How does one know when battery pack is fully charged?

[Tony N (Michigan)]

I got my new Explorer SE Pro the other day. Instructions say to charge the batteries for 18 hours the first time you charge them.
I charged them overnight for 19+ hours but the red light stayed red on the charger this morning. Is this red light supposed to go off when the batteries are fully charged?
I put the pack in the Explorer this morning and it shows full charge on the detector icon.

That's it. Red light stays on. I guess you can't overcharge it. Enjoy your new machine. I've had an explorer II since it was released and just got a new etrac last week.

Just Google "leaving rechargeable batteries in charger" and read that batteries do suffer after sitting in the charger long after it full.

I agree but on page 23 of the Manuel says that minelab batteries can stay on the charger indefinitely. I charge overnight and unplug in the morning just to be safe.

I've thought about it myself but never did it. Seems it would work great?

Besides having the new and fantastic Lithium Ion battery pack that only take 2 hours to charge,
I have three Minelab NiMN battery packs. It just sucks that there is no way to know when one pack
reaches full charge to begin charging the next one.

Interesting that I took my new SE Pro detecting yesterday and after about an hour the battery icon
began to show some discharge. It's a new NiMH batter pack that
came with the detector. This is perfectly normal. I understand that.
It's no diss on Minelab. I've put over 6 hours on the Lithium pack and the icon hasn't moved yet.
