Hello, Does anyone know of a cheap, quick way to check the remainder of AH left in a battery? I have a opportunity to purchase some used deep cycle 12 v batts from tornado alarm systems, they change them yearly due to the importance of the warning system working. They are at a mans business but I don't think he will allow me to do a load/time discharge test, but will allow me to check them and choose the ones I want. Any help/recommendations is greatly appreaciated.

There is no way to do it without a full discharge capacity test and that really takes special equipment. Additionally I would bet the batteries are Gel which is not what you want if you plan on cycle service with Solar.MSEE, PE -
probably get much the same info from the same people you did last time you asked this question.
