Battery type, charger technology, equipment loads, cable size, climate, and other factors can all vary. When a battery goes bad, it cant reach full voltage. Always use a voltage-regulated charger, with voltage limits set as described below. A battery dwelling above 30C (86F) is considered elevated temperature and for most Li-ion a voltage above 4.10V/cell is deemed as high voltage.Exposing the battery to high temperature and dwelling in a full state-of-charge for an extended time can be more stressful This is normal and you need to go have some lunch for an hour while the battery stabilizes. A fully charged 12V battery or battery-pack will read 12.7V or above; once that reaches 12V or below, that power unit is considered dead. The point is the value in the above table. Keep sparks or flames away from a charging battery. Cliff. Generally yes. The normal charging voltage range is 13.9 to 15.1 volts at 25 deg C, but below 0 deg C the charging voltage might be 14.9 to 15.8 volts. If there is another battery in the system that is good (at a higher voltage), it will charge the bad battery. The designer can select both the maximum charge current and the current threshold to terminate charging during the constant-voltage phase via an I 2 C host. So I am not sure how it will ever get to 14.6 unless I set one of those stages to 14.6. Generally, the battery is charged with high current and relatively high voltage when the battery voltage is low. The point is the value in the above table.
