, appears to have a Amp Hour rating of 115AH, but a RC rating of 190 minutes (79.16AH according to the conversion formula) - that appears to be the better capacity battery by nearly 60%. I wish I had bought that one. I wonder if they would exchange them?

Anyone have any comparative experience from using both batteries? Worth trying to exchange them?

What are the physical differences (volume and weight) between the two batteries?

What are the physical differences (volume and weight) between the two batteries?

The XL31MF (the pair I bought) is 28.4kg and L330 x W172 x H242mm; the MF31-1000 is 24.8kg and also L330 x W172 x H242mm . Both Sealed Calcium.

I guess its the heavier the better, despite the stats/ratings?

The XL31s batteries had a little trial at the weekend. A 24 hr stop away from shore power
Nothing too challenging but the voltage held up well.

Further exercise to follow at the weekend and next week .
New batteries are said to improve after a few cycles ....... possibly another old wives tale.
