ACT D4000 Universal Battery Tester

The new ACT D4000 Universal Battery Tester from ACT is a clever, multi-tasking solution for testing a wide range of rechargeable battery types, voltages and capacities.  It will test ALL rechargeable batteries - including lead-acid, lithium-ion, nickel-cadmium and nickel metal hydride - with voltages between 2.4V and 12V, with capacities above 4Ah.  It's an ideal tester for batteries used in: 

• stand-alone emergency lighting luminaires
• security and fire alarm panels
• battery powered tools, bicycles and toys etc

How it works

Once connected to the battery terminals, the D4000 automatically detects the battery voltage then selects the correct resistance load to discharge 1Ah from the battery.

During the test, if the battery voltage drops below a critical monitored level, a red ‘fail' LED will latch on.  Provided the battery voltage remains healthy, a green ‘pass' LED will show at the end of the test, a yellow LED flashes continuously throughout the test period.  The fan-cooled D4000 can be used repeatedly to load test new and used rechargeable batteries with capacities above 4Ah.

How long it takes

The D4000 will identify a healthy battery normally between 7 to 10 minutes, but will only take just 1 minute to identify a defective battery.  A low capacity battery will be identified normally within 3 minutes.  This makes it possible to quickly identify a good battery without having to wait for the full 1Ah discharge test to be completed.
