ACT 612 Lead Acid Intelligent Battery Tester SLA, Gel and Flooded Batteries

When doing preventive maintenance, this tester will test voltage and amps as advertised.

works as described. I'd buy another one if i need.

I highly recommend this product and all the technicians I know use it. I wish it had a magnetic strap so you could hang it.

Works as expected.

I work for a major company, as a fire system technician. This was a small investment and could tend to scare potential customers away, but the reality is that it is an integral part of my job, a time saver and well worth the money. Within two minutes you can load test system batteries and accurately know if they can support a system in the event of a power outage.

The search for a battery tester capable for testing SLA batteries ended on this product. Searched lot of online & offline stores in Dubai but couldn't find anyone. The product is great as per the initial testing but dont know why the product cost this whopping 360 $. The product was purchased for testing SLA batteries up to 7 Ah used in Fire alarm & suppression panels.

Great meter. Does what it suppose to do. It does not require batteries. It gets energized when you test the battery.

I bought this for its load-reserve emulation, which is what I really need. I tested a small variety of charged and flat SLA, Gel, and flooded batteries. The first couple, the Ah estimate made sense (lower than labeled, old batteries), but subsequently the Ah reading was extremely variable, especially on new auto batteries at the auto-parts store, comparing their professional tester with this. I thought that perhaps I had a bad example, and asked Amazon to exchange, but that was not possible, so returned it. Now reviewing less expensive models.
