    Hi,
    I've got a Chausson Flash 14 which comes with a single Numax 95ah battery. So I though I would pep it up a bit and get another.
    Went to my local battery supplier who are a big firm supplying batteries nationally, who told me that the Numax 95ah had changed to 100ah. I said that I needed 95 ah as I had heard that the batteries must be exactly matched or they will not work optimally when wired in parallel. The guy at the shop suggested this wasn't a problem.
    I have seen a lucas 95ah battery on ebay (which is a bit cheaper)
    So was he right? And which one should I go for? Same make and slightly diff ah or diff make and same ah?
    Thanks

    Ideally they should be identical in size, make and age to get best results

    Hi
    If you have two different size batteries they will only charge to the lower rated one, I have two odd ones on my 76 and working fine, I did this because I allready had a spare one,If you can get the same that would be better as you will be buying new. pete :thumb:

    Ah, so the guy in the shop was wrong then!

    Looks like I am better going for the 95ah one I've seen on ebay. Shame it isn't the same make but I can't find anywhere that sells a Numax 95ah one as it looks like it is discontinued.

    Thanks for replies so far, any other opinions welcomed.

    Before I knew better I had a problem on a previous m/h when a dealer added a second leisure battery for me but different to the existing one. After this I could not get a full charge in the batteries. Eventually I chucked both batteries out and replaced with two identical which cured my problem.:BigGrin:

    What age is your existing battery?

    At that age it's probably at least half way through it's useful life.......I would opt for a pair of new ones for long term efficiency. Otherwise your old battery will drag down the new one fairly quickly.

    Go on....you know it makes sense!

    Ok folks, so it looks like my googling skills are pretty lousy!

    Now to decide whether to go for one 95ah numax or 2 new ones!

    Thanks for comments and links :Smile::BigGrin:

    A short while ago the people in charge of battery standards (cant remember the proper name) moved the goalposts a bit.

    they reclassified the true ah rates and you may find a new 100ah battery is exactly the same as the old 95ah.

    cant remember the way it worked but it was something along those lines.

    Cheers for the link techno100, they look like what I might be after.

    And thanks aba for the idea on forklift batteries. But if I go for those are they the unsealed type meaning that they have to be vented to outside? This could be a problem as my batteries are under a seat inside the van.

    Thanks
