1.5v (vs1.2v) rechargeable batteries

[boss driver]

I see them on Ebay and other sites. Has anybody tried them?

A good set of rechargeable batteries are 1.4V when charged.. Lacross BC7000 and a set of PowerEX 2700s has been working well. Having a good smart charger that will allow you to run a refresh on the batteries and verify each cell can provide the rated output is very important.. one bad apple spoils the bunch. Also lets you run a break-in on the new cells so when you use them they last to the fullest capacity.
Do some research..

NiMH batteries are 1.2 volts/cell. You can charge then higher, but it's only a "surface" charge, and quickly drops to the 1.2 volts under load. If you don't believe me, put the freshly charged batteries in the unit, and run it for 10 minutes, and then recheck the battery voltage. NiCAD's are also 1.2 volts/cell. Lithium ion rechargeables are Nominally 3.6 volts/cell. They can be charged higher to about 4.2 volts/cell, but it causes reduced battery life.

Always been curious as to why the Nicads and Nimhs are only 1.2 volts. Can't they be designed with more capacity?

This explains the 1.5v NiZn rechargeable pros/cons as well as lots of other things..

MD need about 8.5 -9 volts so 1.2 is plenty as long as they they have a high storage capacity 2500-2700Mah

That's true for some detectors, but not all....some work best at the highest voltage.

It's simply a matter of the chemistry. Alkalines use a different chemistry than LI, or NiMH. It sure would be nice if they all produced the same voltage, wouldn't it?
