18650 Lithium-Ion Battery
Maintenance Guide
Although uncommon, Lithium-Ion batteries can be com-
bustible, or will leak fluids when not properly maintained,
charged and/or stored. All Lithium-Ion Rechargeable
Batteries require routine maintenance and care in their use
and handling. Read and follow the guidelines to safely use
Lithium-Ion batteries and maximize your battery’s life span.
Overview
DO NOT leave batteries unused for extended periods of time,
either in the product or in storage. When a battery has been
unused for 6 months, check the charge status and charge or
dispose of the battery as appropriate.
The typical estimated life of a Lithium-Ion battery is about
two(2) to three(3) years, or 300 to 500 charge cycles;
whichever occurs first. One charge cycle is a period of use
from fully charged, to fully discharged, and fully recharged
again. Use a two to three-year life expectancy for batteries
that do not run through complete charge cycles.
Rechargeable Lithium-Ion batteries have a limited life and
will gradually lose their capacity to hold a charge. This loss
of capacity (aging) is irreversible. As the battery loses

MAINTENANCE, CARE AND DISPOSAL.

capacity, the length of time it will power the product (run
time) decreases.
Lithium-Ion batteries continue to slowly discharge (self-dis-
charge) when not in use or while in storage. Routinely check
the battery’s charge status. The product user manual typi-
cally includes information on how to check battery status,
as well as battery charging instructions. Product manuals
are available at www.tactxflashlights.com/manuals.
Use TactX-approved batteries and chargers with TactX
Flashlight products. TactX is not responsible or liable
for any batteries or chargers that cause bodily harm
and/or damage to property, battery or flashlight, and
could void the product’s warranty.
If using other brand batteries, be sure to ONLY use bat-
teries that meet the requirements of the TactX flashlight
model as specified in the product manual. Please read
every product guide and instruction manual before op-
erating any rechargeable, battery-powered equipment.
Battery Maintenance
Observe and note the run time that a new, fully-charged
battery provides for powering your flashlight. Use this new
battery run time as a baseline to compare run times for
older batteries you may have purchased. The run time of
your battery will vary depending on the operating power of
the product and the applications under which it will be run.
• Routinely check the battery’s charge status.

• Carefully monitor batteries that are approaching the end
of their estimated life.
• Consider replacing the battery with a new one if you note
either of the following conditions:
1. The battery run time drops below about 80% of the
original run time.
2. The battery charge time increases significantly.
• If a battery is stored or otherwise unused for an extended
period, be sure to follow the storage instructions in this
document. If you do not follow the instructions, and
the battery has no charge remaining when you check
it, consider it to be damaged. Do not attempt to
recharge it or use it. Replace it with a new battery.
Charging
Always follow the charging instructions provided with your
TactX Flashlight product. Refer to your product user manual
and/or online help for detailed information about charging
its battery. The latest version of your TactX product user
manual is available at www.tactxflashlights.com/manuals.
Here are some precautions to take:
• Do not charge or continue to charge batteries after they
have reached full capacity.
• Never allow batteries to come in direct contact with metal
objects or fluids.

NOTE. When you troubleshoot battery issues for dual battery
configurations, test one battery and one battery slot at a time.
A defective battery can prevent the battery in the opposite slot
from charging, leaving you with two uncharged batteries.
Storage
• Charge or discharge the battery to approximately
50% of capacity before storage.
• Charge the battery to approximately 50% of capacity
at least once every six months.
• Remove the battery and store it separately from
the product.
• Store the battery at temperatures between 5°C and 20°C
(41°F and 68°F).
NOTE. Lithium-Ion batteries self-discharge during storage.
Higher temperatures (above 20°C or 68°F) reduce the
battery storage life.
Handling Precautions
• Do not disassemble, crush, or puncture a battery.
• Do not short the external contacts on a battery.
• Do not dispose of a battery in fire or water.
• Do not expose a battery to temperatures
above 60°C (140°F).

• Keep the battery away from children.
• Avoid exposing the battery to excessive shock
or vibration.
• Do not use a damaged battery.
• If a battery pack has leaking fluids, do not touch any
fluids. Immediately dispose of a leaking battery pack (see
Disposal and Recycling in this manual).
• In case of eye contact with fluid, do not rub eyes. Imme-
diately flush eyes thoroughly with water for at least 15
minutes, lifting upper and lower lids, until no evidence of
the fluid remains. Seek medical attention.
Transportation
Always check all applicable local, national, and international
regulations before transporting a Lithium-Ion battery.
Transporting an end-of-life, damaged, or recalled battery
may, in certain cases, be specifically limited or prohibited.
Disposal and Recycling
Lithium-Ion batteries are subject to disposal and recycling
regulations that vary by country and region. Always check
and follow your applicable regulations before disposing of
any battery. Go to http://www.call2recycle.org/locator/ to
find a battery recycling drop-off center near you.
Many countries prohibit the disposal of waste electronic
equipment in standard waste receptacles.

Place only discharged batteries in a battery collection con-
tainer. Use electrical tape or other approved covering over
the battery connection points to prevent short circuits.
