Is is possible to overcharge the battery? Can you leave it on charger after charge indicator light goes off or do you have to watch it like a hawk?

I purchased this for my husband as a gift and he loves it! He puts it on the charger when the battery is dead or before he travels with it. He has never had a problem with the battery. He leaves it on the charger until he happens to think to unplug it. We love this speaker!

I don't know the answer to this question. Sorry. I just plug mine in for a few hours and have never been concerned about over-charging it. The first one I had lasted for several years before it finally died--probably from dropping it too much.

I've heard that constant drains on the battery can be hard on it, which I find somewhat contradictory (clock, radio saves, etc) but still feel there may be some merit to. I've only used my always-on 12v supply in my car twice, when my phone was important but completely dead.If the camera doesn't have a Charge light, your phone charger should (or at the very least, your phone should show whether it's charging on the screen or not). I'd use that to see if it's switched, requiring the On position (or, perhaps on some models, Accessory), or constant.

Make sure the "on" switch is OFF when you plug it in to charge it, the red light will come ON if its charging. It wont charge if the switch is still "on", like I've done a couple times when I let it run out of power while I was watching it. I forgot to turn it "Off" and it didnt charge when I plugged it in to charge. If that doesnt work, then maybe your battery is defective and you could send it back if its under warrenty still.

Yes it can be charged that way, though you must unplug immediately once charged because it will overcharge using that method. No, it does not have an on off switch nor a charging indicator...

I had this happen to me also. I had a completely dead battery in my car when I attached the charger. I turned the key on and tried the headlights after charging for only a few minutes to check if anything was happening. The charger started clicking and cycling on and off. The noise stopped after a few minutes and it continued to charge fine after that. I believe the cycling is an overload protection. If you experience this try charging the battery while it is disconnected.

There is a charging light that stays on while the battery is charging; the 'maximum charging' light does not stay on the entire time on mine, and mine works fine. So - maybe you should have yours checked out or return it..

I honestly suggest that you should not leave it there overnight so it will not over charge the battery itself. thanks

Haven't heard whether the factory addressed the problem. Mine still works fine, 'knock on wood'. I bought mine a year ago, knowing about the problem. I keep the backlight turned off in hopes that it preserves the life of the display. I've only used the charger maybe 10-12 times, however. I still don't recommend spending the xtra $$ on this unit because it did nothing to preserve my optima batteries. And it doesn't even have an engine start mode.

You can charge that if you can get it to work. I was not able to charge a single battery with mine. It keeps shutting off like it is overloading or something. Total junk. Buy something better. You get wht you pay for.

I have a Makita charger, the indicator light changes when battery is fully charged. It does take about an hour. I've heard that one should not leave batteries on charger for much longer thab an hour,

Best to turn it off then charge it....don't let battery drain totally. I often use it plugged in when it's fully charged.

Check on the battery occassionally while it's charging. Some times if the battery is to old, it will overheat and melt itself to the charger. I had it happen. If it hasn't been charged in quite awhile, the hot pack signal will come on. I took the battery out and let it sit for awhile. Put in back in the charger the next day and it fully charged.

just received your question.Are you using the 110 Volt charger?Make sure helicopter on off switch is OFF when charging.Check all connections and let me know.PS if you have a multi meter check voltage at charger if you know how to.Also always allow 20 minutes for battery to cool after use, and after charging before use.Let me know...

It seems to me that some of the batteries are "juicier" than others. If anyone knows a trick to bolster the voltage, please be sure to share with me. It's hawks that would benefit in my neighborhood.

You probably do not want to have this plugged in all the time because that will "overcharge" the battery and damage it, so you only want to take it to it's "full" level and stop. If you want to have it charged every day to be "freshly charged", after an initial charge you could leave it plugged into a timer that comes on for 20 minutes a day, that wouldn't "overcharge" it and yet would give it a brief charge.As far as current used, the charger probably delivers 1/2 Amp at 12V which means at 120V house power it only draws 0.05 Amps. So you will hardly see that on your power bill.

I assume you mean how does it monitor the battery and then charge as needed? It can't overcharge, so you place it and forget it.
