Brand:   Yuasa...
Voltage:   12V
Capacity:   20 mAh HelpAmpHour 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

Please read the following notes before ordering:
  • If you order this battery without the acid to go with it we will not be able to guarantee the battery. This is because we are unable to verify the specification or quality of the acid that you use to fill it and it would not be possible for us to confirm that a subsequent battery problem had been caused by a fault in the battery.

  • For personal callers we also offer a battery filling service at our shop in Enfield, North London, where you can buy the battery and have it filled with acid FREE while you wait.

  • Please note that shipping battery acid by air or sea freight is prohibited so we can only accept orders for these products for delivery to certain areas. In general these are mainland addresses in the UK, France, Germany, Italy, Belgium, Spain, Finland, Denmark, Holland, Luxembourg, Austria and Greece. If you are unsure if your delivery address will be accepted please contact us before ordering.
