You Can’t See Internal Battery Damage — But You Can Measure It

Here’s a common situation:
A battery shows full voltage, but it dies quickly under load. The equipment isn’t broken — the battery just has no “strength.”

The real culprit is increased internal resistance.

High internal resistance leads to shorter runtime, more heat, and faster aging of the entire battery bank.

A standard multimeter won’t tell you this.
Many users still rely on voltage checks. But a battery with normal voltage and high resistance is already failing.

What This Tool Actually Solves

GD-7100IR is built specifically to measure internal resistance, voltage, and temperature of rechargeable batteries — lead-acid, lithium, etc.
It’s not another multimeter. It does what multimeters can’t:

• No need to disconnect or stop the system

• Ignores contact and cable resistance

• Gives a clear battery health judgment: PASS / WARNING / FAIL

|Real example:

An active UPS system cannot be shut down. With this tester, you simply clamp the leads, measure online, and         get results in about 2 seconds — without interrupting operation.

Why Choose This Over Others?

Common Questions from Real Use

• Q: Why do my readings keep fluctuating?
  A: On-site noise (from UPS, inverters, etc.) often interferes with 1kHz signals. This tester includes a noise frequency avoidance function. It detects and avoids interference near 1000Hz, giving you stable, repeatable readings.

• Q: Does cable length affect accuracy?
  A: It can. But this device uses an AC 4-terminal method and supports zero adjustment. Even with extension cables, accuracy stays within spec after proper zeroing.

Specs You Can Trust (No Hype)

From the manual — not marketing:

• Resistance resolution: 1 μΩ

• Voltage resolution: 1 mV

• Temperature accuracy: ±1.0℃

These are verifiable, repeatable values — essential for production, maintenance, and acceptance testing.

Features

Built for Hands-On Work

• 3.5" color LCD (320×240)

• Direct key access to ranges — no deep menus

• Bluetooth connection to phones or tablets for remote viewing

Data You Won’t Lose

• 10 independent memory banks (A to J)
