    Hi guys, it seems we need a new leisure battery in prep for the Peterbourgh show. I've looked on here and read about batteries etc but it's still well over my head and I haven't got a clue! I've seen some on Amazon one stands out due to its reviews Numax leisure battery 12v, 100ah, 1000CCA, it's advertised at £70. Is this a good price or make? Should I stay away from Amazon and buy from a specific retailer and it still confused what this 100ah/ numbers code thing means. Any advice welcome

    Thanks for the link it seems like 'banner' is a popular brand and the bigger 'ah' is better and the link certainly helped cheers

    I was told by someone who is supposed to know about these things that the construction of the battery, irrespective of the manufacturer, should be compatible with the type of on board charger you have fitted to your van.

    I see that would make sense. This is well over my head, more research it is and more checks to our van.

    Cheers

    Hi Ains-camper

    The 100ah is the capacity of the battery, so it should give you 100 amps for one hour or 1 amp for 100 hours, I say should as for a start you should not discharge lower than 50% which would be about 12.2 volts with no load on the battery, so straight away your 100ah battery is only really 50ah useable.

    The other figure of 1000cca is saying it will give 1000 amps for a very short burst to start an engine, engine batteries tend to have lots of thinner plates to give this burst of power where what we want is less but thicker and heavier plates to give a reliable steady drain of power.

    For a starting point I would look for the heaviest battery at a given capacity as this is a pretty good indication of its quality. As The Tincas says you need to make sure that your new battery and your charging system are compatible so if you are looking at a battery that says its Gel or AGM or flooded lead acid, make sure that your chargers both mains and solar have a setting for the battery type of favour.

    Then comes price I am sure you can get a 100ah battery for £70 or you could pay closer to £200 so you have to make your own decision as to whether the more expensive batteries are a benefit to you.

    Of course the most important thing is make sure that whatever battery you buy it will fit in the available space in your van.

    Do a search for 'Banner batteries' they are popular but opinion is divided as to whether they're good...

    My preference is Varta, have previously bought from Tanya and Battery megastore, both being good to deal with.

    On the high street, gooutdoors are usually competitive on standard leisure batteries (y)

    Whatever you decide, before you buy check the dimensions of the battery against the maximum size you can fit into its location. You don't want to buy a battery and then find it's too big :)

    my vote would be for trojans but do check the dimensions as they are not standard sizes and they weigh a lot

    Wow thanks guys a massive help. I didn't even know about of think about how it's charged. We've only had the van a month so it's all completely new and a mine field. Our current battery only lasts around 15mins and it had been charged via mains whilst parked up on site and I assume driving also charges it?? hence why I'm thinking its pooped and we need a new one. Next on the agenda is to find where it is, size it and find out which charging system is used. A real big help thank you!

    Check the fluid levels in each cell and if necessary top up with distilled water. Then try battery again before you splash out.

    Having read all this I am going back to photonic universe for two of their gel batteries as my batteries are beneath the drivers seat. Had originally gone for two 90 amp gel batteries with Dethleffs but they fitted AGM batteries which died within weeks although we did not realise as at the time we where mainly on hook up. It transpires that the Shaudt EBL101 that is under the passenger seat does not support AGM batteries only Gel or Acid. Very disappointed with Dethleffs for this schoolboy error Orr skimping on battery cost!

    Most of the Hymer group have been fitting AGM's for a few years and only been fitting a suitable charger for a few months. Just replaced my AGM's with Gel's.

    If youre buying a different battery check the size first so it will fit in the space available. Tayna shows dimensions on their site.

    Be aware that not all MH's alternators charge the leisure battery whilst driving - our 2010 Autoquest 145's doesn't - soon to be rectified :)
