Kastar 4-Pack Battery and AC Wall Charger Replacement for Leica Gear

Our review examines the Kastar 4-Pack battery and AC wall charger replacement for Leica survey equipment and related GNSS receivers. The bottom line: this kit is aimed at field surveyors and technicians who need multiple spare power sources to keep total stations and GNSS units running through long workdays. Its single biggest selling point is capacity and convenience - four 7.4V 5800mAh lithium-ion batteries paired with a compact foldable AC charger provide extended runtime and an easy charging option while traveling between sites.

Key Features

• High capacity batteries: Each 7.4V 5800mAh lithium-ion cell provides long runtime so instruments like total stations and GNSS receivers can work through extended field sessions without frequent swaps.
• Four-pack convenience: Supplying four batteries in one package reduces downtime on busy projects by keeping multiple charged spares on hand.
• Wide charger input: The included AC charger accepts 100~240V 50~60Hz input for use in varied mains environments when traveling domestically or internationally.
• Simple LED status: The charger uses a red LED while charging and a green LED for standby or full-charge, making it easy to check status at a glance in the field office.
• Compact charger design: The AC wall charger has a foldable flat pin for easy storage and transport in a tool bag or case.

Who It's For

The Kastar pack is best for surveyors, contractors, and rental fleets who operate Leica ATX, TS, or GPS series equipment and need multiple spare batteries to rotate through large job sites. Its compatibility list covers many Leica battery and charger model numbers, so it suits shops that maintain different Leica instruments and want one replacement pack to cover them.

Those who should look elsewhere include users who require car adapters or European plug accessories included in the box, since the package only contains a single AC charger and explicitly excludes car or European plugs. If single-battery purchases or OEM-brand batteries are required for warranty reasons, this aftermarket pack may not meet that need.

Pros & Cons

Pros

• High 5800mAh capacity per battery keeps field gear powered for longer sessions.
• Four batteries included reduce operational downtime and simplify logistics.
• Charger accepts wide voltage range so it works across 100~240V mains systems.
• LED charge indicator and foldable flat pin add convenience for storage and status checks.

Cons

• Package does not include car adapter or European plug, which some users may need separately.
• As an aftermarket replacement, compatibility is broad but users who require OEM parts for warranty reasons may prefer manufacturer batteries.
