Kastar 3-Pack Battery and AC Wall Charger Replacement - Long Run Power

In this review the Kastar 3-Pack Battery and AC Wall Charger Replacement is assessed for surveyors and field technicians who need spare power for Leica survey gear. The bottom line: this kit is for users who want a straightforward set of replacement lithium-ion batteries and a compact charger that fits international outlets, providing extended runtime for instruments like Leica ATX, CS, GS and GNSS receivers. It stands out for compatibility across many Leica model batteries and a foldable, travel-friendly charger design.

Key Features

• Compatibility: Works with a wide range of Leica battery models and survey instruments so users can replace depleted packs without hunting for model-specific parts.
• Battery capacity: Each 5800mAh 7.4V battery provides longer operating time in the field compared with small capacity replacements.
• Charger convenience: The included AC wall charger has a foldable flat pin for compact storage and easy transport between job sites.
• Wide input range: The charger accepts AC 100~240V 50~60Hz so it can be used in most regions with the correct plug adapter.
• Charge status lights: LED indicators show red while charging and green for standby or full charge, simplifying monitoring during charging sessions.

Who It's For

This kit is aimed at survey professionals, construction crews, and field technicians who rely on Leica total stations, GNSS receivers and data collectors and need dependable replacement power. The three-battery pack is useful for extended field days or keeping one battery charging while two are in use, and the clear compatibility list reduces risk of mismatch.

Users who require original manufacturer warranty support or a charger with car adapter or European plug included should look elsewhere; the package does not include vehicle adapters or alternate plug types and some buyers may prefer OEM-branded batteries for warranty reasons.
