Lamar D50 BETA D-50, BATTERY TESTER

The **Lamar D50 BETA D-50 Battery Capacity Analyser** (P/N **D50**) is a self-contained aircraft battery testing unit designed to evaluate the discharge capacity of compatible rechargeable aviation batteries. Part of Lamar's Power Products BETA range, the D-50 supports sealed and vented lead-acid batteries and nickel-cadmium (Ni-Cd) batteries across a range of battery voltages. The analyser provides adjustable **constant current discharge from 0.1 to 50 A**, allowing technicians to perform controlled battery capacity tests according to applicable battery maintenance requirements. The unit features a selectable low-voltage cut-off and an adjustable digital discharge timer ranging from **1 to 999 minutes**. During testing, the analyser monitors battery voltage and discharge current to assess whether the battery maintains the required voltage for the specified test duration. At the end of the test, an audible alarm sounds and the digital meters and timer retain their readings for battery capacity evaluation. Integrated **Accept and Fail indicators** provide a clear pass/fail assessment. Designed for aviation maintenance workshops and battery servicing facilities, the BETA D-50 operates from selectable 115 V or 230 V AC power supplies. --- ## Applications Suitable for applicable: - **Lead-Acid Aircraft Batteries** – Discharge capacity testing of compatible sealed and vented batteries - **Nickel-Cadmium Aircraft Batteries** – Constant current discharge testing of compatible Ni-Cd batteries - **Aircraft Battery Capacity Testing** – Evaluation of available battery capacity against specified maintenance requirements - **Aircraft Battery Condition Assessment** – Verification of battery discharge performance - **Aviation Maintenance Workshops** – Battery inspection, testing and maintenance operations - **Ground Support Batteries** – Capacity testing of compatible rechargeable batteries - **Aircraft Battery Servicing** – Controlled discharge testing using selectable current, voltage cut-off and test duration Battery chemistry, voltage, capacity rating, discharge current and cut-off voltage must be confirmed against the applicable battery manufacturer's instructions and Lamar operating manual before testing. --- ## Why CJ Aerospace?
