EXTERNAL INSTRUMENT BATTERY
Prolonging Battery Life
Extreme heat and cold will affect your battery’s performance. At temperatures above 80°F (27°C), the
battery will discharge more quickly, and in colder temperatures, the battery won’t charge well. Therefore,
it is recommended that the battery is used at room temperature, or between 68°F to 77°F (20°C to 25°C).
The battery must be used at temperatures between 32°F to 104°F (0°C to 40°C).
It is not recommended that the battery is charged in temperatures above 104°F (40°C), and the battery
capacity may be permanently damaged if you use your battery in temperatures higher than 140°F (60°C).
You may damage the battery even more if you charge the device in these temperatures. You may find that
using the battery in a very cold environment decreases the battery capacity. Unlike the effects of a hot
environment, this is a temporary condition. Once warmed, the battery will return to its previous capacity.
Charging myPower ALL Plus
To charge MP3450i, you can use either the included power adapter, an optional car charger (using the same
charging procedure), or a solar panel. The steps to charge with either of these devices are described in this
section.
Charging with a Power Adapter
myPower ALL Plus will charge in four hours when completely empty. The green CHARGE indicator will
turn on after the battery is 80% charged. Therefore, you should view the actual battery capacity before
disconnecting the power adapter to stop charging. (Before using myPower ALL Plus for the first time,
you must charge the device for four hours.)
1. Plug the power adapter into the
DC IN
jack on the end of myPower ALL Plus.
2. Plug the power adapter into a wall outlet.
The red CHARGE indicator will turn on to indicate the battery
is charging and is less than 80% charged.
3. When the green charge indicator turns on, press the Capacity Level Button to view the battery capacity.
If the capacity does not indicate full (blue LEDs on), continue to charge the battery until
the battery capacity indicates full.
4. When the battery capacity indicates full, unplug the power adapter.
