UBA5 Battery Analyzer & Charger


UBA5 battery analyzer tests, conditions, charges, and generates a test report showing the condition of the battery.

SKU: UBA5PS Category:

The UBA5 battery analyzer tests, conditions, and charges batteries and then generates a test report showing the condition of the battery.

If you are already a battery expert you’ll be pleased to know that the UBA5 has enough features for even the most demanding battery test applications. With its graphical programming interface you can easily design a battery test to do exactly what you want. You can specify the charge method (constant current or constant voltage with peak, timed, or temperature termination) and the charge and discharge currents. You can even use conditional loops in the test. All voltage, current and temperature readings are stored in a standard text results file.

The UBA5’s power lies it its ability to leverage the power of your PC – it has neither display nor keyboard. We keep the UBA5 simple and put the intelligence into the Software on your PC where it belongs.

UBA5 Features

  • Works with all battery chemistries (NiCd, NiMH, SLA, lead acid, lithium ion, lithium polymer and primary batteries).
  • Fully programmable: you can set all charge and discharge currents, voltage settings, and charge algorithms.
  • Includes easy to use and powerful UBA Console software that allows you to graphically design your battery analysis routines and can simultaneously control over 100 UBA5s from one PC.
  • Can run one test cycle to check capacity or thousands to test battery life.
  • Comes with two channels that can each analyze a battery or can be combined with each other or other UBA5s for unlimited charge and discharge current.
  • Stores all results in industry standard text format that you can import into your favorite spreadsheet
  • Battery temperature sensor option: use ours, use yours or use your battery’s built-in sensor.
  • Two year warranty and 30 day money back guarantee.
  • Lead free/RoHS, FCC approval and CE Mark.
  • You will not find a more powerful battery analyzer for less money, we guarantee it.

The UBA5PS comes with a 15 to 24V (switch selectable) 120W 100-240VAC power supply, which works great with the UBA5 for testing batteries from a single cell up to 18.5V. The included power supply has CE and S Mark, it does not have a UL or CSA approval.

If you have a Canadian shipping address, if you require UL or CSA approval, or if you want to use a fixed supply,

1 The small power supply is for powering the UBA5 only, it does not provide the charge current.

2 The maximum battery pack voltage depends on the battery chemistry.


  • All UBA5s come with a serial and USB cable, battery cables, software, manual, and unlimited technical support from our engineering department.
  • All UBA5s can discharge at up to 3A per channel (2.5A for UBA5-60V/UBA5-70V) with a 45W per channel limit
  • All UBA5s can test battery packs down to a single cell, any chemistry
  • All power supplies are universal input, i.e. they work in North America, Europe, or Asia.
