Lithium Ion Batteries - What You Need to Know About Li-Ion Technology
Lithium
Ion (Li-Ion) battery technology
is one of the fastest growing trends in the
tool community, and certainly for good reason. Lithium Ion batteries have the best
energy to weight ratio, meaning they pack the most power with the smallest
amount of bulk. They also experience no memory effect or, lazy battery effect.
This occurs when a battery can no longer accept a maximum charge for having
been repeatedly recharged without being fully used (a common symptom of Nickel
Cadmium (NiCad) batteries). Li-Ion batteries, conversely, have absolutely no
memory and can continually accept a maximum charge. Additionally, Lithium Ion
batteries have a very slow rate of charge loss while the battery is disengaged.
What is the difference between Lithium
Batteries and Lithium Ion Batteries?
The difference is in the chemistry; a
Lithium battery is a disposable power source composed of lithium metal
compounds - the key word, here, being disposable; Lithium
batteries
can not be recharged. Lithium Ion batteries, on the other hand,
are intercalated, meaning the lithium ion inside the battery moves between two
internal electrodes. This movement, or reversibility of the lithium ion accounts
for the battery's rechargeability.
What are the benefits of Lithium Ion
Technology?
-- Lithium
Ion batteries
hold a lot of power and are surprisingly light-weight,
especially with consideration to other rechargeable batteries.

-- Li-Ion batteries combine single cell technology with a greater energy
reservoir than Nickel Metal Hydride and Nickel Cadmium batteries. They store
more power for their size than both NiCad and NiMH.

-- Li-Ion
batteries
hold their charge for significantly longer than other comparable
batteries, and provide steady power until that charge is completely gone. Other
batteries gradually and consistently loose power as you work. Li-Ion batteries
stay strong until the last push.
Are there disadvantages to using Lithium
Ion Batteries?
The disadvantages with using Li-Ion
battery technology are generally few and far between, and technological
advancements are making them even less so. Manufacturers have recently improved
the Lithium Ion recipe to reveal a more reliable battery. Still, every giant
has its weaknesses:
-- Li-Ion batteries are sensitive to
intense hot and cold temperatures. In extreme temperature conditions, the
battery will degrade more quickly.

-- Li-Ion batteries degrade regardless frequency of use.

-- The Li-Ion battery's built-in computer chip tells the battery to refuse a
charge once the batteries power falls below a certain point. If this occurs,
the battery is beyond repair.
Although these defects are more
applicable to the older Lithium Ion
batteries
, the possibility of seeing these problems is still worth noting.
Fortunately, these said defects are fairly rare, and easily avoided.
-- Store Li-Ion batteries (and other
batteries as well) in a cool, dry place.

-- Use your Li-Ion batteries often.

-- Be certain Li-Ion batteries have a full charge before storing them, and pull
them out every so often to use and recharge. Watch the
batteries
power level to be sure it doesn't fall below the charge limit.
General Li-Ion Battery Tips:
-- On occasion Lithium Ion batteries require
more than one charge (sometimes 2 to even 10) to accept a full charge. The
first time you charge your battery, leave it to charge over night. This ensures
you'll have maximum power for your first use.

-- To maintain proper balance in your battery, leave it charge over night about
once per week for the life of the battery.

-- When buying a new Lithium
Ion battery
, make certain you are buying a fresh one. There's a chance a
battery has been degrading on the shelfs of manufacturer's and distributor's so
be certain you are buying a new one. Most manufacturers provide a date code on
the battery or packaging. Check dates before you purchase, and be confident you
are getting a fresh, high-performance battery.

Are Car Batteries Different From Boat Batteries?
A boat's electrical system starts with a
battery that will supply the electricity for the boat. The system is usually 12
volt DC (direct current), but can be 6 volt, 12 volt or 24 volt depending on
how many and what type of batteries the system is designed for. For this
article, the system discussed is a 12 volt system.
A boat's wiring is a two wire system.
One wire goes from the battery to the light or instrument to be used and a
second wire returns to the
battery
from the light or instrument to complete the circuit. In a Direct
Current system the electricity flows only in one direction. The electricity
flows from the battery to the light and then back to the battery. Each item
used will have its own two wires, one to get power to it, and one to return the
electricity. This is a very simple explanation of how a boat is wired.
The batteries that that are used on a
boat are of 3 basic types. They are a wet cell battery similar to the type used
in a car, a gel cell battery and an AGM or Absorbed-glass mat
battery. All of these types are rechargeable. The battery capacity or how much
electricity it can produce is given by the voltage and amps listed on the
battery. The group size of is the physical size of the battery, the height,
width and length. This lets you get the right size that will fit in space you
have for the battery. The battery designation will be Deep Cycle or Cranking.
A deep cycle battery will put out a
steady current over a long time. A Cranking battery can put out a high amount
of current for a short time to crank a motor over to start it, but it will not
last a long time under continuous use like a deep cycle can. Some batteries,
like AGM batteries, are often designated as BOTH and are dual purpose
batteries. Marine Cranking Amps, Cold Cranking Amps and Reserve Capacity data
is also often given. These numbers tell you they responds under a load
condition and it lets you compare batteries of the same physical size with each
other. The boat motor on the boat will determine what cranking amps are
required to start the motor.
A wet cell battery usually has cells
that you can open and add water to them. When the
battery
heats up under use, water evaporates from them. The cells must always
have the water acid liquid in them covering the cells or the battery dies. The
acid doses not evaporate out, just the water, so water needs to be added
regularly. These wet cell types must also be level or the acid water mixture
will run out. The acid can destroy many things if it leaks out. You can get
sealed, leak proof wet cell batteries to avoid having to add water. Gel Cell
and AGM batteries are sealed and are leak proof. An AGM battery can be stored
in any position and the discharge rate of the AGM type, when it sits unused, is
better than the wet cell and gel cell batteries.
The load the battery will have on it
will determine the type of marine battery that is needed. If it is to be used to
start a motor and run just a few electric items, a cranking battery will work
fine. If it will be used to power a trolling motor and other electronics,
creating a constant drain for an extended period of time, a deep cycle will be
needed. AGM dual purpose batteries are becoming popular because the can handle
both starting and loads well. Another reason they are popular is that they are
sealed and may be stored and used in any position. The AGM's are the first
choice in the marine industry today.
Two batteries or more can be hooked
together to get more power. If two are used together they have to be the same.
If the amp rating is different between the
batteries
one will be damagedHow you hook the batteries
together is important. If both are 12 volt batteries and you hook both +
(positive) terminals together and hook both - (negative) terminals together,
the output between the + side and the - side of the batteries will still be 12
volts, but the amp output doubles. This is called wired in parallel.
If you wire the two together so that the
+ on one goes to the - of the other and then you hook up the things you power
to the free + terminal on one battery and the - terminal of the other battery,
the output will be 24 volts not 12 and the amps stays the same. This is like
two batteries stacked in a flash light. These are said to be wired in series.
A 6 volt battery usually has a higher
amp rating then a 12 volt battery of the same size. By wiring two 6 volt
batteries in series you can get a 12 volt power supply that has greater
amperage then a single 12 volt battery can give. The two do not have to work as
hard to do the same job as the one 12 volt battery does. This is why most golf
carts use 6 volt batteries. It is nice to have options like that.
There are different types of battery
charging systems available. An automatic multistage charging system is best.
Because marine batteries are more expensive the car batteries,
this type will charge the battery without overcharging it. Many sense the type
of battery you have and will pick the correct charging method. This will help
battery last longer.
A car battery can be used on a boat, but
a battery made for the marine industry can give you better service. They are
made to match the load requirements of a boat, they are usually sealed and
leak-proof, and are often a dual purpose high load deep cycle type. The AGM
batteries are the boater's choice. They provide high power with very low
internal resistance compared to conventional batteries and they have two times
the life of conventional batteries.

7 Tips To Maximizing Your Battery Performance
Battery technology seems to have taken a
leaping step recently, allowing electric RC models to go places where once only
nitrous model could go. Leading this innovation are the Li-Po or Lithium Polymer batteries which has
become the standard power source for electric powered helicopters, planes,
cars, boats, and almost every other type of model. However, these batteries are
not exactly cheap, and improper operations will have detrimental effects. Here
are seven tips to maximize your battery performance.
1. Break In New Batteries
Although not as big a deal with newer Li-Po
packs
as it was when NiMh and NiCad batteries were kings, it is still
recommended that you fully charge the battery before first use. Fully
discharging and charging batteries a few times before first flight or will also
give your battery a little bit extra lifetime and power.
2. Keep the pack clean
This is probably one of the most overlooked
aspects of battery operations. It is a good idea to keep the battery pack
clean, and this is especially important for the dean connectors. If the dean connectors
are dirty, the connection may be obstructed and could result in a mid-flight
power failure. The easiest way to clean dirty contacts is simply with alcohol
and cotton swaps.
3. Keep up the battery's health by constant
exercise
Leaving the battery inactive for a long
period of time shorten its life and decrease its total potential. You should
use your
battery
pack at least once every one to two weeks. Fully discharging then
charging the pack will also quell this problem.
4. Take breaks between flights
A fully charged li-po pack has enough power
for a 10-minute flight. However, to fly for ten minutes straight on one pack is
not recommended. If you have two packs, it's best to fly a 5 minute flight,
switch to a fresh pack, fly for another 5 minute, and then switch back to the
old pack. Doing this will greatly increase the life-span on the battery.
5. Do not charge when hot
Never charge the battery pack while it is
still hot. Battery
pack
becomes very hot right after a flight; you must wait until it cools
down before charging it again. Charging a still-hot pack is one of the most
successful ways to shorten a battery's life.
6. Store them well
To store the battery for a prolonged period
(a month or more), the best way to store them is in a clean, dry, cool place
away from metal and heat. Remember also that battery packs loose charge over
time even without usage.
7. Avoid hard impact
Individual cells within a battery pack can
be damaged upon heavy impact which could cause circuit leaks and can be
dangerously unstable. There is also no way to repair a damaged cell. Try your
best not to crash, but of course, we all already do.

10 Advantages of Lithium Polymer Battery for Common Users
Lithium
polymer batteries
have the same technology that is used by liquid lithium
ion batteries. In other words, the anode and cathode are of the same type. The
only difference is that these units use aluminum plastic film and gel
electrolytes. Therefore, these power packs are thinner and lighter but offer a
higher density of energy. In this article, we are going to talk about 10
advantages of these power packs. Read on to find out more.
1. High Energy Density
Compared to nickel-hydride or
nickel-cadmium, lithium-polymer batteries are 50% lighter. But they have the
same degree of energy density, which makes them an ideal choice.
2. Thin Design
Liquid lithium-ion battery features a
customized shell and positive/negative electrodes. And then there is a
technical limit that doesn't allow the batteries to be thinner than 3.6mm. On
the other hand, the polymer cells don't have any such limitations. Therefore,
the thickness of these units can below 1mm.
3. Low Internal Resistance
Unlike liquid batteries, the polymer type
has less internal resistance. Therefore, these batteries can help extend the
time your applications can stay on standby mode. So, this is another great
advantage of these units.
4. Customizable Shape
Based on demand, polymer batteries can be
made thicker or thinner. For instance, for special smartphones, manufacturers
may require thinner batteries. This can help get the most out of the available
space and still enjoy long backup.
5. Good Charge/Discharge Rate
If you use the right type of charger, you
can recharge these units in just two hours. Basically, polymer batteries make
use of colloidal electrolytes that have a stable discharge rate, unlike liquid
electrolytes.
6. High Voltage
A lithium-polymer cell has an operating
voltage of 3.7v on average, which is equal to three nickel-hydride or
nickel-cadmium ones connected in series.
7. High Safety and Performance
The outer shell of these batteries is made
of aluminum plastic. On the other hand, liquid lithium ones come with a metal
shell. Because of the flexible packaging, the deformation of the outer shell
won't cause the battery to stop working.
8. Long Cycle Life
In normal circumstances, a lithium
polymer battery
tends to charge and discharge more than 500 times. Therefore,
you can enjoy long cycle life if you opt for these powerhouses.
9. No Pollution
Also, lithium-polymer units don't contain
harmful metals like mercury, lead, or cadmium. Therefore, they don't cause
pollution unlike other types of units.
10. No Memory Effect
Nickel-cadmium batteries tend to lose their
discharge with the passage of time. On the other hand, lithium-polymer ones
have no such problem. This is also called the memory effect. With time, the
market share of these power packs is rising because of the list of advantages
these batteries offer.
Also, these batteries are used in power
tools and laptops as well. Therefore, these are becoming quite popular as time
goes by.
Long story short, these are just 10 of the
most common advantages of Lithium polymer battery packs. Hopefully, this
article will help you get a deeper insight into these units.
