D.T. Systems Micro-iDT PLUS - Manual (Page 11)

Micro-iDT™ PLUS Series collars are equipped with
rechargeable Nickel Metal Hydride (NiMH) batteries,
which are not memory sensitive and do not require
depletion before recharging. Although batteries come
partially charged from the factory, it is recommended
that they are given a full charge (about 12 hours)
before initial use.
The transmitter uses a 9-volt replaceable battery (not
included). Be sure to pay attention to the “+” and “-”
charges when inserting the battery.
Battery Charging Procedure
1. Make sure the unit is off.
2. Plug the charger into a
standard electrical outlet.
3. Connect the splitter cable to the charger and plug
an end into the unit.
4. Charge the batteries for up to 12 hours.
5. After charging, disconnect the battery charging
cable from the receptacle, securely replace the
rubber battery receptacle cover, and test unit.
WARNING: DO NOT CHARGE WHILE UNIT IS WET!
NOTE: Rechargeable batteries typically last about 2-5 years
on average depending on use and care. Do not over-
charge your unit (12 hour max charge time). Fully charge
and test your unit once every 4-6 weeks when storing. Do
not store your unit in extreme heat/cold or moist/humid con-
ditions. Keep batteries away from flammable substances.
