Gpx 5000 battery

Question. My mate has a GPX5000 with the original 6year old battery. He won't buy a replacement battery or spare until the other one dies.

Will the battery die suddenly and ruin the trip, or give an indication it's on it's last legs? cheers Pete.

One of the original batteries for my 45 was on its last legs, wasn’t holding charge,going flat after a couple of hours,but it’s like anything could go for many more years or give up tomorrow,extended trips always take a second battery and lead,nothing worse than your battery going flat digging a hole or arriving at your destination only to find out your lead is stuffed,had both happen

I'm hearing you mate. A problem with a detector can ruin a trip. cheers Pete.

been there done that ,spare battery and leads essential for one's sanity
