How can I maximize the performance of my
There are several steps you can take to help you get maximum performance from your
- Prevent the Memory Effect - Keep the battery healthy by fully charging and then
fully discharging it at least once every two to three weeks. Exceptions to the rule
are Li-Ion batteries which do not suffer from the memory effect.
- Keep the Batteries Clean - It's a good idea to clean dirty battery contacts with
a cotton swab and alcohol. This helps maintain a good connection between the battery
and the portable device.
- Exercise the Battery - Do not leave the battery dormant for long periods of time.
We recommend using the battery at least once every two to three weeks. If a battery
has not been used for a long period of time, perform the new battery procedure described
- Battery Storage - If you don't plan on using the battery for a month or more,
store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH
and Li-Ion batteries will self-discharge during storage; remember to recharge the
batteries before use.
- Sealed Lead Acid - (SLA) batteries must be kept at full charge during storage.
This is usually achieved by using special trickle chargers. If you do not have a trickle
charger, do not attempt to store SLA batteries for more than three months.
The Do’s and Don’ts of Battery
- Fully charge/discharge battery up to 4 cycles before achieving full capacity of
a new battery
- Fully discharge and then fully charge the battery every two to three weeks for
- Run the device under the battery's power until it shuts down or until you get
a low battery warning. Then recharge the battery as instructed in the user's manual.
- Remove from the device and stored in a cool, dry, clean place if the battery will
not be in use for a month or longer.
- Recharge the battery after a storage period
- Ensure maximum performance of the battery by optimizing the device's power management
features. Refer to the manual for further instructions.
- Do not short-circuit. A short-circuit may cause severe damage to the battery.
- Do not drop, hit or otherwise abuse the battery as this may result in the exposure
of the cell contents, which are corrosive.
- Do not expose the battery to moisture or rain.
- Keep battery away from fire or other sources of extreme heat. Do not incinerate.
Exposure of battery to extreme heat may result in an explosion.
My new battery isn't charging. Is it defective?
Usually NO. New batteries come in a discharged condition and must be fully charged
before use. It is recommended that you fully charge and discharge the new battery
two to four times to allow it to reach its maximum rated capacity
It is generally recommend an overnight charge (approximately twelve hours). It
is normal for a battery to become warm to the touch during charging and discharging.
When charging the battery for the first time, the device may indicate that charging
is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries.
New batteries are hard for the device to charge; they have never been fully charged
and not “broken in.” Sometimes the device's charger will stop charging
a new battery before it is fully charged. If this happens, remove the battery from
the device and then reinsert it. The charge cycle should begin again. This may happen
several times during the first battery charge. Don't worry; it's perfectly normal.
