Megger 6121-492 Battery, 5.2 Lithium-ion, For DLRO10 and DLRO10X Testers, DLRO Series

Megger 6121-492 5.2 Ah, 57.7 Wh Lithium Battery Module ONLY

Key Facts

• Battery Type: Rechargeable Lithium-Ion battery pack 5.2 Ah, 57.7 Wh
• For Use With: DLRO10 and DLRO10X ohmmeters
• Interchangeable design: Battery packs can be swapped, allowing continuous testing while a spare battery is charging.
• Fast charging: Reaches approximately 90% charge in 2.5 hours; a full charge takes up to 4 hours.
• Flexible charging options: Can be charged from a 12 V vehicle battery or a 120/230 V AC supply using the 6280-333 charger (not included).
• Built-in battery management: Prevents over-charging and over-discharging while monitoring battery health.
• Battery status indicator: Integrated 10-segment LED display shows charge level from 10% to 100%; a flashing LED indicates less than 10% charge.
• Charging temperature range: Battery should only be charged between 0°C and 40°C.
• Storage and maintenance: Batteries can be safely stored in a discharged state, but charge should be checked before use due to gradual self-discharge over time.
• Temperature impact on lifespan: Continuous exposure to high temperatures reduces battery life significantly; around 5 years at 30°C and approximately 2 years at 40°C.

The DLRO10 and DLRO10X ohmmeters use a lightweight, high-capacity Lithium-Ion battery system designed for reliable field operation and continuous testing. The interchangeable battery packs support fast charging, integrated charge-state monitoring, and built-in protection against over-charging and over-discharging. Users can maintain uninterrupted operation by swapping battery packs or powering the instrument directly from AC mains using the optional DLRO10LPU power supply. Proper charging practices and avoiding prolonged exposure to high temperatures will help maximize battery performance and service life.

*NOTE - Optional line power supply: The DLRO10LPU enables direct operation from 90 V to 264 V AC, 50/60 Hz, ideal for production line or repetitive testing applications. The meter is simply fitted to the instrument to replace the standard battery pack and requires a power outlet. Ideal for repetitive testing applications such as manufacturing production line use.
