While having the van serviced on Saturday the engineer mentioned that my less than year old banner leisure battery has had it somehow and needs replacing,seeing as I can't find the receipt and have no proof of purchase I need a battery just to operate motor mover I've Been told a cranking marine type battery is my best choice but I know there's a lot of knowledgeable people on this site so I thought I'd ask on here first for your advice and maybe pointed in the right direction
Thanks in advance dean
Hi, Are you certain the battery is goosed? It might be a ploy to get you to buy another leisure battery from the service centre.If it has lasted less than a year it sounds a bit odd to me.I would check it first before buying another,they are not cheap!

I would have thought that a motor mover would need a cranking battery not a leisure battery as a leisure battery is meant to discharge slowly and a motor mover would discharge it very quickly like a starter motor.
All sort of opinions on batteries. A car battery is fast discharge & fast charge, leisure battery is for slow discharge & slow charge & marine battery is supposed to be both combined but a marine battery will be fast charged by engine alternator, but it won't in your caravan.
In my experience a car battery used as a leisure battery won't last more than a year or so, so I'd just go for a good make 110a/hr leisure battery. You need to ensure battery is trickle charged overnight once a month if caravan is not being used or it will have shortened life
If you are mainly on EHU and only want it for the mover then an 85Ah leisure battery would be OK.If you intend going off EHU then a larger battery would be better.

Motor Mover Batteries : We recommend the following Deep Cycle Numax CXV sealed batteries. The Numax CXV series are the best on the market for Deep Cycle Caravan Motor Mover application.
The Numax CXV range provides durability, starting power and leisure all in one - i.e. they provide deep cycle use for all leisure or marine applications. They also provide high cranking power and are endorsed by motor mover specialists. Benefits also included are the dedicated crimp connectors for the Motor Mover cables, it leaves space for storing the loose cable returns and will not leave you short of power to drive your Motor Mover equipment.
If a Banner battery has failed in less than a year then you were either very unfortunate in getting a poor one or something or someone has really abused it, as they are excellent batteries.
If you only ever want it to power a mover, so it is not used off EHU and there are no alarms etc draining it, then a starter battery will be your cheapest but not necessarily best option. It would depend on how promptly after using the mover you recharged it.
If you could ascertain what caused the Banner to fail and cure that cause, then one of the best batteries for the money will be a Banner Energy Bull.
If you are really in need of a very cheap replacement your local scrap yard should have some batteries for sale, usually less that £20 for a good one. They are out of cars but if you use EHU all the time it is a cheap option that will serve in the short term
------------- We camped for years. In 2019 we bought an Elddis Avante 454. We like it as it is short (6.9m) and fits in our driveway and has a fixed bed.
We had 127 nights away in the caravan in 2023.
thanks for your replies I appreciate the responces
the bannaer battery was purchased in april lst year and has been used 4 times since then to only move the caravan off the drive so I must be unfortunate cause it hasn't been abused.
I would have thought it would have charged off the van charger?as I have the van electric on for aprox 3-4 days per week (maybe im wrong on that point and that's where im going wrong)
ive found proof of purchase through paypal and have emailed them so ill see what happens
the person who wrote the battery off is an authorised caravan engineer who I hve ued for over a decade so its not in his benefit for me to purchase a new one
I would measure the battery voltage, at the battery itself, whilst you are EHU. I say this because I believe it is important to prove the inbuilt charger is functioning correctly.
Depending on the sophistication level of the charger fitted to your van, the voltage should if the charger is operating correctly, fall between 13.8 and 14.4 volts ( latter figure indicates a "smart" charger is employed). If it is below 13.8 volts, pull out EHU and run the lights for 10 minutes, reconnect EHU and remeasure. If it is still below 13.8 volts (or very close) then it is strongly indicating the charger is faulty.
im a mobility engineer,we often get newish batts that fail a test,best thing to do is connect a 12 volt ispection lamp or old car spot lights ect and leave it till its dead,no light,then recharge for 24 hours,dont always work but we have saved many batteries this way.eg,fail at 45% then after pass at 100%.worth a try

Totally agree with above post as it is probably the Nordelettronica charger fault as these were known to fail around the year your caravan was manufactured.You can get them repaired by Apuljack .Here is the link http://www.apuljackengineering.co.uk/chargers.htm
