How long the spectroradiometer will run with a fully charged battery depends
on many variables including battery age, instrument configuration,
environment, and accessories powered by the accessory power port.
Proper care of the NiMH rechargeable batteries assures long life.
NiMH batteries can store 50% more power than NiCad and do not suffer from
memory effects. Unlike NiCad batteries, NiMH batteries do not use heavy
metals that may have toxic effects. Still, never drop NiMH batteries on a hard
surface.
New NiMH rechargeable batteries can last from 500 to 1000 charges.
When you receive a new battery pack, charge it fully before using it the first
time regardless of it showing full voltage and power. It can take from three (3)
to five (5) charge-and-discharge cycles before the battery pack reaches its
peak performance.
At normal room temperature, NiMH batteries generally lose about 1% of their
charge per day. Higher temperatures increases this loss, while lower
temperatures (40-60F) can reduce this daily loss. The daily charge loss is not a
significant factor if the batteries are used within the first five to ten days after
they have been charged.
