SPECTRO SPECTROSCOUT Original Operating Instructions page 9

Please observe the relevant national and regional regulations.

A fully charged lithium battery can last up to approximately 5 hours

(continuous operation). The exact battery life depends on the sample
throughput per time unit and the selected measurement parameters.
If a lithium battery is empty, it must be recharged after one week of storage at

the latest.
If lithium batteries are to be stored over an extended period, they should be

charged to 50%-70% of their capacity. The optimum storage temperature is
15° to 20°C (59° to 68°F); under these conditions, the stored lithium battery
should be recharged at the latest after 3 months.
If the storage temperature exceeds 20 °C (68 °F), the battery will self-

discharge more quickly. In this case, it needs to be recharged at shorter
intervals. (40°C (104°F) ~ 2 months, 60°C (140°F) ~ 1 month).
The lithium batteries include an electronic safety system that checks the state

of charge of the individual cells. As a result, it continuously withdraws energy
from the lithium batteries. Consequently, there is a risk of deep discharge if a
used lithium battery is stored that does not have the minimum charge.
If one of the cells in the lithium batteries is already deep-discharged, the

integrated electronic system prevents the recharge of the lithium batteries for
reasons of safety.
Note
Fully charge the lithium battery of the SPECTROSCOUT prior to using it for

the first time.
The lithium battery can only be charged at a temperature ranging from 0°C to

45°C (32°F to 113°F). A protective circuit within the instrument prevents the
battery from charging, unless the temperature is within this range.
