SKB SKEV12-20, 12V 24Ah/20h, 12V 20Ah/2h lead-acid rechargeable cyclic (deep cycle) AGM battery. Dim.18,1x7,7xH.17cm

SKB SKEV12-20, AGM cyclic (deep cycle) rechargeable lead-acid battery 12V 24Ah/20h, 12V 20Ah/2h. Dim.18,1x7,7xH.17cm Term. M4.
Dimensions: 181 x 77 x 170 mm. Weight: 7 kg.
Standard charging current:  max. 1/4 of capacity
Charging voltage for cyclic use:  14.6 - 14.8 V
Applications: small electric traction: electric bicycles, scooters, apparatus for disabled people, stairlifts, golf  trolleys and all applications where daily charging and discharging is required. 
The SKB batteries for cyclic use in the SKEV series, thanks to the use of a special plate, are suitable for use in electric bicycles and equipment for the disabled, golf club trolleys, lifts etc.. Its discharge efficiency is given by the fact that it can perform approx. 600 cycles at 60% depth of discharge (8.0A continuous discharge) while discharged at 30% capacity it reaches 1,200 cycles. The service life of the battery is counted in number of cycles.
To ensure correct operation of the battery, certain requirements must be observed.
CHARGING: Charging must be carried out at constant voltage and strictly in accordance with the data on the battery. Incorrect voltage can lead to immediate deterioration of the battery. The battery must not be left uncharged after use, but must be recharged immediately.
DISCHARGE: during the discharge phase, the voltage must not be lower than 5.25 volts for a 6V battery, 10.50 volts for a 12V battery.
