How long does the A140 vehicle charger take to fully charge this battery pack?

The A140 12-volt vehicle charger completes a full charge cycle in approximately 5 hours, allowing you to top up between job sites using truck or generator power without returning to the office.

Will this Li-Ion pack work with both my DD300 Connect locator and DA300 transmitter?

Yes, this battery pack is compatible with both the DD300 Connect depth locator and DA300 signal transmitter, allowing you to standardize on a single rechargeable power source across your equipment fleet.

How much weight do I save switching from D-cell batteries to this Li-Ion pack on the DA300?

The Li-Ion pack weighs 2.38 kg compared to 2.70 kg with standard D-cell configuration on the DA300, reducing operator fatigue by 320 grams across hours of daily marking work.

Do I need to purchase the A100 or A140 charger separately?

Yes, the charger is sold separately; select the A100 for AC mains charging at your office or the A140 for 12-volt vehicle charging in the field, depending on your operational workflow.

What is the runtime difference between this Li-Ion pack and disposable D-cell batteries?

The manufacturer specifications confirm this Li-Ion pack delivers equivalent runtime to standard D-cell batteries while providing consistent voltage throughout the charge cycle, eliminating the voltage drop that occurs with alkaline batteries as they deplete.

Can I keep multiple charged packs on hand for back-to-back job sites?

Yes, many high-volume locating contractors maintain 2–3 charged Li-Ion packs and rotate them through the A140 vehicle charger between calls, ensuring equipment is always powered without downtime waiting for recharge cycles.

Quick Answer

What is the Leica Geosystems DD300?

The Leica DD300/DA300 Lithium-Ion Battery Pack is a rechargeable power source compatible with Leica Geosystems underground utility locators and signal transmitters, weighing 2.38 kg and charging via optional A100 or A140 chargers. It replaces disposable D-cell batteries while reducing weight and operational cost per deployment.

FIELD APPLICATIONS

What contractors use this accessories for

Underground Utility Locating

Utility locating contractors use this Li-Ion pack in the DD300 Connect to maintain consistent depth measurement and signal detection through full workdays of marking underground lines. Recharging between job sites eliminates alkaline battery waste and keeps equipment ready for next-call dispatch.

Multi-Call Transmitter Operations

Service techs running the DA300 signal transmitter benefit from the reduced 2.38 kg weight during repetitive marking operations across numerous job sites. The A140 vehicle charger enables 5-hour recharge cycles between calls, keeping the transmitter operational without downtime.

Excavation Damage Prevention Programs

Call-before-you-dig operations performing high-volume daily locates rely on the rechargeable pack to reduce consumable costs and simplify field logistics across dozens of service requests. Consistent Li-Ion voltage output ensures reliable detection performance throughout extended marking sessions.

Telecom and Utility Fleet Operations

Contractors managing multiple locators standardize on Li-Ion batteries to streamline equipment maintenance and reduce per-job power expenses across their service area. Bulk charging via A100 AC chargers overnight ensures all units ready for morning dispatch.

Remote Job Site Operations

Crews working far from commercial power or supply runs use the A140 12-volt vehicle charger to maintain equipment power without returning to base camp. The lightweight pack reduces operator fatigue during long walking routes marking utility corridors.
