What type battery do you use?

I read my manual and think that Garrett recommends Ni-Cad for the ATP. I've been using rechargables that are rated at 1.2 volts. I recently found some 1.5 Super Alkalines and was wondering if they may kick up my power a little. Are they compatiable and do you think sending 6 volts to the coil as opposed to 4.8 would make any difference?

Someone posted an answer from Garrett about that on here, recently. It's below your post, called"lithium and o- rings. It contains a message from Garret about voltage of batteries.

There is a voltage regulator in the electronics which keeps the machine running at a lower voltage until the batteries are nearly exhausted. You won't get any difference with performance going 6 volts over the 4.8 volts.

My Sanyo Eneloops are rated 1.2v, but they always test at 1.4v after charging. They've done a great job for me over the past year.

I've used numerous different brands of alkaline batteries and the Energizer Lithium's. The lithium's lasted longer, but not enough to justify the expense. They work well in my camera though. I stay away, from experience, from Harbor Freight and Rayovac alkaline. They don't last as long as Duracell and Energizer, and several store brands, like Radio Shack, Walgreen's, and Kroger. AS for rechargeable. Look for the highest mAh rating you can find. I'd stay away from ebay purchased, if not name brand, or at least something others have heard of. Bought some 2700 and 3000 mAh and they didn't even hold a charge. Duracell carries a 2600 mAh, but all I can find in store are 2450 mAh. Harbor Freight rechargeable have worked well for me, the higher mAh, but aren't much cheaper than name brands. None of the rechargeable I have used will last as long as an alkaline, but you can simply carry 2 or 3 sets and recharge after each use.

Good Luck!

I have several types of re-chargable batteries, but nothing lasts as long as the 99 cent store alkaline batteries. I have gotten as much
as 40 hours on a set. They weren't done yet, but I was going out of town and didn't want to chance them. Most of the energizer re-chargables
last half that long at best.

I have documented the 99 cent alkaline batteries versus the top brand non rechargables and the chepo's last way longer. Why I do not know.

Good luck and Happy Hunting.

For alkalines I've used sonys they don't last long. But been using sunbeam alkalines and man they last
