Never swallow.
Always keep the battery out of the reach of infants and young children to prevent it from being swallowed. If swallowed, consult a physician immediately.
Never charge.
The battery is not designed to be charged by any other electrical source. Charging could generate gas and internal short-circuiting, leading to distortion,
leakage, overheating, explosion, or fire.
Never heat.
Heating the battery to more than 100 deg. C could increase the internal pressure, causing distortion, leakage, overheating, explosion, or fire.
Never expose to open flames.
Exposing to flames could cause the lithium metal to melt, causing the battery to catch on fire and explode.
Never disassemble the battery.
Do not disassemble the battery, because the separator or gasket could be damaged, leading to distortion, leakage, overheating, explosion, or fire.
Never reverse the positive and negative terminals when mounting.
Improper mounting of the battery could lead to short-circuiting, charging or forced-discharging. This could cause distortion, leakage, overheating, explosion,
or fire.
Never short-circuit the battery.
Do not allow the positive and negative terminals to short-circuit. Never carry or store the battery with metal objects such as a necklace or a hairpin.
Otherwise, this could lead to distortion, leakage, overheating, explosion, or fire.
Never weld the terminals or weld a wire to the body of the battery directly.
The heat of welding or soldering could cause the lithium to melt, or cause damage to the insulating material in the battery. This could cause distortion,
leakage, overheating, explosion, or fire. When soldering the battery directly to equipment, solder only the tabs or leads. Even then, the temperature of the
soldering iron must be below 350 deg. C and the soldering time less than 5 seconds. Do not use a soldering bath, because the circuit board with battery
attached could stop moving or the battery could drop into the bath. Moreover do not use excessive solder, because the solder could flow to unwanted
portions of the board, leading to a short-circuit or charging of the battery.
Never use different batteries together.
Using different batteries together, i.e. different type or used and new or different manufacturer could cause distortion, leakage, overheating, explosion, or fire
because of the differences in battery property. If using two or more batteries connected in series or in parallel even same batteries, please consult with
Maxell before using.
Never allow liquid leaking from the battery to get in your eyes or mouth.
Because this liquid could cause serious damage, if it does come in contact with your eyes, flush them immediately with plenty of water and consult a
physician. Likewise, If the liquid gets in your mouth, rinse immediately with plenty of water and consult a physician.
Keep a leaking battery away from fire.
If leakage is suspected or you detect a strong odor, keep the battery away from fire, because the leaked liquid could catch on fire.
Never touch the battery electrodes.
Do not allow the battery electrodes to come in contact with your skin or fingers. Otherwise, the moisture from your skin could cause a discharge of the
battery, which could produce certain chemical substances causing you to receive a chemical burns.

Handling
Safety Instructions
This battery contains lithium, organic solvents, and other combustible materials. For this reason, improper handling of the battery could lead to distortion,
leakage*, overheating, explosion, or fire, causing bodily injury or equipment trouble. Please observe the following instructions to prevent accidents.
(* Leakage is defined as the unintentional escape of a liquid from a battery.)
This is a primary battery and cannot be charged. If used in memory or RTC back-up applications, be sure to use diodes to prevent charging from the main
power source or other batteries, and protective resistance to regulate the current as shown in the figure below. Note that the points described below should
be taken into careful consideration when selecting diodes and protective resistance.
