Replacing Nimh Batteries - Fluke Datapaq TP3 User Manual

The logger intelligently monitors the battery, ensuring it is never overcharged.
Thus, by leaving the charger connected to the logger, the logger will always be on
charge and ready for use. This will not damage the battery or reduce its service life.
Note that the logger will not charge while collecting data. The charger can be
connected to the logger while logging, but charging will stop as soon as data-
New batteries – or ones which have been unused for several months – should
be charged for 24 hours before use.
NiMH batteries discharge slowly even when not in use and will need
charging if left for more than three weeks.
If the logger is not in regular use, the battery should be charged at least
every 3 months. If this is not done, the battery may drain to a level where it
Where batteries are too cold (below 0°C/32°F), too hot (over 45°C/113°F) or
too deeply discharged, they must be preconditioned before fast charging can
begin. Pre-conditioning (slow charging) occurs automatically if it is required, and
is shown by the battery status LEDs (steady yellow + flashing red). If the battery
is still being pre-conditioned after 5 hours, there may be a fault; contact Fluke
Process Instruments.

Replacing NiMH Batteries

chemical skin burns. Never use a damaged battery-pack (e.g. with split in
Keep battery-packs clean and dry. Clean dirty connectors with a dry, clean cloth.
Do not put battery-packs near heat or fire, nor in sunlight.
The logger employs non-volatile memory, so – even when the battery is
removed and replaced – stored data will not be lost.
Service life of the rechargeable NiMH battery is up to about 500 charge/
discharge cycles.
