I wonder how big it is to physically deliver (only) 1.25 V at a capacity of 110 mAh. This won’t be powering much of anything in the near term. Also I’d be curious, as they claim it being water and organic matter based, if we could just “drain” the existing battery quickly and load in new pre-charged fluid to quickly recharge (I.e. recharge an EV as quickly as a gasoline based vehicle).
