Clore Automotive Solar 1876 1000 Amp Carbon Pile Battery Load Tester, One Size, Factory

It is BIG. It is a different animal than people are used to. Carbon pile that is adjusted by pressure and released. Dial up to the current you want to test and hold for the test period then let off back to zero. Knob is spring loaded to zero. Will not hold position by itself, completely operator controlled. Some have mentioned the amount of turn before you start reading... was going to reduce that but decided it is best for safety to have the gap. Gap may be less for the different current models. High current testing is not done for long due to heat capacity. Does have large cooling fan to cool the Pile. Picture shows 24 volt in 5x pairs of 12volt deep cycle batteries.

I really like the unit, but I don't recommend it to the average consumer. I have decades of experience in electrical and I think the unit works great. I have tested the batteries in three vehicles so far. One of the vehicles was my neighbor's. His battery failed and I offered to charge his battery before he left my home. He said, "My alternator will do that". His alternator would've charged his battery back up IF he drove the vehicle a long enough distance, but he didn't. The next morning his vehicle would not start. So, if a battery FAILS, charge it up as the test itself puts a strain on the battery. My neighbor knew better than to complain about it because I offered to charge his battery. If you do purchase this tester and you're asked to test somebody else's battery, keep this in mind, especially if the battery FAILS.

I was a bit nervous about ordering this unit because of a few negative reviews. But, I decided to give it a chance as the specs were solid, and the positive responses far outweighed the negative ones. I already have a really nice Sun VAT-40, which is an excellent unit despite being nearly 40 years old. Those thing were built to last a few lifetimes. But, I wanted a smaller, more portable portable unit that could handle more than 500 amps for a load test, just because. I did a load test on a recently charged battery side by side with our Sun VAT-40. I found the amperage and voltage meters were plenty accurate, and the carbon pile was easily able to put a 500 amp load on the test battery. I rarely use the unit, but when I do I find it is a solid performer.

Item as described. Verry good packing and fast delivery

Will test any larger battery with a load test, the only way to test a battery.

Get the warranty, volt meter quit at about 1.5 years. Harbor Freight has same thing less money, better handle.

Not that hard to learn to use. You need to be somewhat knowledgeable about it's use. Read the directions f or sure.

It is heavy duty enough that I have tested 4, 950 cca batteries all within minuets of each other wirh out it overheating. So far so good.
