Visubat is a Portable (8 kg) lead-acid battery test set which is very easy to use with only two cables to connect. The ability to test a bank of batteries without disconnecting them is a valuable advantage in a protection circuit environment as the protection function is not interrupted. The included software creates and maintains a battery database with a graphic presentation of trends, and automatically prepares reports.

  The COTEL Battery Load Unit is used for checking the capacity of storage batteries by discharging them at a constant current to the point where they are considered discharged, and measuring the ampere-hours delivered. Normally used for verifying the capacity of in-service batteries, it can also be used to “run-in” new batteries or those which have been our of service for some time.
