Whether it’s remote controls, toys, or digital camera batteries, you’ll know the status with a single test, ensuring every battery is used to its full potential.

✨ Why Choose the BT-168 PRO?
1. No Power Source Required—Eco-Friendly and Hassle-Free
A revolutionary passive design! Simply insert the battery and push the red slider to activate the test—no need to install an additional button cell battery, making it truly “zero-consumable.”

2. Wide Voltage Range, Universal Compatibility
Not limited to standard dry-cell batteries. The newly upgraded testing range spans from 1.2V to 4.8V, perfectly covering:

1.5V alkaline/carbon batteries (Size 1/2/5/7/C/N)

3.7V lithium batteries (16340 / 10440 / 14500)

1.5V button cells

9V block batteries (dedicated side connector)

3. High-Definition LCD Display, Accurate to 0.01V
Say goodbye to old-fashioned analog meters. The high-definition LCD screen directly displays voltage values (e.g., 1.50V), providing clear readings for an accurate assessment of battery health.

4. Back-Panel Scale for Instant Assessment
A reference scale (Good / Low Power / Replace) is printed on the back of the unit. After measuring the voltage, simply compare it to the scale to quickly determine whether the battery is “Fully Charged,” “Low Power,” or “Needs Replacement.”

5. Compact and Portable, Rugged and Durable
Weighing only 44g and featuring a compact design, it fits easily into a pocket or toolbox. Constructed with an ABS insulated plastic casing, it is sturdy, drop-resistant, and safe against electrical leakage.
