Is 14.8 V battery good?
In general terms - If the battery is 14.8 volts (and in the unlikely event it fits) it should be safe to use and will probably work OK, but not get fully charged (so less runtime).
Is 14.9 volts too high?
14.3 - 14.7 is normal but depends on how accurate your meter is but once you start pushing up to and over 15 then the system needs checking before damage is done.
Is 14.7 volts overcharging?
The multimeter should read between 14.2 and 14.7 volts. If the reading is higher than 14.7 volts, then the alternator is overcharging. Turn on the headlights and other electrical accessories. The multimeter reading should not change significantly.
Is 14 volts lethal?
In the US, OSHA (the Occupational Health and Safety Administration) considers voltages over 50 volts to be hazardous, and they do not distinguish between DC or AC or AC frequency. Can a 14v DC get someone electrocuted? Dry skin has a high resistance, and 14 V with a small contact area is not much of a threat.

So some batteries different, some car alternators regulate above 15.0 volt to suit the headlights, but 14.8 is high for extended running and is in a high gassing area, so you may not destroy the battery, you will be using lots of water. Also check for bad connections if it.
Is 14.2 volts good?
The voltage profile will depend on the specific battery, but for your typical iron phosphate batteries, the range is 14.4 ± 0.2V. In other words, you should monitor between 14.2V and 14.6V while the battery is actively charging. Anything less might just be a trickle charge, if it charges at all.
Is 14.8 volts too high AGM battery?
AGM batteries generally charge at 14.6-14.8V, not the 13.6 - 14.4 of standard lead acid. Charging at 14.4v will undercharge the battery- not a terrible thing but it has to have some kind of termination mechanism, you don't want to float charge it at 14.4v if its full.
Is 14.2 volts too high?
If you are referring to a standard lead acid car battery, nominally rated at 12v, these are actually 12.6v when fully charged, but need up to 14.4v (a little more in cold weather) to charge fully, so when they engine is running, 14v would be quite normal.

For example, a shock passing from one arm through the chest to the other arm is much more dangerous than a shock between two toes. Here's some examples: A static electricity shock can be 20,000 volts or more, but at extremely low current and for an extremely short duration: Harmless.
Is 20000 volts safe?
Your resistance is so high that 1 volt would only be able to push about 0.0001 amp of current through you, even if you're wet. 230 volts will not be able to push 1 amp through you, although it can push enough to kill you under the right circumstances. So, 1 volt is not dangerous and 230 volts is dangerous.
Is 1 volt safe?
Well 10,000 volts are really dangerous. However what matters is if the voltage is sustaining volts, or a quick discharge ( capacitive ) volts.
