Brand:   Yuasa
Voltage:   12V
Capacity:   11AhHelpAmpHour 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
