• Although NiCd batteries are rated for operation in
temperatures from -20°C to +65°C (-4 °F to +140 °F),
operating the probe in extreme temperatures will reduce
operating time significantly. The optimum operating
temperature range for these batteries is
+20°C to +30°C (+68°F to +86°F).
• The battery in the HI-4453/FP5083/FP4083/FP2083
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.
