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-4422/FP2000/FP4000/FP5000
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.
