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 °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 n 4456 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 Holaday Customer Service for
assistance.
