NOTE: Batteries stored for more than a year or stored in excessively hot environments may experience a higher failure rate.

NOTE: When using rechargeable batteries, do not use any battery with a fully-charged rating of greater than 9v, for example, 9.6V

ULX Transmitters use a DC-to-DC converter, which require a minimum 6 V to operate. It the battery does not provide this threshold voltage, the transmitter will not operate.
