Getting Familiarized with the SIMATIC Field PG P4
The rechargeable battery has a typical service life of 300 charging cycles, i.e.
under normal conditions of use it can be charged and discharged within six months
after you have purchased the PG. Capacity loss beyond this time is
technology–related, and warranty is therefore excluded by all manufacturers of
similar devices. We recommend you replace the battery pack if the performance
deteriorates significantly. Always use the original Siemens battery packs.
Notes on the service life of your battery pack:
• The battery pack should always be fully charged / discharged – same as the
calibration of the battery.
• Frequent use: The more often you use the battery pack, the faster it reaches
the end of its service life. The Lithium / Ion battery pack has a typical service
life of 300 charging cycles.
• If the computer is usually operated by means of the power adapter, you should
fully load the battery pack and remove it for separate storage.
Warning
