The batteries received at least 3 to 5 hours of trickle
charge (time
after charger indicated complete) and preferably 12 to 30 hours of
trickle
charge time. The batteries were taken from the charger, placed in
the GPS receiver, the total timer or elapsed timer was reset to
zero,
and the GPSR was left to run until shutdown due to low batteries.
The receivers were not in a power save mode. The GPSR was
turned back ON and the value of the timer recorded. The words
"Long",
"Medium", "Short" in the comments refers to the length of time of
trickle
charging.

As you can tell by the table above the NEXcell batteries are
starting
to fail even though they are my newest batteries and less than a year
old.
All the batteries above were used in a rotating sequence in three GPS
receivers.
The Maha 1550's were almost always used in the Garmin 12XL, which takes
four batteries, since they were the lowest capacity. Otherwise
all
batteries were cycled through a 12XL, a Venture, and a GPS 76 mostly on
weekends with about eight batteries used per day (the Venture and GPS
76
take two batteries each).
NEXcell may have fixed this problem. See The Great
Battery Shootout! by Dave Etchells at Imaging Resource.
