Battery Operation
Your safe uses a 3.7V 18650 rechargeable lithium-ion with a flat
top. A minimum 2000 mAh capacity is required, however 2200
mAh or higher can be used to increase operation time.

Battery Installation

To get started, insert one of your backup keys into the keyhole at
the top of the safe (see Figure A). Push key in and rotate the key
90 degrees clockwise to open the safe.
Locate the battery compartment inside the safe beneath the
control panel (see Figure B).
Remove the battery cover by pressing down on the tab near the
top of the cover.
Insert the 18650 rechargeable lithium-ion battery (included in
accessory box) into the battery compartment. Note that your
Vaultek™ safe automatically detects the polarity of the battery
and can be installed in either direction.
When the battery is inserted you will hear a short welcome tone
and the keypad will light up.
Once you hear the tone replace the battery cover. You are now
ready to program your safe.

Charging the Battery

Your Vaultek™ safe is powered by a rechargeable
lithium-ion battery and comes with a charging kit
which includes an AC power adapter and a micro-USB
cable. Safe and micro-USB cable can be used with all
international power adapters.
Under normal usage, a fully charged battery can last
2 months. To recharge the safe, plug the micro-USB
cable into the micro-USB receiving jack located on the
lower right side of the safe (Figure C) and connect to
a standard USB port or wall outlet using the AC power
adapter. Approximate recharge time is 2.5 hours.
When charging the LED light above the micro-USB jack
(Figure C) will be on.
Due to the powerful features within the MX Series it is
recommended to keep the safe plugged in. A specially
designed VT powerpack is available as a separate
accessory to extend operation time 4 to 5 months.
