In-Depth Review & Pictures:
Vencon UBA5: The UBA5 Ultimate Battery Analyzer & Charger package includes the UBA5 pictured below with host of other accessories. UBA5 is a small box with electronic goodies packed inside. Externally the box measures 130 mm in width, 170 mm in length and about 75 mm in height. The box has a beautiful black colored anodized matt finish. All labels over the box are printed in bright yellow color making it easy to look and clear to identify. On top of the box you will notice square shaped attractive design created by a combination of circular and rounded wide rectangular perforations placed for easy airflow. Just below the perforations, you can see through a cooling fan installed for forced air cooling. The temperature controlled variable speed cooling fan dissipates heat generated during high current charge and discharge.

Vencon UBA5 Front Interface: Recognizing the product is easy, Vencon Logo and text "UBA5 Battery Analyzer & Charger" is printed boldly on top of UBA5. There are 2 pairs of color coded banana connector input terminals available. Each pair is identified as Channels. Each pair has clearly marked +ve and -ve polarity. The acceptable voltage and current range also specified. Located centrally across each pair is an indicator red LED. On center of front console, a green indicator power LED is also present.

The red LED indicators come to life when a test is under progress. Green LED will light up as soon as UBA5 gets power.

At the rear end of UBA5, a lot of information and connectors are placed. First to notice on top left is the company name and website. On top right is the model number with Serial Number. At the center of top row is the accessory connector. Since the UBA package was not configured to opt for optional temperature probes, input is blocked with a soft plastic cap. You may, however at any point of time remove it to connect the accessories. At the bottom left standards compliance and approval logos are printed indicating UBA's safety standards. FCC ratings for UBA5 tested to comply for use at home or office. Placed centrally are the two most important RS232 ports. First RS232 male type port is used to connect to another UBA in series to form network. Second RS232 female port can either connect to PC or to next UBA5. One of the best things of having RS232 port is backward compatibility. The logic behind is, since tests and analysis may require you to have a dedicated PC, you need not have a high end PC with USB ports. Any old PC with supported operating system will do just fine. If your PC does not have a RS232 port, you can buy optional USB to Serial adapter or a USB to Serial cable. Vencon has done an excellent job in ensuring that multiple kinds of USB to Serial cables are accepted through various communication modes in the software. There are extensive options in the software to configure the ports accordingly.

At the right most bottom side, a standard 2.1mm DC barrel power plug (center positive) connector is provided. UBA5 accepts DC power supply with Voltage range from 15 to 26 Volts. If you plan to build your own power supply, please ensure to have a well filtered and conditioned power supply with the correct polarity and the voltage is within the specified range. In case if you have connected with wrong polarity, not to worry. UBA5 has built-in reverse polarity protection. There wont be any damage to UBA. If you have bought a UBA5 combo pack, the power adapter is configured properly and you need not worry on any thing. It is suggested to go in for a UBA5 Combo pack if you are an intermediate user. User built power supplies are for advanced users only. Should you require, Custom Power Packs are available at Vencon site.

UBA5 Comparative size: As an indicator of size, placed just above the cooling fan perforations is Sanyo Eneloop AA sized battery.

Vencon UBA5 Package Contents: Apart from UBA5, the UBA5 GP Combo pack includes Software CD, "Where's the Power Switch" Getting Started user manual.

UBA5 GP Combo Pack is configured with 19 V 4.5 Amp Universal Power Supply. The power supply is of SMPS type and works for worldwide Voltage range ranging from 100 V AC @ 60Hz (US) to 230 V AC @ 50 Hz (UK and rest of world). It has international approvals including California's efficiency standard and is lead free.

By default, US power plug cable is included. If you are in UK or in other parts of world you might need an optional UK 3 pin adapter.

UBA5 GP Combo Pack includes the necessary RS232 Serial cable, 2 pairs of high quality banana plug cables with mini crocodile clips are also supplied.

If your PC does not have a Serial RS232 port, you may need to buy additional USB to Serial Cable. You should prefer to buy Vencon recommended USB to Serial cables. Manufacturers such as IO Gear, Belkin (more specifically Belkin F5U103 & Belkin F5U409) or CYS (USC1000) are recommended. The main advantage of using preferred USB to Serial cables is that they are pre configured in UBA Console Software. No additional configurations necessary. However, you can also buy any generic but standards compliant USB to Serial cables. As long as it is has proper software drivers installed and is functioning properly, UBA Console Software will be able to use it. Note that you may need to try different configuration options for the communication & set proper duplex mode if the default mode is not working.

Safety Instructions:
Before beginning installation and testing, please ensure that you carefully read the supplied user manual completely and thoroughly. This is very important step and should not be overlooked no matter how advanced the user is. Here are the important safety warnings taken from the manual.

Batteries are electro-chemical devices that have the potential to burn, explode, or emit harmful chemicals. Please read these safety warnings:

Safety Warnings:
  • Observe battery temperature. Allow cold batteries to warm up and hot batteries to cool before charging. Stop the battery test if the battery becomes very hot.
  • Do not attempt to charge non-rechargeable batteries such as alkaline, carbon-zinc, or non-rechargeable Lithium batteries. Attempting to charge them may result in explosion.
  • Do not short the positive and negative battery terminals together.
  • Do not exceed the battery manufacturer’s recommended charge current and voltage limits. Doing so may damage the battery and result in venting or explosion.
  • Charge and discharge Lithium batteries in a fire proof container.
  • Double check the settings before starting a battery analysis.
UBA Console Software:
One of the best things for using UBA5 is minimal prerequisites and system requirements. A simple basic PC with any flavor of Windows operating system with RS232 port is sufficient to get you started. For extensive analysis, you might want to have a dedicated PC, but there is no need to buy a new one! Any old PC will serve the purpose as long as it is in working condition. In fact, PC's have two RS232 communication ports as a standard. More over UBA Console can run on a Windows 95 operating system. UBA Console can even be operated on a Linux PC through Wine. Most of the standard PCs today have at least one RS232 communications port. If you are using a laptop or your PC does not have a RS232 port, not to worry. As mentioned earlier, UBA Console can easily make use of USB-Serial Adapter cable.

UBA Console CD: The software CD accompanying each UBA5 includes a host of utilities and configurations; most importantly it includes calibration file that is unique to each UBA5 and many sample test BAR files.

Installation: UBA Console installation is a straight forward process. To begin installation, insert the CD in PC's CD drive. Browse to find file "SETUP.EXE" on drives root folder.

Battery Analysis Routine (BAR) Designer:
Before performing battery analysis, you might first want to design the test or use an existing BAR. The BAR Designer tool allows infinite possibilities for you to create test routines. It can be as simple as a simple constant current discharge test to as complex as simulating digital camera taking pictures or it can be even more complex analysis with multiple routines. You can even have endless loop charge/discharge cycle to determine actual cycle life of a rechargeable batteries. The BAR Designer tool is a visual tool that will allow you to perform drag and drop operations. At each step you can click on the "?" icon or click "help" button to get context sensitive help. Every aspect of each module and routine is documented in detailed and in easy to understand language. Here is an example of included IEC NiCd & NiMH test BAR.
UBA5 Console IEC NiCd & NiMH test BAR

First BAR Creation: For the first BAR, we will choose a simple discharge of 0.5 Amp to 0.8 Volts for an Alkaline battery. To create a new routine, we will begin with blank. On the main UBA Console window choose "File --> Battery Analysis Routine Designer..." You will see a window pops up. It is the Battery Analysis Routine designer with a blank template. It has a Begin and End steps with nothing in between.
