Numax XV31MF Heavy Duty Ultra Deep Cycle Leisure Marine Battery - 12V / 105Ah / 740EN / 925MCA - Dual Purpose (Starting & Auxiliary) - 3 Years Warranty

Fitted three of these in my yacht, with a victron charger. They seem to be good quality and are working perfectly after a year. About half the price that I was quoted by my local chandler.

Would recommend to buy so good so far 👍 value for money easy installation

Well packaged fast delivery can’t fault the service or product ⭐️⭐️⭐️⭐️⭐️

When we eventually got the battery after the courier's first lost it then broke it, it was perfect for our 24 foot motor sailor. I have to thank Tayna batteries for the excellent service of sending out 3 batteries to make sure we got what we needed as soon as possible, great and responsive service by customer service team, 10 out of 10 for their efforts.

Great leisure batteries for a good price. All fitted and working brilliantly.

I bought a pair of these batteries for my boat in 2017 ! They have been an absolute lifesaver on more than 1 occasion. They are dual purpose so they can be used to power all the pumps and lights and refrigerators without worry, and then still give enough power to start a large outboard engine in the morning!! I’m writing this review in Oct 2025 so they’ve outlived their 3 year guarantee by some margin! Highly recommended and will buy another pair when the original’s finally die👍🏻☑️

Arrived very quickly and very easy to fit just remember to remove the delivery lug

Caravan battery failed to charge after 8 years heavy use.tight recess to get in and out so ordered same battery again and it was identical in size and both connectors so easy swap
