I put the ES 350's own battery back, also somewhat depleted after
sitting awhile. It's a slightly smaller 3.2AH version. After sitting
overnight, I was able to get it the UPS to stay in ON mode if I
unplugged the UPS from power, then plugged it back in. I roughly
measured nearly 100mA of charge. I tried swapping the other battery, and
it was back to 5mA. I'm considering that battery toast.

Yep, it's dead.

The battery in the one UPS that lasted only 5 minutes has been drained
once or twice before, so has lost capacity from that. I'll get a pair of
batteries to replace both of the ES 725's I have, as both are nearly the
same age.

Also dead.

Favorite UPS battery vendor of the week:

Now to figure out where to safely recycle these. I have a pair of old
12AH's from another UPS that have been sitting around in addition to the
ones I'll be replacing.

See "drop off locations" on the right side of the page.
Not every location will take SLA batteries, so it's best to ask before
leaving a pile on their doorstep. In general, any place that sells
SLA batteries, will also take them for recycling. Also, nobody wants
a leaking battery so make sure it's not dripping acid.
