I've resurrected NiCADS and used it to charge LIPOs (you need to wire ina abalancing connector if doing this). I mostly use it for two 12V SLA gel traction batteries that I use for astro + my loco, discharging down to about 10.5V at worst, and it keeps them tip-top.

So, bought a new one over the internet. It arrived this morning very well packaged (apparently), but when I dug down through the packaging, I found the battery in a sealed plastic bag dripping with acid! Further investigation showed that something heavy had been loaded on top of it, which cracked the top/ post areas and probably been upside down as well to cause it to leak. Waiting for replies from transporter and supplier.
