Battery life (P15 Li-Ion):
The battery is maintenance-free.
A "P15" battery is usually designed for around 2000 to 4000 charging cycles.
A "P15" battery is usually designed for a service life of 2-4 years.
A "P15" battery should be replaced every 5 years at the latest!
The manufacturer's guarantee for new "P15" batteries is 6 months.
The battery capacity decreases with increasing service life.
If the indicated battery capacity is approximately 1000 mAh or less, the battery is probably weak and needs to be replaced.

Battery voltages "V" (P15 Li-Ion):
0.0 - 10.0 volts = battery defective - Dispose of - Must NOT be charged any more!
10.1 - 15.0 volts = deep discharge - the battery has probably already been damaged
It is NO longer possible to charge the Automower® (charging station).
(You can try to charge the removed battery with a suitable special charger. However, not recommended. Without guarantee.)
15.0 - 17 volts = empty battery. Should be charged with the Automower® in the charging station.
18 volts = empty battery. Should be charged with the Automower® in the charging station.
21 volts = fully charged battery.
Note Volt (voltage) has no influence on the battery capacity (power)

Battery current "A" "mA" (P15 Li-Ion):
Charging processes are primarily controlled by the transformer (not by the charging station circuit board).
The theoretical charging current for Automower®® 310, 315 and Gardena R100, R130, R160 is 1.5 A.
When the battery voltage approaches the nominal voltage of 21.0 V, the physical properties of the battery cause the charging current to decrease. If the charging current has dropped to 0.3 A, the mower is considered fully charged and the charging process is canceled.
The (measurable) (normal charging current) shown in the display is the nominal charging current for Automower®® 310, 315 and Gardena R100, R130, R160, 1.3Ah (1000mA - 1400mA)

Battery capacity "Ah" "mAh" (P15 Li-Ion):
Label on battery 18V / 2.1Ah (2100mA)
The battery is considered fully charged when it has reached 80% of its total capacity. Charging the battery to 100% would take too long due to the low charging current. Therefore, it makes most sense to stop charging a Li-ion battery at 80%. The maximum used capacity is 1.7 Ah (1700mA) - and not 2.1 Ah (2100mA) of the total capacity of the battery. (Label on battery 2.1Ah)

When the charge level of the battery has dropped to 1,000 mAh or the battery voltage has dropped to 17.5 volts, the robotic lawnmower switches off the blade motor and searches for the charging station.
