NEIKO 40510A Car Battery Tester | 100 AMP 6 and 12 Volt Automotive Load Checker | CCA Analyzer

Works as stated. I have two of them, one at lake , one at home. Great way to check on the viability of car/ boat batteries. Worth every penny!

Make sure you read the book it says it'll get hot enough to burn you and cause property damage that it can it says it will get hot enough and will burn you. It worked a couple seconds used it to test one battery. As soon as you hook up the cables instantly goes to where it should be so you can unhook it then if that's all you wanted to do then with the load tester you know hook up the cables and instantly reads and then hit the load tester maybe two seconds and it goes right to where it should there's no need to run it any longer than 2 seconds then unhook it. Used it a few I like it. It does get warm fast probably hot like booklet says if you hold the load tester mire than a few seconds. It did smoke till the 5th use now no smoke. Cheap price no big name brand but it works great.

I decided to get a battery tester to keep up with all the various 12 volt batteries we use on our farm. I didn't want to spend 50 bucks for the name brand so looked at all the different knockoffs and settled with this Neiko. I can now say I made the right choice! I have tested it on about a different different batteries and it does exactly what it was designed to do. It shows how much voltage sag happens when batteries get put under a load. It clearly showed me which batteries are getting weak and which ones were still strong. The tester is well built and well designed. It should last for years. Nice when something is cheap and works good. This one is a winner!

Cheap and works for what I need it to. Mostly testing 6v deep cycle batteries for electrical pallet jacks. If you want accurate voltage readings, you'll need to use a multimeter as well, the analog dial isn't very easy to get exact numbers from. Haven't tested on a 12v. On a 6v it pretty consistently draws 48-50 amps, which is true to its 100amp rating at 12v

This is great for checking your battery voltage, as well as alternator working. Shouldd read 13 volts or more when alternator and motor is running.

works great

Doesn't get better than these old school manual style tools, no electronics just straight information that you can trust

Saw another review claiming this tester only draws about 60/100 amps, and I wanted to test this to see if they were right. I used a DC amperage clamp meter to measure how many amps this tester actually draws. It starts at about 95 and slowly drops to about 90 as the resistance increases when the resister in the tester starts heating up. If I used a fresh battery that was 12.8 volts I’m sure it would read 100 amps, but the battery I used was maybe 12.5 volts. This is a great load tester for a great price, just don’t test multiple batteries back to back to back, it will ruin it. Let it cool down for 10-15 minutes between each test.

Excelente si tienes taller o eres hobbista

Great price for the job it does.

I didn't like it not accurate

good to have
