What battery fits?

[spanky3]

My numax 896 battery has given up after 7 years so i ordered a new one from Tayna.. same make, same model but it's nearly a centimeter longer.

Anyone know an 896 battery that will fit a caterham? Old one was 180mm x 125mm and car is a 2007 metric and Tayna say all 896 batteries are the same which clearly they're not.

I was trying to avoid Banner as I only ever read bad things about them, but it might be the safest option.

986 sized batteries are commonly used alternatives and what my car already has but it seems they are not all created equal.

Thanks all. I ended up playing it safe, Tayna swapped the battery for a Banner.

My Numax lasted 8 years with Ctek assistance so we'll see how the Banner compares. If I could have measured exact dimensions of various '896' sized batteries I'd have gone with another of those though. (And lesson learnt that battery standards aren't all that standard)
