I've been having trouble turning over my Street Bob lately and thought it time for a new battery. I bought a new HD battery from my local dealer. The sticker on it showed the battery had been put into service 2 weeks earlier (first charged?). Since the voltage measured 12.05 volts I decided to top it up after installing the battery. I used my 12v 1A trickle charger (not battery tender). The output voltage, when not connected, on the leads of this charger measures almost exactly 12v. After a day on the charger the battery measured 14.88 volts. Is this normal? Is this a healthy charge or have I overcharged my new HD battery?
