Why would I want to buy this gadget compared to investing my money in rechargeable batteries? I would probably use non-rechargeables for smoke detectors only.

Why would I want to buy this gadget compared to investing my money in rechargeable batteries? I would probably use non-rechargeables for smoke detectors only. Also the environmental impact is less with rechargeable batteries[1] [1] http://ec.europa.eu/environment/waste/batteries/pdf/battery_report_june2010.pdf http://ec.europa.eu/environment/waste/batteries/pdf/battery_...

If this actually works as promised, it would help with the environmental impact of disposable batteries by greatly extending their life.

  Quote from the study linked in grandparent: NiMH batteries compared to alkaline batteries cause about 96 times less damage to each of the three damage criteria (for 400 cycles). So even if batteriser allows alkalines to be used 8 times longer, rechargeable (NiMH) batteries would still be 12 times better than that for these three criterias (human health, ecosystem quality and resources).
