It does not mean that, what was explained to me by a GNB/Exide Tech guy is that continually opportunity charging can led to issues that result in customer dissatisfaction. I would suggest you talk to your local rep for more in site.

What batterty experts have always told me, including cell phone batteries, a battery has so many charge cycles, like 1400 - 1600 range. And every time you hook up to the charger even for a short period it counts for 1 cycle.
