I purchased a Zapino in mid August 2007.
My commute to work is 4km; after 1159km, I can no longer make it to work on one charge. I charge the batteries after every ride (at work, and then again at home).
I measured the voltage of all batteries 4 hours after a full charge as follows:
After full charge:
4 batteries are at ~13.7V, one battery is at ~13.2V.
I am certainly disappointed in the battery performance of my scooter.
How can I fix the situation?
I emailed Zapino, and they offered to sell me replacement batteries at $99. They seem unwilling to cover the batteries under warranty.
Would replacing the single low battery fix the problem?
I actually posted about the battery problem as early as Fri, 09/14/2007.
At that point, the voltages were 13.3 and 13.1.
I live in Virginia.
I was thinking about buying a fancy de-sulphation charger like the BatteryMinder here
Would that help?
Thanks for your help.
