Kastar Battery and LCD Dual Fast Charger for Topcon Total Stations

In this review the Kastar Battery 1 Pack with LCD Dual Fast Charger is evaluated for surveyors and field technicians who need reliable spare power for Topcon total stations and compatible camera batteries. The bottom line: this kit pairs a high-capacity 5800mAh Lithium-Ion battery with an intelligent dual charger so users can recharge two batteries quickly and monitor charge status, making it a practical choice for long days on site.

Key Features

• High capacity: The 5800mAh 7.4V Li-Ion battery delivers extended runtime that reduces mid-project swaps on Topcon models.
• Dual fast charging: The LCD dual fast charger can charge two batteries simultaneously at up to 1000mA per slot to shorten downtime between shifts.
• Wide input range: With AC 100V-240V and DC 12-24V support the charger works in varied jobsite power conditions and with vehicle power sources.
• Smart control: The charger MCU automatically identifies battery voltage and uses intelligent CC/CV charging with pre-charge and 0V activation to protect battery life.
• Visible status: The LCD shows charging status and battery capacity so operators can see when batteries are ready and plan work accordingly.

Who It's For

This kit is aimed at surveyors, construction layout crews, and instrument technicians who use Topcon total stations such as GTS-900A, GPT-9000 series, and related models and who need dependable replacement power in the field. It is also useful for users who need a compact charger that accepts AC or DC input for flexible charging locations.

Professional users who require OEM-branded warranty service or who must match an exact original battery specification for certification may prefer to source a manufacturer original, but most field teams will find the Kastar replacement meets practical needs for runtime and charging control.

Pros & Cons

Pros

• High 5800mAh capacity offers longer operating time between swaps.
• Dual fast charging with LCD reduces downtime and provides clear charge information.
• Intelligent MCU and CC/CV charging protect battery health and enable 0V activation.

Cons

• Not an official Topcon branded part, so users seeking factory original may look elsewhere.
• Charger output is fixed at 1000mA per slot which may be slower than some high-speed proprietary chargers.

Specifications

Our Verdict
