100A Analog Battery Load Tester | 6V 12V Handheld Battery Tester with CCA Chart

100A Analog Battery Load Tester — Professional 6V/12V Handheld Battery Analyzer with CCA Chart

Simple, reliable, and built to last — the Platrex 100A Analog Battery Load Tester gives mechanics and DIYers a fast, no-fuss way to diagnose battery health on any 6V or 12V lead-acid battery. With a color-coded analog dial, a built-in CCA reference chart, a rear Battery Analysis guide, and a classic toggle switch for load activation, this tester delivers professional-grade results in a compact, portable package. No screens to read, no software to update — just connect, load, and read.

Key Features

• 100A Load Capacity: Accurately simulates engine cranking conditions for true battery health assessment
• Color-Coded Analog Dial: Clear Bad / Weak / OK / Good / Charging System zones for instant visual diagnosis
• Built-in CCA Reference Chart: Battery Capacity in Cold Cranking Amps (CCA) table on the meter face — 200 to 1000 CCA range with corresponding Load Volts and Min Crank Volts
• Starter Test Reference: Load Volts vs. Min Crank Volts table for engines under 3.6L (200 CID)
• Toggle Switch Load Activation: Classic metal toggle switch for controlled, reliable load test activation
• Rear Battery Analysis Guide: Detailed Battery Condition chart covering OK (Green Band), Weak or Bad (needle steady), and Weak or Bad (needle deflecting) — plus Temperature Compensation table
• Heavy-Duty Copper Clamps: Large copper alligator clamps with insulated red/black handles for secure, spark-free connection
• Ventilated Steel Housing: Louvered steel body with integrated carry handle for heat dissipation and portability
• No Power Required: Fully passive design — no batteries or external power needed
• 3-Step Operating Instructions: Printed on front panel for quick reference

Battery Analysis Guide (Rear Panel)

• OK (Green Band): Battery voltage holds above minimum threshold after 15-second load — battery is good
• Weak or Bad (needle steady): Battery may be defective or not fully charged — recharge and retest; replace if condition persists
• Weak or Bad (needle deflecting): Battery may have a bad cell — voltage drops during load; replacement recommended
• Temperature Compensation: Decrease battery rating by 1 step at 0°F and 2 steps at -30°F for accurate cold-weather diagnosis

2. Read the open-circuit voltage on the analog dial (toggle switch OFF)
3. Flip the toggle switch to ON and hold for up to 15 seconds
4. Read the needle position against the color-coded zones and CCA chart
5. Refer to the rear Battery Analysis guide for detailed diagnosis
6. Flip switch OFF and disconnect clamps

Applications

Ideal for cars, vans, RVs, trucks, motorcycles, and farm vehicles. Suitable for automotive workshops, roadside assistance, car dealerships, fleet maintenance, and home garage use. Compatible with all standard 6V and 12V lead-acid batteries.
