Charging your
battery:
Rechargeable batteries will perform
better when trickle charged. Rapid or Fast charging can be used with NiCd, NiMH
and Li-IOn batteries, but you must be sure that your charger can handle the cell
chemistry involved. Please consult your charger manufacturer's user guide for
these specifications.
To calculate charge time for your
battery, use the following equations:
|
Slow charger: |
(Cell
capacity in mAh / Charging rate in mA) x 1.4 = Time in hours |
|
Fast charger: |
(Cell
capacity in mAh / Cahrging rate in mA) x 1.5 = Time in hours |
For example if you have a 1700mAh
battery and a charger charging at 700mA, you will need to charge the battery for
approximately 3 1/2 hours.
Exercising your
battery:
Battery life will improve when you
exercise your battery. To exercise a rechargeable battery, first discharge the
battery to 1 volt per cell (or until your equipment complains of "low battery").
(NiCd and NiMH batteries consist of 1.2 volts per cell - i.e. a 4.8 volt
battery contains 4 cells). Finally, charge your battery with a trickle charge
until fully charged. When fully charged a NiCd battery will show approximately
1.35 volts per cell, and a NiMH battery will show about 1.39 volts per cell.
NOTES on Battery
Chemistries:
| NiCd |
Nickel-Cadmium rechargeable
batteries are very durable and reliable. You may slow or fast charge most
NiCd's, but some manufacturers make different types of cells specifically
for rapid charging or specifically for slow charging. NiCd battery
performance is improved dramatically by interspersing discharge pulses
between charge pulses. This is known as "burp" or "reverse load"
charging. This method of charging allows the battery to more efficiently
degass while charging.
NiCd batteries should not be
left in a charger for more than 30 hours. Also, NiCd batteries should not
be subjected to shallow discharge (i.e. using the battery for a short
period of time, then recharging). This type of use may result in
crystalline formation inside the battery which will diminish performance.
This is known as the "memory effect".
|
| NiMH |
Nickel-Metal
Hydride rechargeable batteries are the next level up from NiCd. They
offer up to 40% more run time per volume than NiCd. They are also more
environmentally friendly. The biggest advantage of NiMH over NiCd is
their ability to accept a charge at any time without suffering from the
"memory effect". The best way to charge NiMH batteries is either with the
"burp" charging described above, or with a Delta V terminating charger.
Before charging your NiMH battery, check with the charger manufacturer to
make sure their charger can handle NIMH.
|
| Li+ |
Lithium Ion is the latest
technology in rechargeable batteries for portable equipment. They have
the highest energy density among commercial batteries; twice that of NiCd.
They also have a very low self-discharge rate.
Li-Ion batteries are the most
expensive batteries available commercially. Disposal of lithium based
batteries may cause some concern since any moisture which may creep into
the cell after corrosion could present danger of explosion.
