Battery Charging
216 Psion Teklogix 7530 G2 Hand-Held Computer User Manual
6.4 Battery Charging
Note: Initially, new batteries that have been fully charged may indicate slightly
less than 100% charge. No special conditioning is required. The full
capacity of the battery will reach 100% after 5 cycles through the charger.
It can take from 1.5 to 4 hours to charge a battery. The 7530 G2’s intelligent
charging system protects the battery from over-charging by terminating the charge
process when the battery is at maximum capacity.
Important: To preserve battery integrity, the charger will proceed with a
charge only when the battery temperature falls between 5° C and
39° C (41° F to 102° F). If the battery is too hot or cold, the
battery status LED flashes yellow and the charge is suspended.
6.5 Gang Charger
The gang charger is designed to charge up to six 7530 G2 Lithium-Ion batteries at
one time. Your charger is shipped with the appropriate IEC mains power cord. If the
supplied power cord is incorrect for your country, contact Psion Teklogix for
assistance (see Appendix A: Support Services And Worldwide Offices).
Note: The gang charger is shipped with a user manual. It is critical that this
manual be reviewed for additional information and updates.
6.5.1 Installation
The gang charger can be wall mounted using the wall mount kit, Model # HU3106,
or it can be operated on a flat surface. Install the charger in an area that is free from
excessive dirt, dust and contaminants. The ambient temperature must be in the range
5° C to 39° C (41° F to 102° F). The charger will not charge batteries outside
of this temperature range. For maximum performance, it is recommended that
the charger be operated at room temperature – a temperature range between
18° C to 25° C (64° F to 77° F).
The charger can consume up to 2A @ 120VAC or 1A @ 240VAC. Check to ensure
the mains circuit supplying the charger is adequate for this loading (especially if
several chargers are being powered from the same circuit).
After unpacking the unit:
• Visually check the charger for damage.
• Install the IEC power cord and apply power.
