Had a battery that I charged 6/7 times yet in the morning no start. Took to Altra 3 times and each time was told it was just undercharged. Tried 3 different chargers at different amperage with same result in the morning. Took to competitor where they told me battery was no good with a shorted cell and replaced. I question whether tests would be the same on a battery with no warranty? As a licensed heavy equipment tech I feel I have a pretty good grasp on how batteries are to perform. Too bad been dealing with them for years with great service. read more
