Is the WM-10 battery a Lit-ion or NiMH ????

[grouser]

curious to know how to charge it as far as running it down all the way or throwing it on the charger ASAP after each hunt... I'm thinking it's not a Lit-ion cuz you can charge it off a USB

According to Minelab the WM-10 is powered by a lithium Ion battery.

Lit, Mine stay on charge until its time then right back on when I get home.

that's what I do with the MD batt,,,, will follow suit with the WM,,,,, thanks gents just what I sas looking for,,,,sorry to ask but I have a hard time navigating the cd manual

I don't mean to be negative ,Because I already have one coming. But isn't a pain to take the rechargables Headphone and detector off every nite to charge? Maybe I am old school but that is what I like about alkalines when there dead just replace them. That is one reason I didn't go with the XP-Deus. I'm not sayin, I'm just sayin.

Two clips and the main battery comes right off the back and you set it in the chargers. On the WM-10 you just pop open the access door and plug in the usb cord. What's so difficult with that? It's faster (and much cheaper) than popping in and out AA batteries.

I agree, it is simple and when I head out I know I have a topped off battery. I do carry the AA spare just in case.

I can't say that I know for sure but I would bet the batteries are protected against over and under charging. (smart battery circuit) which is almost a must for Li-Ion batteries. I wouldn't worry about running them down too far. I can hunt several days between charges although daily charging is not suppost to hurt them, I like to run them down at least half way. I'm from the old battery school.....

The best news is that I haven't heard of anyone's CTX catcing on fire or the battery exploding.

I also fly RC planes and we use both Li-ion and Li-Po batteries. Li-Po batteries can be very dangerous and have been known to catch fire when charging. The Li-Ion batteries are much more stable. In fact some pilots actually charge the LI-Ion batteries while still in the planes. No way with a Li-Po. The good point of either is that they discharge very little while not in use unlike NiMh or NiCad batteries. I misplaced a Li-Po that I had charged and found it several months later. It still had over 90% of it's charge left. I am sure the CTX has a battery monitoring system to cut the machine when the voltage drops to a certain level. I think this was involved in the machine turning off software update. I believe if a lithium battery drops below 3 volts per cell it's history. On RC vehicles there is a BEC (battery eliminator circuit) that cuts the circuit when the battery's voltage gets to 3 volts per cell. The Li-Ion is a lot better all around than the Li-Po.

The battery will last significantly longer if you recharge more frequently. Do Not store minimally charged or discharged LI batteries, they may drop below the voltage required for recharge and become useless. LI batteries should not be charged in a hot environment (i.e. inside a hot car) as when the batteries are heated during the charging process, they create Lithium metal dendrites which could short the battery resulting in fire.

I agree, todays batteries like to be "worked" and if possible let it get fairly low befor recharging,,,, not thru multiple hunts over several days but a single hunt for longer duration,,,,
