I can agree with that (Yuasa that is - I've never even seen Panasonic SLA batteries).  I bought a set of 4 x 100Ah 6V 
Yuasa NP batteries second hand (they'd been used by a radio amateur for field trips) and I charged them when I got 
them home, then ignored them for about three years.  When I went back and checked, they were still reading around 
1.9V per cell, and on recharging have stayed over 2.2V for months afterwards.  I bought a different (but still 
well-known) make of similar batteries, and after charging them and leaving for a few of months they were utterly 
dead, and will not revive, so are going for recycling.  And they weren't cheap!  :-(

So I now always buy Yuasa and Hawker "PowerSafe" which seem to be similarly reliable.
