    9v Rechargeable Batteries & Charger?

    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?

    Many thanks.

    How often do you expect to replace the batteries? I mention because rechargable batteries have a high self discharge and go flat in about a month, used or not.
    I just stopped our site manager buying them for clocks and remotes.

    You can get stay charged rechargeables now, I use them and they are much better.

    Something like this may be of use to you: http://www.amazon.co.uk/UNIROSS-Seri.../dp/B009M78L9E

    Thanks for this. Our equipment vendor says it's okay to use rechargeables and that they should be okay for a couple of months which is what we want.
