Just how good are those used, sealed lead-acid batteries? [RE-wrenches]

[Hugh Piggott]

<x-flowed>

We have used quite a few secondhand sealed batteries here.  They 
varied a lot in durablility.  Some very fresh ones failed quite soon, 
whereas another set that stood around for a year or two has actually 
given good active service for several more years.  We had to weed out 
the failing units but this was easier because they were used in 2 120 
volt strings.  We only need to check the voltages and pull the weak 
ones when the battery is not doing so well.  Replacements are 
expensive but they have proved worth doing.
