Recently I tested two 12v SLA s which had been in use
sequentially for some years usually recharged before going
going flat, or at least within one day.
Both were run down to 10.5 v with a 10 ohm load and then recharged to 14v,

The Yuasa 7 AH bought 2005 was good for about 2.5 AH
the UB 1280 8AH 6 years old good for 2AH.
On this showing the Yuasa look like the better battery.
Both were used as panel supplies running at .5 A load.

Any opinions on competing SLA batteries?

Most (incl. Yuasa) specify battery life as 3-5 years. Glider use (deep cycles, low temps) means 3 years max in our experience. To get any amperage from 13 years old battery is nothing short of miracle.
