PZ5-BAT External Charger

PZ5-BAT Overview

The PZ5-BAT is an external battery charger for the PZ5 or SIM's 32 Ahr Lithium-ion user-serviceable battery pack. The PZ5-BAT unit is comprised of an off-the-shelf programmable charger that has been pre-programmed for use with the PZ5 battery pack, and a custom connector cable.

Using the Charger

The instructions below are the same for both the PZ5 and SIM devices.

Remove the Battery pack

Before using the external charger, you will often need to remove the battery pack from the device. The PZ5 battery cover is located on the back side and is held on by a single thumbscrew at the top and a simple notch at the bottom.

Unscrew the thumbscrew then lift and pull away the battery cover.
The connector between the batter pack and the device will be immediately visible. Press down on the tab to release the connection then gently pull the battery pack free from the device.

Charge the Battery

Power on the charger by plugging it in to AC power with the provided cable.

Upon power up, verify the display reads "LiPo CHARGE" on the first line and then "3.5A" and "3.7V(1S)" on the second line.

Note

If this message is NOT displayed see Charger Programming Instructions below.
Plug the battery pack into the charger using the custom connector cable.
Press and hold the ENTER (Start) button to begin. The charger will check the battery to verify that it is okay to charge.
When the check is complete, press the ENTER (Start) button again to CONFIRM and then it will begin to charge.
Charging will stop (no numbers changing on the display) when the battery pack is fully charged.

Install a Battery Pack

While the battery pack is charging you can install an alternate pack in the PZ5, or when charging is complete re-install the charged pack.

Connect the pack's cable to the PZ5 cable. The connectors are keyed to prevent miswiring and snap in place when securely connected.
Gently slide the battery into the unit. Ensure that the cable is tucked inside the opening.
Line-up the tabbed end of the cover with the notch at the bottom of the opening and slide it into position.
Use the thrumbscrew to securely attach the cover.
