Pacemaker Battery Tester
Highly Accurate Implantable Devices Lithium Battery Tester
Alfamation's Pacemaker Battery Tester (BDU) is an independent instrument that performs quality testing over lithium batteries for implantable devices like pacemakers.
The instrument is Ethernet LAN controlled and autonomously operates the battery contacting the constant current or constant resistance battery discharge cycles. It also monitors and stores battery voltage, sunk current, and temperature values.
The instrument has been developed for parallelism within high-capacity test systems to modularly increase test throughput with the maximum guarantee of system reliability and results consistency.
- Battery discharge autonomous operations
- Easily parallelizable with multiple BDU units without interference
- Extremely accurate and low noise
- LAN controlled
- Fixed resistor or (programmable) Kelvin mode constant current sink
- 7 digits accurate current and battery voltage read-back
- Ending condition after a given mAh capacity discharge, time lapse, or failure
- Time stamped data samples capacity of max. 16 hours of operation @ 1 sample/s
- Electrically actuated contacting system
- Ethernet link allows user to:
- Download the test setup (desired discharge mode, sink current, expected battery voltage, temp range, end-of-cycle condition: time or discharged mAh).
- Read instrument state and statusSet battery test result on the BDU display
- Read the NV memory data samples
- Start a (supervised) calibration process
