Note: Optional NiCd or NiMH 1.2-volt AA rechargeable
batteries can also be used. A charge jack is located
on the right side of the transmitter for convenient
recharging. Spektrum offers rechargeable NiMH
batteries, part number SPM9525, and charger, part
number SPM9526.
CHARGING BATTERIES
If using rechargeable batteries, it is imperative that you
fully charge the batteries prior to each flying session. If
you are using the Spektrum NiMH rechargeable batteries
(SPM9525) and charger (SPM9526), it is necessary to fully
charge the batteries by charging them for 16 hours.
The optional charger (SPM9526) is designed to recharge
your batteries at a rate of 150mA. Do not use this charger
for equipment other than Spektrum transmitters that use
4-cell battery packs. The charging plug polarity may not
be the same and equipment damage can result. During the
charging operation, the charger’s temperature is slightly
elevated. This is normal.

A charging jack is located on the right side of the transmitter.
If rechargeable batteries are used they can be conveniently
charged without removing them from the transmitter using
the charge jack.
CAUTION: Charge only rechargeable batteries.
Non-rechargeable batteries may burst causing injury
to persons and/or damage to property. Never leave
charging batteries unattended.
IMPORTANT: All Spektrum charge jacks are center-pin
negative. This is the opposite of many chargers. Before
using a charger make sure the connector is center-pin
negative. This can be done using a voltmeter. Also
unlike conventional radio systems that use 8 cells to
power the transmitter, the DX5e uses 4 cells. This is due
to the electronics being more efficient. When charging,
be sure to use a charger designed for a 4-cell 4.8-volt
battery pack when charging the transmitter.
TRANSMITTER POLARITY
The center pin on all Spektrum transmitters is negative.
Therefore, the center pin on all Spektrum chargers is
negative, not positive. This is different from many other
manufacturers’ chargers and radio systems. Beware of
improper connections based on “color coded” wire leads,
as they may not apply in this instance. You must make sure
that the center pin of your Spektrum transmitter is always
connected to the negative voltage of your charger for correct
polarity hookup.
