The AL 1830 CV is a smart charger from Bosch. With this charger you can supply all 14.4 V or 18 V batteries from the Power For All line with power and fully charge them in a short time.
The charger is smart, which means that it automatically selects the best charging current for the charge level of the connected battery, so that it is not only charged as quickly as possible, but also as safely as possible. A 1.5 Ah battery is charged in 33 minutes, a 2 Ah battery in 45 minutes, a 2.5 Ah battery in 60 minutes, a 3 Ah battery in 72 minutes, a 4 Ah battery in 95 minutes, a 5 Ah battery in 105 minutes, and a 6 Ah battery in 130 minutes.
In addition, the charger has LED indicators that indicate the charge status of the connected battery. The charger also gives a 'ready for use' signal when the battery charge status has reached 80%, so you can get started even if the battery is not yet fully charged.
