Nicads? Reliable? Tell more!

These `marine deep cycle batteries' people mention: are these just
normal open-top lead-acids designed to allow deep discharges without
plate sulphation? I'd been thinking in terms of lead-acids as what
I wanted: I don't really need the current capability, but capacity
and reliability are important. If not, what are they? I'd need to
work out what the UK equivalent is.
