Replacement battery for Fujitsu Laptop
Are the “Aftermarket" batteries
available for my Fujitsu Laptop just as good as the Original Manufacturer
Equipment (OEM) batteries?
That would depend on your point of view. Some people prefer to
stick with the OEM battery because they feel safer with it.
Other people would prefer to go with an aftermarket version,
because in general, they are less expensive then the OEM and in
a lot of cases they have a higher capacity. So just do your
research and make sure that you evaluate your needs before
making this decision.

Fujitsu Laptop Battery useful facts
Breaking In New Fujitsu Laptop
Batteries
New
batteries come in a discharged condition and must be fully
charged before use. It is recommended that you fully charge and
discharge your new battery two to four times to allow it to
reach its maximum rated capacity.
Keeping
your Fujitsu Laptop
Batteries clean
It's a good idea to clean dirty battery contacts with a cotton
swab and rubbing alcohol. This helps maintain a good connection
between the battery and your portable device.
Additional Battery Information
What is a gel cell battery
or sealed lead acid battery?
Gel cell or sealed lead acid batteries have basically the same
chemistry as wet or flooded cell batteries. The batteries'
electrolyte is in a gelatin form and is absorbed into the
plates. The battery is then sealed with epoxy. These batteries
may be used in any position. They are exceptionally leak
resistant. Applications include UPS devices, emergency lights,
and wheelchairs. These batteries contain 2 volts per cell with
common voltages of 4, 6, and 12 volt.
How are battery ratings
used?
- Amp-Hour
battery rating: This is the common rating of a battery.
Amp-hour rating of battery capacity is calculated by
multiplying the current (in amperes) by discharge time (in
hours). Amp-hour battery rating is commonly when describing
sealed lead acid batteries used in UPS systems, emergency
lights and wheelchairs.
For example: a battery which delivers 2 amperes for 20 hours
would have a 40 amp-hour battery rating (2 * 20= 40).
- Cold
Cranking Amperage battery rating: CCA is the discharge load
in amps which a battery can sustain for 30 seconds at 0
degrees F. and not fall below 1.2 volts per cell (7.2V on
12V battery). This rating measures a burst of energy that a
car needs to start on a cold morning. This rating is used
mainly for rating batteries for engine starting capacity and
does not apply to NiCad batteries, NiMH batteries or
alkaline batteries.
- Reserve
capacity battery rating: RC is the number of minutes a new,
fully charged battery at 80 degrees F. will sustain a
discharge load of 25 amps to a cut-off voltage of 1.75 volts
per cell (10.5V on 12V battery). This rating measures more
of a continuous load on the battery.
What is a battery cycle?
Cycle life is measured by the amount of times a battery may be
charged and discharged. Every time a battery is charged and
discharged, it uses one cycle. Cycle life is very important in
battery applications such as laptop batteries and emergency
light batteries. A NiCad battery has a cycle life of 500-1000 or
more cycles.
What are deep cycle
batteries?
Deep-cycle batteries typically feature thick plates with a
high-density active material. The thick battery plates allow for
reserve energy to be stored deep within the battery plate and
released during slow discharge such as trolling or electronic
instrument use. The high-density active material remains within
the batteries' plate/grid structure longer, resisting the normal
degradation found in cycling conditions. They are typically used
where the battery is discharged to great extent and then
recharged such as a battery powered trolling motor on a fishing
boat.
How can batteries be
connected?
Note: When interconnecting batteries (cells), they must be
identical in voltage and amp rating!
-
Batteries may be connected in series. The positive terminal
of the first battery is connected to the negative terminal
of the second battery; the positive terminal of the second
is connected to the negative of the third, and so on. The
voltage of the assembled battery is the sum of the
individual batteries. The batteries are connected: + to - to
+ to - to + to -, etc. The capacity of the battery is
unchanged.
-
Batteries may also be connected in parallel. The positive
terminal of the first battery is connected to the positive
terminal of the second battery, the positive terminal of the
second is connected to the positive of the third; the
negative terminal of the first battery is connected to the
negative terminal of the second battery, the negative
terminal of the second is connected to the negative of the
third and so on. The batteries are connected: + to + to +
and - to - to -. In this configuration, the capacity is the
sum of the individual batteries and voltage is unchanged.
For
example, (5) 6V 10AH batteries connected in series produces a
battery array that is 30 Volts and 10AH. Connecting the
batteries in parallel produces a battery array that is 6 Volts
and 50AH. Ordinary auto batteries are designed in the same
fashion. Six 2-volt cells are arranged in series to produce a
12v battery. Many NiCad batteries are arranged in the same way.
Does overcharging cause
damage?
Overcharging occurs when the total capacity removed has been
replaced by recharging and the battery remains on charge. This
overcharging creates excessive heat that can cause the battery
plates within the cells to buckle and shed their active
material. The battery will react to the overcharge by producing
an excessive amount of hydrogen and oxygen. These gases are the
result of the breakdown of the water molecules within the
electrolyte. The water that has been displaced by overcharging
can be replaced in a serviceable (non-sealed) battery, but, in
the maintenance-free sealed batteries, permanent capacity loss
will result.
Excessive battery discharging can cause damage to a battery. The
amount of discharge a battery can have without damage depends
upon its chemistry. In general, a lead acid battery will not
tolerate as deep a discharge as a NiCad or NiMh battery. Sealed
lead acid batteries function best if they are discharged to only
about 85% of nominal voltage (10.2V on 12V battery).
What is
sulfation of batteries?
Sulfation is the formation or deposit of lead sulfate on the
surface and in the pores of the active material of the
batteries' lead plates. If the sulfation becomes excessive and
forms large crystals on the plates, the battery will not operate
efficiently and may not work at all. Common causes of battery
sulfation are battery inactivity in a discharged condition,
operating the battery at excessive temperatures, and prolonged
under or over charging.
