Pour with a screwdriver or...?
Everybody keeps mentioning to use a turkey baster to put water in the batteries and while this seems like a logical way to go, in fact, that is what I used to do, the problem I had was the hole in the baster was too large and the water would run out really easy. The hydrometer sold in autoparts stores (don't need a marine hydrometer!) that is used for checking specific gravity has a smaller hole than the baster and works a lot better. But, what I found that works really well is to just use a long screwdriver, or something like that, and put the shaft near the handle against the spout of the water jug (1-gal jug) and the other end above the hole for the battery cell and the water will just run down the shaft of the screwdriver. Works really well.Also, a plug for Bonnie's idea with the baking soda container. That's what I do too. Just a small plastic container with a snap top and I keep it right there in the battery compartment so there is no need to go looking for the baking soda when there is a problem. Because the soda is so convenient I often make a solution and do a quick wipe-down the battery tops, inside of the battery case, cables, etc. just as a routine to keep it all clean and free of acid.If the hydrometer is used by dipping in the battery acid the tip should also be cleaned or, what I do, place the tip in a container to keep it from touching anything.That acid can really ruin a pair of pants or a good shirt. Anybody know why they call it a "pair" of pants when there is only one of them (it)?
