But the high
voltage of the
fully charged KERS
battery pack needs careful protection and handling.
If the
battery is at or below the empty
voltage (which for lead acid antimony
batteries is at 11.89 V, but the
battery can in theory be at any
voltage between 0V and 11.89 V and it is in any case approximately empty), and has 48 Ah capacity, a 1.25 A charger will
fully charge the
battery in approximately 38.4 hours (just divide the Ah of the
battery by the amperes of the charger), but I would add few hours more because the end of the charging occurs at constant
voltage, not at constant current.
Your 12v adapter would only be able to raise the
battery voltage to 12v, but to charge a car
battery fully you would need to raise the
voltage to 13.8 v.

fully charged
battery will give you around 12,8 V, when the engine is running it will be most likely around 14,4 V. Your device (if it is a compressor) may run «better» / «faster» with the slightly higher
voltage.
