I was looking for some Sealed Lead Acid battery dimensions and found 
the yuasabatteries.com site.
A more useless site for practical applications would be hard to find.

HOWEVER

Their UK site is utterly superb:

        http://www.yuasa-battery.co.uk/index.html

A vast array of intelligently presented information on the wide range 
of Yuasa's excellent lead acid battery products.

All their SLAs plus NiCd, NimH

        http://www.yuasa-battery.co.uk/industrial/products.html

    NP series SLAs

            http://www.yuasa-battery.co.uk/industrial/np.html


Sample chart from a data page
Discharge curve for an NP series battery at 25C (77F) for selected 
discharge rates from 0.05C through 3C.
It's interesting (but not unexpected) to note that while the ratio of 
discharge rates between 0.05C and 3C is 60:1 the ratio of times to 11V 
(on a 12V battery) is about 350:1. ie the battery has only about 20% 
as much capacity when "crash discharged" at 3 times its nominal 
amp-hour rating than when discharged over 20 hours. You even get an 
extra 25% capacity when going from the 10 hour to the 20 hour rate.

Homespun free advice - observe or ignore as you see fit :-):
When specifying lead acid batteries you will seldom go wrong if you 
buy Panasonic or Yuasa (and I have no financial or other interest in 
either company). Other batteries may be cheaper or even much much 
cheaper, and sometimes you may get even better value for money than 
when buying from P or Y - but there's also a large number of very very 
bad LA batteries made, so if buying on price you need to be extremely 
vigilant. In the local market I can buy equivalently rated batteries 
for about 40% of the cost of eg Panasonic's products - and I certainly 
am happy to do so in some cases. But be aware of the differences. When 
buying (especially in NZ) do shop around a little. Prices for the same 
product vary vastly and you can easily but no-name brand junk for 
substantially more than the very best if you insist on doing so. eg 
DSE sell batteries I have never heard of, and which MAY be OK for 
about 50% more than you can pay for Panasonic batteries elsewhere. 
Jaycar are cheaper than DSE and sell both Panasonic and "other brand" 
lead acid batteries.
