I need to purchase a lot of 9v batteries for use in motion sensing equipment. Alkaline 9v Duracells are expensive at £3.50 a go. I was thinking of using rechargeable, such as these:
RS Components Duracell 9v Rechargeable Batteries
With this charger:
RS Components Duracell Battery Charger
Does anyone have any experience of using these / any other recommendations?
