Brand:   Yuasa
Voltage:   12V
Capacity:   17AhHelpAmpHour or Ah measures the capacity of a battery.
In simple terms, the higher the Ah the more energy the battery can store.

If you imagine a bucket of water, the bigger the bucket, the more water it can store.

For example.
A 20Ah battery can normally deliver 1 Amp for 20 hours or 2 Amps for 10 hours. At extremes the performance usually drops, for example it may not deliver 20 Amps for one hour.

1Ah = 1000mAh
CCA (EN):   270A HelpCCA or Cold Cranking Amps, measures the starting performance of the battery.
In simple terms, the higher the CCA the easier it will start the engine.

DIN German Industrial Standard at -18C
