some manufacturers see it as a liability. You can
purchase NiMH D cells from Amazon and the things
are rated at a massive 10,000 mah. The 12 vdc SLA
rechargeable battery in a small UPS or alarm
system is only rated at around 7,000 mah. Dang!
Those NiMH batteries have a lot of power.

One time when I was in a repair shop, I noted a
power failure light (like in stores or theatres)
apart in the shop work bench. They had what
looked like a NiCd sub C pack, no longer using
sealed lead acid. Hope they tested those nicads
now and again. You know nicads and reliable.

With the charging equipment I own, I'd need a
set on charge, and set in use. I don't have
the amperage availble for over night charge.

Did the batteries in the emergency lights look like these? o_O
