The BITE2 and BITE2P battery impedance testers determine the condition of lead-acid and nickel-cadmium cells up to 7000 Ah. An advanced feature set has been developed that includes Pass/Warning/Fail calculations based on a user-entered baseline value, advanced printing functions, and more. The BITE2P consists of both a transmitter and a carrying case for all standard accessories and some optional accessories. The BITE2 and its accessories fit into a sturdy canvas case with a shoulder strap.
The instruments work by applying a test current across the battery string while on-line, then measuring the total current (AC ripple and test current) and the voltage drop of each cell/jar. It then calculates the impedance. They also measure DC voltage and interconnection (strap) resistance to help determine the overall condition of the entire battery string's electrical path from terminal plate to terminal plate.
The BITE2 and BITE2P receiver stores the readings in its internal memory. These measurements, along with other maintenance data such as ambient and pilot cell temperatures and AC ripple current, assist in determining the overall condition of battery systems. Megger recommends that impedance measurements with the BITE2 or BITE2P be made part of a battery maintenance program with readings taken and recorded semi-annually for flooded batteries and quarterly for VRLA.
Unlike load cycle testing that involves substantial downtime and repeated discharges, using these instruments requires no battery discharge, nor does it stress the battery in any way compared to other techniques. With a test time of less than 20 seconds for each cell and intercell connector, one person can easily, quickly, and precisely measure internal cell impedance, DC terminal voltage, and intercell connection resistance without taking the battery system off-line.
Naturally, everything you need to perform these tests is included with the basic instruments. There is a full line of optional accessories to enhance the capabilities of the BITE2 and BITE2P and both have the ability to download to a PC for data interpretation. Additionally, the BITE2P has a built-in printer so you can review the active test and also leave a hard copy record at the site.

Frequently Asked Questions
Can I test NiCD batteries?
When testing NiCD batteries, there are 2 challenges. The battery post is typically not assessable. Measurements must be taken on the hardware. Therefore, when using a battery tester with a duplex lead the test current is injected through the hardware. This causes a voltage drop across the hardware. The resulting ohmic measurement will include the hardware. In the case of stainless steel hardware, this value can be greater than the ohmic value of the battery. The BITE2 injects the test current through the entire string. This means there is no voltage drop across the hardware. The measurement can then be taken on the hardware, when using the BITE2.. A NiCD battery tends to maintain both its voltage and ohmic value throughout most of its discharge. This means if you measure a NiCD battery with a significantly higher impedance, then this is evidence that there may be an issue with this battery. However, if the battery does not have a high impedance, this does not mean the battery is good. A discharge test is required to determine this, when using NiCD batteries.
Can I retest a cell and or an inter-cell connection?
Yes. When the receiver asks you "Test Complete", reply NO. By using the arrows you can scroll up and down to each measurement. Go to the measurement you wish to repeat. Pull and release the trigger. You can now retake the measurement. NOTE: All measurements are made in cell / strap combinations. This means you must re-take both the cell and the strap measurement. You can scroll up and down through the test and re-take any measurements you wish. When complete scroll to the last battery. Now when prompted "Test Complete" select YES. Once the test is complete, no changes can be made to the recorded measurements.
Can I get pass, fail indications on the BITE2 receiver?
During the receiver setup, you are prompted "Baseline". Select Yes. Now use the up and down arrows to select the desired numbers and the ENTER key to move from space to space. You will need to enter the baseline value, plus the warning and fail alarms.
