TA521 - Lithium Battery¶
- Manganese dioxide lithium button cell, 3 V, 560 mAh
- Primary cell, non-rechargeable
Purpose
The TA521 lithium battery is the only applicable battery for the AC500 Processor Modules PM57x (-y), PM58x (-y) and PM59x (-y) and PM56xx: PM56XX
Purpose
The processor modules are supplied without lithium battery. It must be ordered separately. The TA521 lithium battery is used for data (SRAM) and RTC buffering while the processor module is not powered.
See AC500 Battery: AC500 Battery
The CPU monitors the discharge degree of the battery. A warning is issued before the battery condition becomes critical (about 2 weeks before). Once the warning message appears, the battery should be replaced as soon as possible.
Handling Instructions
- Do not short-circuit or re-charge the battery! It can cause excessive heating and explosion.
- Do not disassemble the battery!
- Do not heat up the battery and not put into fire! Risk of explosion.
- Store the battery in a dry place.
- Replace the battery with supply voltage ON in order not to risk data being lost.
- Recycle exhausted batteries meeting the environmental standards.
Battery Lifetime
The battery lifetime is the time, the battery can store data while the Processor Module is not powered. As long as the Processor Module is powered, the battery will only be discharged by its own leakage current.
Note
To avoid a short battery discharge, the battery should always be inserted or replaced while the process module is under power, then the battery is correctly recognized and will not shortly discharged.
