Replacement Battery for NK Survey Instruments

The Estry DTM-300 is a 7.2V 3500mAh nickel-metal hydride pack built to match the original specifications for NK DTM-300 and DTM-350 total stations. It replaces part numbers BC-65, BC-60 and 4/UR17650/3500. The pack delivers 25.2Wh of energy and measures 135.9 x 51.45 x 18.0mm at 441.0g. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

For Field Crews Using Compatible NK Hardware

Survey teams and contractors who operate NK DTM-300 or DTM-350 instruments will find this a direct-fit replacement. Buyers whose equipment requires a different voltage, connector layout or form factor should look elsewhere, as this pack is designed only for the listed models and part numbers.

Capacity Decides Runtime Per Charge

The 3500mAh rating at 7.2V determines how long the total station runs between charges. If your workflow demands longer uninterrupted sessions than this capacity provides, you will need a higher-capacity power solution or a spare pack.

Questions about this item

Does the Estry DTM-300 come with a charger or do I need to buy one separately?

The listing describes a single 7.2V 3500mAh Ni-MH battery pack weighing 441.0g; no charger is mentioned, so plan to use your existing charger or purchase one separately.

Should I choose the 3000mAh or 3500mAh version for my DTM-300?

The product title and specifications both state 3500mAh, while the specifications table also lists a 3000mAh model; the 3500mAh version delivers 25.2Wh for longer runtime.

What does the 25.2Wh rating mean when the battery is installed in a DTM-350?

At 7.2V the pack stores 25.2Wh, so a device drawing 1A would run for roughly 3.5 hours, and one drawing 500mA would run for about 7 hours.
