Chapter 3: Getting to Know the EP10

Removing the Battery Pack

Psion EP10 Hand-Held Computer User Manual

3.2.2 Removing the Battery Pack

Refer to “Preparing the EP10 for Operation” on page 9 for more details about removing and installing

the battery.

3.2.3 Battery Swap Time

Assuming the default power saving parameters and battery reserve level have not been altered, battery

swap time is approximately 2 minutes – you will not lose data if the battery is replaced within this

time frame.

To protect data, the safest place to store data is on a microSD memory card or externally to the device on a

USB memory stick or on a PC.

The Suspend Threshold feature allows you to determine the battery capacity at which the EP10 will be shut

down. If left at the default value, Maximum Operating Time, the EP10 will run until the battery is completely

empty; the RAM is only backed up for a short period of time. If you choose Maximum Backup Time, the EP10

shuts off with more energy left in the battery so RAM can be backed up for a longer period of time.

(Refer to “Suspend Threshold and Estimated Battery Backup” on page 106 for details about reserving

battery power for data backup purposes.)

3.2.4 Charging the Battery

Batteries shipped from the factory are charged to approximately 40% of capacity. They must be fully

charged prior to use.

Keep in mind also that, along with the battery, the EP10 is equipped with internal, super-capacitors that pre-

serves data stored on the EP10 for approximately 2 minutes while the battery is swapped.

3.2.4.1 Chargers and Docking Stations

Lithium-Ion battery packs must be charged before use. These batteries can be charged with a variety of

chargers and docking stations. These include:

• Desktop Docking Station (Model No. RV4000) operates as both a charger and a docking station. Oper-

ating as a charger, both the battery installed in the EP10 and a spare battery can be charged

simultaneously. (see “Desktop Docking Station – Model No. RV4000” on page 183)

• Quad Docking Station (Model No. RV4004) can charge the battery of up to four EP10s inserted in the

docking station. (see “Quad Docking Station – Model No. RV4004” on page 186)

Important: Always shut down the EP10 before removing the battery. To safely remove the bat-

tery, press the Power button.

Keep in mind also that all EP10s are equipped with internal super-capacitors that

will save the current data for up to 2 minutes while the battery is swapped.

Important: Do not leave a spare battery to charge for more than 72 hours. Charging for more

than 72 hours may damage the battery or lead to charge capacity reduction.

Important: If the battery is overheated (>60° C) or if the battery capacity is very low (<100

mAh), the unit will not switch on when the Power button is pressed. Under the

above conditions, when AC power is applied, the EP10 will still refuse to power up;

instead, a yellow LED will begin blinking and until the battery is replaced, or in the

case of low battery capacity, the battery is charged to an acceptable level, the EP10

will not switch on.

Important: FOR DETAILED INFORMATION about chargers and docking stations, refer to

Chapter 7: “Peripheral Devices & Accessories” beginning on page 179.
