Water coming out of battery

The 13 volts dc is NOT adequate to recharge the battery. Why don’t you TEST the liquid. As noted by MrPhil? Baking soda and battery acid will fizz like an Alka-Seltzer. A white cloth will show green if the liquid is antifreeze If it’s another oily substance, you’d be able to tell that, too. You didn’t say whether the electrolyte in the battery is low, or not. Is it? Is the antifreeze, and other fluid levels (oils, etc.) where they should be? //// [One’s got to love this new feature of being able to edit after submitting a response.
