Repeated recharging of a secondary battery can lead to battery deterioration and increase its internal resistance. Problems can intensify when there is a short-circuit in the internal cell leading to voltage drop, overheating and complete battery malfunction. Worst of all, these problems can cause life-threatening fires and other accidents.
Using the large current and anti-interference design, CHT3554A battery tester provides fast, complete and accurate diagnosis in internal resistance and voltage for backup UPS batteries and lead-acid batteries.
Without stopping the instrument, CHT3554A can carry out online measurement and rapid diagnosis of deterioration of the batteries, much increasing the test efficiency. The built-in automatic data storage function can store up to 2400 sets of data.
Powered of Lithium battery and dry battery, CHT3554A can still work in the harsh field and air transport limited areas to facilitate the use of dry-cell battery.
