So I picked up another GB2, I think my 3rd. After a 10 year stint in the West TX oilpatch I am back to prospecting. I got the GB2 again for picking out dinks while i drywash. 

I found an old 2015 post from Steve stating that these worked.

Looking for info on what's recommended now in a rechargeable 9v for GB2

Thanks

I've been using these Powerex ones for years with good success.

The Powerex Precharged MHR9VP Rechargeable NiMH Battery (9.6V, 230mAh) is a nickel-metal hydride battery compatible with Powerex's MH-C1090F 10-Bank Charger or MH-C490F Stealth Charger. It is rated at a voltage of 9.6V and a capacity of 230mAh, with a minimum capacity of 215mAh. It has the ability to outperform a standard 9V battery due to its slightly higher voltage. The battery is capable of being stored for an extended period of time and still retaining a full or nearly full charge. After a year, for instance, it will retain 85% of its capacity. The battery comes pre-charged. The purchase of an NiMH battery like this one saves you money, since you won't need to buy endless supplies of non-rechargeable alkaline batteries.

Pre-charged and ready to use out-of-package

Can be stored for extended period of time without substantial loss of power

Retains up to 85% of charge after one year of storage

  • The title was changed to New Model Gold Bug 2 Rechargeable Batteries

I have been using these two in some detectors and they have been working very good, I have no experience with

the Gold Bug 2 though so not sure how they would work with the GB2
