•
Use only Samsung-approved batteries and recharge your
battery only with Samsung-approved chargers which are 
specifically designed for your phone. When a charger is 
not in use, disconnect it from the power source. Do not 
leave the battery connected to a charger for more than a 
week, since overcharging may shorten its life.
•
Do not use incompatible cell phone batteries and
chargers. Some Web sites and second-hand dealers, not 
associated with reputable manufacturers and carriers, 
might be selling incompatible or even counterfeit batteries 
and chargers. Consumers should purchase manufacturer 
or carrier recommended products and accessories. If 
unsure about whether a replacement battery or charger is 
compatible, contact the manufacturer of the battery or 
charger. 
•
Misuse or use of incompatible phones, batteries, and
charging devices could result in damage to the equipment 
and a possible risk of fire, explosion, leakage serious 
injuries, damage to your phone, or other serious hazard.
•
Extreme temperatures will affect the charging capacity of
your battery: it may require cooling or warming first.
•
Do not leave the battery in hot or cold places, (below 0 °C
(32 °F) or over 45 °C (113 °F) such as in a car in summer 
or winter conditions, as you will reduce the charging 
capacity and lifetime of the battery. Always try to keep the 
battery at room temperature. A phone with a hot or cold 
battery may temporarily not work, even when the battery 
is fully charged. Li-ion batteries are particularly affected 
by temperatures below 0 °C (32 °F).
•
Do not place the battery in, on or near areas that may get
very hot, such as on or near a microwave oven, cooking
surface, cooking appliance, iron, or radiator. Batteries 
may explode when overheated. 
•
Do not get your phone or battery wet. Even though they
will dry and appear to operate normally, the circuitry could 
slowly corrode and pose a safety hazard. 
•
Do not short-circuit the battery. Accidental short-circuiting
can occur when a metallic object (coin, clip or pen) causes 
a direct connection between the + and - terminals of the 
battery (metal strips on the battery), for example when 
you carry a spare battery in a pocket or bag. Short-
circuiting the terminals may damage the battery or the 
object causing the short-circuiting.
•
Do not permit a battery out of the phone to come in
contact with metal objects, such as coins, keys or jewelry.
•
Do not crush, puncture or put a high degree of pressure
on the battery as this can cause an internal short-circuit, 
resulting in overheating. 
•
Dispose of used batteries in accordance with local
regulations. In some areas, the disposal of batteries in 
household or business trash may be prohibited. Do not 
handle a damaged or leaking Lithium Ion (Li-Ion) battery. 
For safe disposal options for Li-Ion batteries, contact your 
nearest Samsung authorized service center. Always 
recycle. Do not dispose of batteries in a fire.
