CELL CHECKER Lead Acid Pulse Load Battery Tester - US Made

Model CELL03 tests the State of Charge and Battery Condition for 2V, 4V, 6V, 8V and 12V Lead Acid Battery Types (SLA, AGM, Gel, Wet)
  • Made and serviced in the U.S.A.
  • Simple to operate, genuine Pulse Load testing with test results in 15 seconds.
  • Measures battery performance under load, not just voltage or internal resistance.
  • Computes State of Charge for lead acid battery types (SLA, AGM, Gel, Flooded).
  • Tests battery condition - quickly and easily identifies weak or failing batteries.
  • Tests 2-volt, 4-volt, 6-volt, 8-volt or 12-volt batteries up to 200A.
  • Ideal for battery management and cell matching - reduce costs and increase reliability.
  • Test capability modes:
    • 2-volt [2-25AH].
    • 4-volt [2-25AH].
    • 6-volt [1-4AH, 5-15AH, 16-50AH, 20-100AH, 50-200AH].
    • 8-volt [2-20AH, 20-100AH] 12-volt [1-4AH, 5-15AH, 16-50AH, 20-100AH, 50-200AH].
  • Accurate pulse load testing.
  • Identifies weak or failing batteries in alarm systems.
  • Tests battery performance – not just voltage/internal resistance.
  • Power (internal): 4 x AA batteries.
  • Dimensions: 9.25 x 6.25 x 2 inches.
  • Weight: 32 ounces / 908g.
  • UPC: 5060184300926.

Accessory Pack for Cell Checker (CELL-PAC)

The SDI CELL-PAC accessory kit includes a protective soft case, hanging strap, and a strong magnet. The protective soft soft case comes equipped with a Velcro® flap. The hanging strap has a quick release buckle which helps with quick fastening to conduit, pipes, ladders, etc. The magnet enables attachment to metal surfaces like alarm panels, access covers etc.


  1. Turn on power switch (located to the right hand side of the unit)
  2. Select the type of battery to be tested by pressing the MODE key until the LED next to the correct battery type is illuminated
  3. Connect the test leads to the battery terminals ensuring a good connection with the red lead connecting to the positive terminal (+) and the black lead connecting to the negative battery terminal (-)
  4. Press the TEST key
  5. LEDs will flash in sequence indicating the test is in progress. When the test is complete one LED will remain lit indicating the battery’s state of charge or remaining capacity
  6. Make two tests at five second intervals to verify that the battery has stabilized and is delivering consistent power
  7. Turn off power switch after battery is disconnected


Battery voltage alone is not a reliable parameter for determining remaining capacity and condition; it also does not indicate whether the battery will be able to deliver power when placed under load. Rather than simply displaying a voltage reading, cellchecker™ determines a battery’s remaining power capacity by measuring its ability to maintain voltage levels while under load. The tester then makes an assessment based on these readings and displays the remaining percentage capacity of the battery.

Pulse load testers verify that a battery can deliver power by actually making it deliver power. The duration and repetition of the load test cycle varies depending on the battery type being tested. Factors that are considered when determining the size and duration of the pulse load are battery design (high rate or low rate), battery chemistry, and the battery’s typical application. This helps ensure that the power demand on the battery during the pulse load test will be comparable to what the battery experiences under normal operation conditions.

“…it is imperative to determine whether a battery would be able to sustain the necessary load for the required amount of time without failing. Practically, only load testing can achieve this properly…”

“…battery testers that test a battery under no load do not accurately simulate the battery’s performance in operating conditions…”

“…under load, the battery shall perform in accordance with the battery manufacturer’s specifications…” "Each battery shall be inspected and tested to confirm operability..." NFPA 72 Chapter 14 ( CAN/ULC-S536-
