Rated 3.8 out of 5 by 13 reviewers.
Rated 5.0 out of 5.0 by If you have a Watchdog battery, this is a must have Don't procrastinate on buying this item. When the battery needs to be topped off in the middle of the night, you don't want to fiddle with funnels and possible mess, not to mention the tricks with lighting you have to do to try to get each cell at the same fluid level. This makes it idiot proof and simple. It should honestly just come with their batteries in the packaging. May 24, 2016
Rated 5.0 out of 5.0 by Simple watch dog refill bottle I finally had the opportunity to use the prescribed watch dog battery water bottle. No mess no fuss. Previously this was a chore necessary but not fondly looked forard to. I would use a flash light to shine on the opposite side of the battery to show how much water was in each cell and then I would typically spill water attempting to fill the cells with distilled water. What a pain. This bottle makes the whole process of assuring the proper water level is attained and in a very timely manner. April 23, 2016
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 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 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 Just used it . Worked great. lightweight and easy to use Had bought a Watchdog battery, had markings on the outside to show fill to line. But to see the lines we had to lift the battery out of the case, very heavy . Knew there had to be a better way, store did not know of any. Found this on the"net". There was no mess,fast and easy. Don't know what other people do but this is the way to go. Surprised stores don't carry them October 1, 2012
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
