Using A Pro-find 35 Without A 9v Battery

I like the nostalgic 9v's. Just ordered some rechargeable lithium aa batteries that are 1.5v for my Tesoro as it eats up aa's pretty quickly. Found some on amazon for $20 for 4 with micro usb cable to recharge them. Will let you know how they work out. Regular AA's drop performance too much when they are about half way dead, hopefully these will be much better.

Wonder if they have a lithium rechargeable 9v out there?

EBL 9V batteries are some of the best, and have been tested against other rechargeables. They consistently output very close to their rated capacity vs others. They aren't outrageously priced either.

These are the ones I have, along with the charger.

A test here, with teardown.

Those batteries look great. Does that 9 volt have enough power for the Garrett carrot? In other words is the voltage high enough to not have the pin pointer trigger a low battery warning?

No problem getting 2 full  days in the tesoros and 3-4 in the carrot.  

On the fisher f-pulse, the batteries last several month (!!) with plenty of use, light + vibration enabled....
