Rated 3.6 out of 5 by 11 reviewers.
Rated 1.0 out of 5.0 by Can still overfill battery I bought the filler bottle so I wouldn't have to worry about overfilling the battery cells and so all the cell levels would be correct and the same. The bottle does not provide a tight seal around the battery fill hole therefore you can still overfill the battery. It seems like it should have a soft rubber washer to provide a good seal instead of hard plastic. February 19, 2015
Rated 4.0 out of 5.0 by This is a good product. Works as advertised with no problems. A bit pricey for a plastic bottle with 1940's technology. September 8, 2013
Rated 1.0 out of 5.0 by Didn't work - overfilled battery I returned this item because it didn't work at all as advertised. To work properly, this bottle must be air tight, but it leaked air around the telescoping nozzle which actually caused the bottle to overfill the battery. February 11, 2014
Rated 5.0 out of 5.0 by So much easier, less spillage than trying to just pour it in, glad I bought it Very usefull for refilling my battery, quick and easy September 5, 2013
Rated 5.0 out of 5.0 by Works Great!! Don't have to take battery out of its case now, just remove caps and fills automatically with this filler. August 21, 2013
Rated 5.0 out of 5.0 by This is just an outstanding product. This product fills each battery cell exactly, without worry you may over or under fill each one. It is so easy and quick to operate and no more messy wet battery tops. It was simple to order on-line and pick-up at the store two working days later - that is quick and professional service and shipping. May 13, 2014
Rated 1.0 out of 5.0 by Worked but broke Worked as advertised but the filler nozzle broke after the first use and I can't find anyplace that just sells that part. April 10, 2014
Rated 4.0 out of 5.0 Battery filler bottle With the spring loaded filler neck, this bottle will easily make adding distileed water to any battery an easy task August 14, 2013
