Autometer Handheld SLA Battery Tester

AutoMeter is well-known for making reliable, accurate gauges and test equipment for automotive applications. This handheld SLA Battery Tester, the RC-300, is a prime example of their commitment to providing professional-grade tools for mechanics and serious DIYers. If you're working with Sealed Lead Acid (SLA) batteries, whether they're flooded, gel cell, or AGM types, this tester will help you quickly and accurately assess their condition. It's designed to give you clear, actionable results, so you know exactly what you're dealing with, even with deeply discharged batteries.

What sets the RC-300 apart is its user-friendly interface and advanced testing capabilities. It guides you through each step, and the results are displayed on a clear LCD screen. You'll get detailed information including the battery's measured amp-hour capacity, current voltage, percentage of charge, and its overall state of health – whether it's good, nearing the end of its life, or simply bad. The tester applies a true 40-amp load, mimicking real-world operating conditions for more precise readings than simpler testers. Plus, you can 'blue print' known good batteries of various types and sizes, storing up to 40 different profiles to further improve testing accuracy over time.

This unit is built to last, featuring a tough, impact-resistant plastic housing with a rubber boot for added protection against drops and damage. It stores the last 50 tests in its memory, and you can even review or print these results using optional external printers or a PC cable, which is great for customer communication or record-keeping. The RC-300 can test both 6-volt and 12-volt batteries with amp-hour ratings from 4AH up to 50AH, and you can even set customized pass/fail parameters to match your specific needs.
