Battery Maintenance: 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 at least 3 months.
To recharge the safe, plug the micro-USB cable into the micro-USB receiving jack
located on the back side of the safe (Figure D) and connect to a standard USB port
or wall outlet using the AC power adapter. Approximate recharge time is 2.5 hours.
The LED next to the receiving jack on the back of the safe (Figure D) will glow
YELLOW indicating charging and GREEN indicating charged.
Battery Maintenance: Charging Tips!
After installing the battery, use the charging kit provided to charge the unit 100%.
The charging kit can also function as an external power supply, which means you can open your safe even when
the battery is depleted.
Leaving your safe plugged in continually will not harm the safe or battery. However, to preserve battery life we
suggest that you unplug occasionally to allow the battery to cycle down.
A specially designed Vaultek powerpack is available as a separate accessory to extend operation time.
®
The adapter used to charge the battery should output 5V/2000mA or above when using micro-USB cable.
See the FAQ section for additional information about the battery.

Battery Maintenance: Testing the Battery Power
To check the battery level, press and hold the '5' key on the keypad for 3 seconds. The keys will glow GREEN or
RED to indicate the battery level:
Remaining Battery Capacity Level
If 4 keys glow green: 80%-100%
If 3 keys glow green: 60%-80%
If 2 keys glow green: 40%-60%
If 1 key glows green: 20%-40%
If 1 key glows red: 10%-20%
D
If 1 key blinks red: less than 10%
Battery Maintenance: Low Battery
If the first key blinks RED several times and you hear several rapid beeps when opening the safe, your battery
level is critically low and your safe needs to be charged immediately.
Battery Maintenance: Soft Rest Tip
In the event the battery dies or a soft reset is performed (battery removal and installation) the safe will restore
default settings for interior light, sound, and Alert of Manual Unlock feature. These settings will need to be
readjusted, however the master code and fingerprint scanner will not be affected.
IMPORTANT! Use a 3.7V 18650 rechargeable lithium-ion battery with a flat top. A minimum 2000 mAh capacity is
required, however 2200 mAh or higher can be used to increase operation time.
IMPORTANT! The adapter used to charge the battery should output 5V/2000mA or above when using micro-USB
cable.
