Alkalines or rechargeables ??

Wondered if there is any performance difference in using alkalines as opposed to rechargeables for the MXT? I have both and notice that new alkalines always show as 12 volts initially while rechargeables are never more than 9 volts. Does this affect performance or not? I Put freshly charged NiMh rechargeables in my machine the other day when my alkalines ran low (9 volts) and the machine just did not seem happy at all (loads of disappearing signals etc) !!
Any preference or opinions anyone ??
 
My past experience with recharable batteries, in various equipments, is as follows: Rechargeables can be very difficult to deal with after they've been charged a few times. They will build up a memory voltage in them if they are not totally discharged and then recharged after about every third charging session. So if you used your detector and came home and the state of charge was reading nine volts, for instance, it would not deep cycle charge, and get the full amphere rating from the battery. This would shorten the usage time considerably. My suggestion is to get a 12volt bulb and attach two wires and attach them to your battery contacts to fully discharge/drain it before re-charging. As re-chargable batteries age they must be eventually replaced with new ones. (My opinion for what it's worth.)
 
We use them in our MXT and have no problem with them other when they get to a certian point they will die quickly. I Use the Nickle hydride as they built up no memeory like the nicads do.
Being I use a Explorer most of the time I have a couple of Explorer pack with me I built using 8 Nickle hydrides, so if the wifes MXT battery gets low I just have to change the batteries from one pack to the other and when I get home I use my Sunray charger to recharge them in the Explorer battery holder.
If you are going to use Rechargeable, it would be nice to get a charger that will also discharge to a safe leval and then recharge to the correct level, then go to a trickle charge in case you forget them on the charger and over charge them.
We like the rechargeables and see no performance differnt in the alkilines or rechargeables. The detector has a voltage reg built in to it so wheither you have the 12 volt or 10 volts the detector regulated to only using maybe 8 volts of it as I beleive I have heard of some MXT going to as low as 8 volts before it will not operate.

I bought from WALLMART a brand of NiMh that were 2150 ma--They have worked great for me--For $20 you get 8 batteries and a charger (I think thats right)Take a look at their Digital Brand---In PHOTO Dept---DeathWind1
