Does not perform
as a 2800 rated battery, but one of the
better Chinese made batteries.

Great variation in cell capacity. All below
rated capacity of 2600.

Not

set made in Singapore, the results are disappointing.
Better value found elsewhere.

Good performance
for a 2000 mAh rated battery, and fantastic
self life for a Ni-MH.

The batteries
were made in May 2006 and tested on
29 Oct. So they were at least 5 months old.
That is fantastic performance for a Ni-MH
battery. Further testing under way.

The Hybrio
are like the Sanyo eneloop, a Ni-MH battery
that hold a charge for long period. Allegedly 80%
for 6 months & 70% over 12 months. Fantastic
performance like the eneloop.

OK, but the battery is too expensive for
