If a detector specifies Alkaline batteries will regular batteries do any damage to the machine?
So far I have stuck to alkaline 9V, but wonder if the cheaper batteries will work just as well, but not last as long.

nope will not hurt anything, they will just wear out quicker.
The SMART thing to do is buy rechargeable batteries. Best thing I ever purchased for my detector. Bought two sets, one to have in my machine and one back up to always have with me. I have not bought normal batteries in over a year now. They have paid for themselves over and over again
I just bought rechargeable 9volts for my pinpointer too. 2 -9V batteries and charger cost me $16 on amazon.com
a regular 9V battery is $3-4 bucks easy, so you can see how it will pay for it self very quickly

Hi deepfoot,  
I agree with Goes4ever.   
We found the alkalines were getting far too expensive,  
and made the change to re-chargeables.     
Loved them so much and saved a bomb,
we've changed everything to re-chargeables.  
Just one thing to remember about re-chargeables,
for longest life and best performance use NiMH with AA size
don't use ones that are less than 2500mAh.
They will give more huntin' time.
We got heavy duty rechargeables for our pro-pointers too,
but the ratings are different for 9V block / PP3 NiMH 280mAh.
Hope this helps ya somewhat.
Ian n Eileen.

The biggest problem with the rechargeables is that the nominal voltage is lower. So they can appear like dead batteries to circuits that are expecting the higher voltages. These days, most manufacturers are building their circuits to handle these voltage differences. But some of the older equipment doesn't work so well with rechargeables. Basically, you just have to test it to see.
I buy my batteries at Harbor Freight when they go on sale. When they are on sale their 9V alkalines are 4 for 4.99 which is an excellent deal. And they seem to last for quite a while in my equipment. They also have the regular duty batteries for even cheaper but the alkalines are priced so well that I just use those instead. If I remember correctly, I picked up 24 AA alkalines on sale at HF for $4.99 too which is the best price around.
I also use the NiMH rechargeables when possible (Wii controllers, etc.). They really are fantastic for those kinds of high drain devices.

I found the best AA batteries are from Panasonic ultra hyper. When used in a whites they give me more voltage then regulars or whites rechargeable. So far I havn't run a set down to know how long they will last.

From the land of the Bluenose.....i tend to stay away from rechargeables as they get false memories and do not get a full charge. If they work for you by all means go for it!
