🔋 2-Quart Capacity Heavy Duty Battery Filler with Auto Shut-Off and Drip-Free Valve - Fast, Extra Safe, and Mess-Free for Golf Carts and Automotive Tools Review

The first one had a problem but the seller immediately sent a replacement which works as expected. Wouldn't hesitate to buy another one in the future if I need it. You must respect a seller who stands behind their products.

The theory behind this tool is that you can fill any battery cell without overflowing. Not this case! For some reason, air can flow around the spout, allowing water to continue flowing into the cell, causing an overflow situation. I would not buy from this seller.

Water ran out of the spout without getting into the battery. As a result, it was necessary to pour directly into the cell, which defeated the entire goal of getting a "reliable” product. Should have listened to previous reviews saying there were issues.

it fills slowly and requires good pressure by pressing the battery opening. It doesn't stop on its own when the water level rises, so you can overfill it if you don't keep stopping and checking the water level in the battery as it fills up.

I've tried contacting product support to see if there's a way to get this item to work, but no product support is available for this item. Each time I push the vial into the battery compartment, only a few drops come out. I've been trying to fill huge batteries for a solar system that powers a large building and each cell often requires a liter of water a month. A few drops at a time? Useless!

It's well made and works but bigger than I thought would like less. and with overfilling the battery did not go out, maybe it just wasn't glued properly, but I bought another one there, several seller names on these bottles are all similar. I replaced it with one that didn't have top fill, but that had nothing to do with the nozzle falling apart.

Don't forget to wear rubber gloves. You can't help but get battery acid on the spout of this picture for refilling water. You can burn your hands if you touch the spout and they get wet after topping up the battery. Charge the battery every three months to keep the acid level at the correct level when maintenance is not required. Replace the battery before the end of its life. There's nothing worse than being stuck with a dead battery.
