4500 batterys how log do thay last


Recommended Posts

I am pretty sure my batteries are original one that came with the 4500 I purchased from a friend. So lets say they are about 6-7 years old....I have two and alternate them..between charges,,,,one battery may last me 5-6 hours than it gets a bit noisey cause of the voltage drop....I would like to buy a good used one just in case....one of the two go bad...

Hey Hobby,

All the guys information prior is correct. The GPX batteries when they are new are able to get 14-16 hours out of them. I have hunted an entire weekend on a new stock GPX battery. As you charge them and they age, the life will drop some. If you're getting 8 hours out of any older battery, say a few years old, then it's ok.

Hey Hobby,

The regulators on the older GP series were onboard. I would have to ask the Minelab Engineers if it's now in the GPX batteries or onboard like before. The stock batteries are bullet-proof, but many, like myself, hate the harness and power cord hanging off. I love the Goldscreamer Power Pack for the GPX series though. It's a bit pricey, but well worth every penny in my opinion.
