Battery Tips
NiCd batteries have several characteristics that can affect both their
performance and operating life. The following tips advise you how to
take advantage of these characteristics to get the most out of your
probe’s battery.
• Although NiCd batteries are rated for operation in temperatures
from -20 EC to +65 EC (-4 EF to +140 EF), operating the probe
in extreme temperatures will reduce operating time significantly.
The optimum operating temperature range for these batteries is
+20 EC to +30 EC (+68 EF to +86 EF).
• The battery in the HI-4455 probe does not require periodic "deep
discharges" to reverse the capacity depleting "memory effect"
caused by repeated shallow discharges; however, undercharging
can reduce battery capacity. Therefore, after the charging
procedure is complete, be sure that the battery is fully charged
before resuming field operation.
• If the battery exhibits low terminal voltage during charging, or if it
appears unable to acquire or maintain an appreciable charge,
individual cells in the battery may be shorted or damaged. If, for
any reason, your battery needs replacement, contact ETS-
Lindgren Customer Service for assistance.
