EZRED SP101 Battery Hydrometer, Factory

I use this to check SG off a forklift battery that I'm using in my off-grid solar system. It seems to be working and SG tracks voltage as expected. It's easy to use and does the job. I didn't know how accurate it is as I didn't have anything to compare it to. I have a couple of criticisms, I wish it had numbers marked between fair and good so I don't have to estimate, and I see small cracking around the edges which I know can come from the method used to weld the 2 halves together or if solvent is used to clean it in the manufacturing process, but to be fair, I have also left this under the metal cover of my battery outside, so it has been exposed to the elements and temperature swings below freezing. So far no leaks but even if the long term durability isn't there, it's cheap enough to just buy another one.

Does EXACTLY what it’s supposed to do! As forklift mechanic we’re contacting acid levels in our electric forklift batteries and this gets the job done quick and efficiently!

Seems to work well… But can anyone tell me where the “Fahrenheit & Celsius scales” are located? 🤣

Worked well for monitoring/bringing back 6v batteries on my lift. Batteries were charging for 3days while I monitored the PH with this tool and was able to see it increasing daily vs assuming if batteries were improving. Let's you know if they'll hold a charge or if you're wasting your time charging. Use only "distilled" water if refurbishing/filling

Works very well. Excellent build quality. Ease of use and design is good. Able to use as a transfer from one cell to another. I squeeze the top slowly to absorb the material into unit. Extremely sensitive readings with this product which worked great for me. Do not breathe the fumes so this works very well in doing that. Be safe. Wash it up and put unit back into the package it came in. Awesome. Thanks

I'm so glad I spent the extra few bucks to get this battery tester over the basic ones. It's high quality, Made in USA. It has the specific gravity numbers, which I was looking for, as this gives you more information to work with. It does have the "Low, Fair, Good" indicators too, but having specific numbers just provides you with a better understanding on the health of your battery. The indicators are also PRINTED on the plastic, instead of a sticker that over time gets peeled off from acid or just regular use and then you're stuck with a uselesss piece of plastic. Big plus! I actually read the directions for once and washed it out with soapy water and multiple clear water rinses afterwards. I want to take care of this since it's well made. I'd recommend this!

I am not one to get excited about hydrometers but this is a very nice one and is easy to read and use. Hold it level to get repeated accurate measurements but you just need to tell if it makes it into the 'Good' section. I also have an old K-Mart floating-ball type which has 4 different colored balls that all float to the top if the cell is OK. It checks the specific gravity of the charged liquid-acid only; it will not tell you if a cell is shorted, nor can it stress-test the battery. I recommend adding only distilled-water, yearly, up to the lower part of the hole, leaving 1/2" to 1" below the top (be sure the metal plates are covered well), trickle-charge at no more than 2 amps with a charge that tapers-off as it reaches full charge then maintains it, then check the specific gravity of each cell. If your battery is old, or has any problems, get it tested free at your auto shop or a vehicle battery place. If there is any question, replace it, before you get stranded. I had a battery go bad in the parking lot of a Costco, luckily; it was 12 years old and suddenly died. If you use an additive, 'Battery Equaliser' is the only one mentioned that seems to really help, but when a battery is not working well, replace it. Stranded is miserable and costly. Do not expect it to work beyond its stated month. Be pro-active with this important car-starter that can go bad in summer heat and winter cold. Ever been stranded with a dead cell phone battery? Not good. This is for checking a youthful battery yearly. I just had an 84 month battery go bad at 30 months and it was replaced for free. This helped me get it replaced. Hope this helps you.

The hydrometer is small so the volume of electrolyte that must be drawn is small. This is important for small batteries such as the one in the Honda CRV. The device can be easily leveled by just sighting the water surface and comparing to a line near the top of the device. The pointer is small, and the markings on the surface are precise. I did discover some problems at about 3 years, and removed two stars due to these problems. 1. The case develops some severe radial stress cracks, eventually leaking. 2. The markings began transferring from the hydrometer to the plastic bag, making reading difficult. I rinse the device and store it in the bag in which it was originally packaged, 3. There seems to be a compatibility issue between the plastic and the rubber tube, as the plastic softened where the tube contacted it. I now remove the rubber tube for storage, but it will still glue itself to the plastic if ittouches.

An sich ein gutes Produkt. Es ist gut ablesbar, für meine Zwecke musste ich den Schlauch abändern. Das Gehäuse war jedoch an der Klebung der Gehäusehälften undicht. Das bedeutet, es zieht beim Einsaugen der Säure Luft. Eventuell durch den Transport verursacht, da nur in einer Papiertüte verschickt. Ich hätte das am liebsten reklamiert, aber durch die lange Lieferzeit habe ich mir die Mühe gespart und stattdessen das Gehäuse geklebt. Funktioniert jetzt wie es soll. Entweder besser verarbeiten oder besser verpacken wäre sinnvoll.

Very good tester used that style in the shop for years

جيد

Fast delivery, compact and functions well.

Excelente equipo para saber la vida útil de tu batería.
