9v Rechargeable Batteries & Charger?

[tech_guy]

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.

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.

Thanks for this - I will purchase some and compare them with Duracells.
