A battery's internal impedance increases with decreasing capacity due to various conditions such as age, ambient temperature, discharge history, etc. The BITE 2P measure impedance values and DC voltage for lead-acid and nickel-cadmium cells up to 7000 Ah capacity. Impedance finds electrical path problems due to plate sulphation, post-seal corrosion, dry-out, and poor intracell and intercell connections. This information lets the operator determine maintenance needs such as:

Cell replacement criteria based on impedance trends

• Jumpering out a cell or two
• Clean and/or re-torque intercell connectors
• Shorten the maintenance interval, etc.

Typical installations that can be tested using the AVO BITE 2P include:

• Electrical power generation plants
• Substations: utility, railroad, industrial
• Telecommunications facilities: CO, Wireline, Wireless, MTSO
• UPS systems.
• Railroad: Signals and Communications, substation
• Aircraft power supplies
• Marine, military
• and many other applications
