Motorcycle Battery Voltage Too High

The 16v you describe is definitely too high for charging a 12v battery 14 4 volts is a suggested maximum.

Motorcycle battery voltage too high.

We call this the open cell. The only other battery i ve used for my bike was a regular lead acid battery. Either way high or low charging voltage can lead to battery problems. Gassing is bad for the battery and also potentially for you as the gasses are explosive.

If you see something like that right after you charge your battery when re testing you might want to turn the headlights on for 30 seconds or so and re test because batteries can keep a superficial surface charge revzilla photo. If the voltage instantly drops to 0 volts that is also a problem. Battery voltage too high. Measure the battery voltage while the engine is running.

If the battery begins to hold and then steadily drops in voltage there is a problem. This is a common failure because of the way motorcycle alternators work. In order to get maximum battery life proper charging voltage must be maintained. I just recently got a new agm battery for my bike this one.

Yes a bad regulator will cause your motorcycle battery to be overcharged. With a voltage between 12 and 15 8 volts dc. The battery is a little pickier below 13 8 the battery will not fully charge. A healthy 12 volt motorcycle battery should maintain a range from 9 5 10 5 volts under the load for a good 30 seconds straight.

Can t do better than that. You don t say whether this is on the bike or on mains charge. It should be between 12v and maybe 14 8v max. That voltage seems a mite high.
