Anyone tried fitting an Optima Yellow Top 5.5 into the standard battery bay of a Disco 1 (1998). I have measured the bay and reck it should just about squeeze in but its a bit of an expensive mistake if it wont quite go (I'll be ordering it on-line!).

I'm aware that the clamp will probably need modifying due to the extra height but hope to not have to replace the HT leads etc. as I;m a little short on time at the moment.

Ta.

PS - do I understand from other threads that the Rev Counter is fed from an electrical output off the altinator. I had a squeek from the belt (especially in the rain) for a month or 2 but last night the squeek disapeared completely but so did my Rev counter, it now wobbles violently around 500 - 1500 revs if im hammering it at ~70mph (usually 2.5-3k) but anything less and it sits flat 0. Rev counter is not an urgent problem but if it is 'coz the belts about to drop off (conected to the squeek?) I probably need to deal with it a bit more urgently!

Are you planning to use a Yellow Top as your main car battery then?
 
Yes, I'm planning to use it as my main bat. I can't justify 2 bats at the moment hence wanting to use the "really big" yellowtop which does claim to be a duel purpose bat (starter and deep cycle). The plan is that this bat will survive long enough to become my aux. bat on a 2 bat system (probably on the next vehicle :().
 
Think I may well chance ordering it tonight, you'll know how well it fits shortly based on if a v. new 2nd hand YT appears on here next week!
