Mighty Max Battery Battery Filler Jug Type Includes Battery Hydrometer - Acid Tester, Electrolyte Density Checker

Very simple and quality built battery service jug. Shut off works perfect. Expect it should outlast all the batteries I will be servicing. Excellent value for the price.

I had purchased a different brand a long time ago and it leaked and never worked well. Was a little hesitant to purchase this one but I'm glad I did because this one works as advertised!

A little pricey for what you get, but it works. Except the one they sent me the bottom was crushed and creased. The box was perfect so someone packed one that appears to have been smashed. White creases in the dark colored plastic. Amazon was great in sending a replacement. If they comes through unscathed, I’ll bump this to a 4, maybe even a 5. The no drip spring loaded valve is great. Nozzle size perfect for my batteries. So much cheaper than the auto waterers. Update, new one is flawless and works wonderfully.

This is a great water filler for my golf car batteries. As long as the jug is more than half full it fills the batteries quickly. If it takes too long to fill then you need to do it more often. The batteries should be checked at least every 3-4 weeks and more often if used and charged a lot, especially in a hot environment. As long as the tank is full it fills quickly. I did six batteries in like 20 minutes. I had to fill it up twice. The level was perfect. No under or overfill. Shut off automatically. The shape is a little weird as sometimes it hits the battery/cables but I was able to get around that small limitation.

Worked for 3 months then the nozzle fell apart throwing a spring out and not doesn’t work. Second on for me to do this. I’m trying something different next time.

Don't waste your money! In Apr 2023 I purchased the Mighty Max battery filler which was dark blue in color, held 2 qts of water, stopped adding water when the correct level was reached and never leaked. The container body felt like a sturdy material and the nozzle was dull black felt strong and the internal gasket (water seal) was soft and strong. This replacement is also called the Mighty Max but is completely different. It is light blue in color, holds less water, "feels" cheaply made and leaks like a sieve where the spout screws onto the container. The nozzle is a gloss black plastic feeling cheaply made and even trying to use it will not automatically stop the water flow when the battery cell is full. Further inspection revealed the gasket inside the spout is made of hard what looks and feels like plastic material and no way will it form a water tight seal. Amazon offer numerous battery water fillers most of which look exactly alike some called Mighty Max and others with no name and prices that are mostly identical. Why my recent "replacement" was still called a Mighty Max but was nothing like the original is of prime concern. I am hesitant to order this again for fear of getting yet another of the exact same piece of junk

This works perfectly for filling the batteries with water for our golf cart. No fuss no mess. Correct amount gets in each battery every time. Highly recommend

Bf was very happy with it. Made his life easier.
