Lithium Battery FAQ:
What is the difference between Lithium batteries and Lithium Ion
There are several important differences. The practical difference
between Lithium batteries and Lithium-ion (Li-ion) batteries is
that most Lithium batteries are not rechargeable but Li-ion
batteries are rechargeable. From a chemical standpoint Lithium
batteries use lithium in its pure metallic form. Li-ion batteries
use lithium compounds which are much more stable than the elemental
lithium used in lithium batteries. A lithium battery should never
be recharged while lithium-ion batteries are designed to be
recharged hundreds of times.
What are the advantages of Lithium Ion batteries compared to other
Lithium-ion batteries have several advantages:
They have a higher energy density than most other types of
rechargeables. This means that for their size or weight they can
store more energy than other rechargeable batteries. They also
operate at higher voltages than other rechargeables, typically
about 3.7 volts for lithium-ion vs. 1.2 volts for NiMH or NiCd.
This means a single cell can often be used rather than multiple
NiMH or NiCd cells.
Lithium-ion batteries also have a lower self discharge rate than
other types of rechargeable batteries. This means that once they
are charged they will retain their charge for a longer time than
other types of rechargeable batteries. NiMH and NiCd batteries can
lose anywhere from 1-5% of their charge per day, (depending on the
storage temperature) even if they are not installed in a device.
Lithium-ion batteries will retain most of their charge even after
months of storage.
So in summary; lithium-ion batteries can be smaller or lighter,
have a higher voltage and hold a charge much longer than other
types of batteries.
What are the disadvantages of Lithium Ion batteries compared with
other rechargeable batteries?
Lithium-ion batteries are more expensive than similar capacity NiMH
or NiCd batteries. This is because they are much more complex to
manufacture. Li-ion batteries actually include special circuitry to
protect the battery from damage due to overcharging or
undercharging. They are also more expensive because they are
manufactured in much smaller numbers than NiMH or NiCd batteries.
Li-ion batteries are becoming less expensive and over time we
should see their price decrease significantly.
Lithium ion batteries are not available in standard cells sizes
(AA, C and D) like NiMH and NiCd batteries.
Lithium-ion batteries also require sophisticated chargers that can
carefully monitor the charge process. And because of their
different shapes and sizes each type of Li-ion battery requires a
charger designed to accommodate its particular size. This means
lithium ion battery chargers are more expensive and more difficult
to find than NiMH and NiCd battery chargers.
Are Lithium Ion batteries available in standard sizes like AA , C
or D cell size?
No, Lithium-ion batteries are not available in standard sizes. We
believe this is because it would be too easy for users to
inadvertently put them in a charger not designed for Lithium-ion
batteries creating a potentially dangerous situation. (If an
alkaline battery is put into the wrong charger it might leak or
even burst, but a lithium-ion battery put into a NiCd or NiMH
charger not designed for lithium-ion, might ignite. Also, because
Li-ion batteries operate at much higher voltage (typically 3.7V per
cell) than the 1.2 to 1.5V of most cell batteries, designing a 1.5V
lithium-ion cell would be expensive.
What is the difference between "name brand" (Canon, Nikon, Fuji,
etc.) Lithium Ion batteries and the other types?
Like prescription drugs there is often very little difference
between name brand lithium-ion batteries and generic lithium-ion
batteries. Camera makers often make very little from the sale of
the camera itself, but have high profit margins for the
accessories, like batteries and flashes. Not all third party
batteries are the same quality as the original battery, but many
(including those which we sell) are virtually identical.
What is the best way to store Lithium Ion batteries?
Lithium-ion batteries can hold a charge for many months. It is best
to store a lithium-ion battery with a partial or full charge.
Occasionally, a lithium-ion battery with a very low charge is
stored for a long period of time (many months) and its voltage
slowly drops to below the level at which its built in safety
mechanism allows it to be charged again. If the battery is going to
be stored for several months it's a good idea to take it out and
recharge it after a few months. Better yet would be to actually use
the battery every few months and then leave it partially or fully
If my camera (or other electronic device) uses alkaline batteries
can I use Lithium Ion batteries?
The answer depends on the particular camera or device. But in many
cases you can not. Because the size, shape and voltage of alkaline
and lithium ion batteries are different they are not
interchangeable. However, some camera makers have designed some of
their cameras in a way that allows the camera to work with either
AA size batteries or CRV3 type lithium batteries. If your camera or
other device can use different types (chemistries) of batteries the
User's Manual should mention it. Also check here to see if your
camera can use the batteries that we carry. Important - There are
several different kinds of rechargeable CRV3 lithium ion batteries
now available under various brands and they cannot use each others
chargers - they are designed as a set and have different charging
requirements. This is one area, unlike NiCD and NiMH batteries that
you need to get one brand of rechargeable battery, and its matching
charger, and stick with it.
Another alternative would be to use an external battery pack of
some sort. These are sometimes available with Lithium-ion
If my camera (or other electronic device) uses NiMH or NiCd
batteries can I use Lithium Ion batteries?
Normally you can not switch between a NiMH or NiCd battery and a
lithium ion battery in a digital camera. There are some devices
specifically designed to use either type of battery, cell phones
are the most common example. If you can use either type of battery,
it should say so in the User's Manual.
How should I dispose of Lithium Ion batteries?
Lithium ion batteries, like all rechargeable batteries are
recyclable and should be recycled. They should never be incinerated
since they might explode. Most places that sell rechargeable
batteries will also accept them back for recycling.
(1) Misusing the battery may cause the battery to get hot, explode,
or ignite and cause serious injury. Be sure to follow the safety
rules listed below:
• Do not place the battery in fire or heat the battery.
• Do not install the battery backwards so that the polarity is

1) Immediately discontinue use of the battery if, while using,
charging, or storing the battery, the battery emits an unusual
smell, feels hot, changes color, changes shape, or appears abnormal
in any other way. Contact your sales location or Panasonic if any
of these problems are observed.
(2) Do not place the batteries in microwave ovens, high-pressure
containers, or on induction cookware.
(3) In the event that the battery leaks and the fluid gets into
one’s eye, do not rub the eye. Rinse well with water and
immediately seek medical care. If left untreated the battery fluid
could cause damage to the eye.
(1) If the device is to be used by small children, the caregiver
should explain the contents of the user’s manual to the children.
The caregiver should provide adequate supervision to insure that
the device is being used as explained in the user’s manual.
(2) When the battery is worn out, insulate the terminals with
adhesive tape or similar materials before disposal.
Be sure to follow the rules listed below while charging the
battery. Failure to do so may cause the battery to become hot,
explode, or ignite and cause serious injury.
- When charging the battery, either use a specified battery charger
or otherwise insure that the battery charging conditions specified
by Green Energy are met.
- Do not attach the batteries to a power supply plug or directly to a
car's cigarette lighter.
- Do not place the batteries in or near fire, or into direct
sunlight. When the battery becomes hot, the builtin safety
equipment is activated,preventing the battery from charging
further, and heating the battery can destroy the safety equipment
and can cause additional heating, breaking, or ignition of the
