Alarm siren battery help

Hi guys my ring alarm is coming tomorrow and I’ve just seen you don’t get the quick release battery with the siren is this needed along side the 3 D battery’s if so what is the pros to buying the quick release battery and fitting it along side the other battery’s?

Hi @Darrenm84. You do not need to add the quick release battery for it to work; the Outdoor Siren will work with just the 3 D batteries. The quick-release battery is rechargeable and can be used with a Ring Solar Panel to trickle charge it. We have this Help Center article that explains the different power configurations for the Outdoor Siren, which is only available in the UK.
