On 8/30/12 I wrote:



Another data point. After one hour at 14.6 volts, current going into 

the battery is still about 90mA.



         I put this battery on the WMR CBAII at 1.2A load

         and the battery delivered 12.2 a.h.  This value

         is consistent with other evaluations of what appears

         to be a mis-labeled battery.



         I've put it back on the Battery Tender as the sole

         source of charge. Initial rate was 0.85A. After 2

         hours, the terminal voltage has come up from 11.8 to

         12.2 and the rate is 0.75A.  I'll let the Battery

         Tender do it's thing for 24 hours and then repeat

         the cap check cited above.



         I think we're going to find that the 'Tender' is

         putting as much snort back into the battery as it

         will accept . . . but we shall see.
