I see your point, but I was thinking of the last time I used a

a 12V SLA will never give the performance and deep discharge capability
of a NiCd or NiMh pack though.

They're capable of several hundred amps to start a car - so I'd say the
performance will be ok. But of course you shouldn't deep discharge them.
