Can I leave this on the AC charger at all times...does it automatically stop the charge cycle?

You can, theoretically. The battery is a SLA (sealed lead accumulator), the ones you find in UPSs - they have a limited life spawn anyway.And no, it does not cut the charge.I'm keeping it permanently connected to my car outlet - which does not provide trickle charge, by the way. Still has juice for about 20 min.

No, it is a trickle charger (compared to a "smart" charger that automatically turns off) and will overcharge. Please read the instructions, which clearly state not to leave it charging for more than 8 hours. Only charge until the light turns green, then stop. They also state to recharge immediately after use, and every 30 days if not used, to keep it topped up. Apparently they don't want you to leave it in a discharged state.The battery seems to be the weak link in these rather crappy quality lights. I would do everything I can to follow the instructions and not do anything that might damage the battery or shorten its life...

I always leave it on charge overnight. Sometimes a little longer, and it seems to be ok. It is a very powerful light, but the instructions say to only turn it on for 30 seconds at a time, I guess it's because the drain is high, and it gets hot. So, for a quick look around, it's great. But not for continuous use.

Yes you can, but in the long run it's not good for the battery. It also has the car charger.

I have left mine plugged in for 2 weeks or so and it still works good. I know it says not to charge over 8 hours, but I have and it has always worked for me. I keep it at my 2nd home and don't remember to unplug it from time to time, but, it does still work. Probably not the best for it but....

Mine is near 3 years old. Battery life is certainly shortened now (probably 10-12 minutes run time) but zero complaints about its performance. Gets used a few minutes every few days. I have been guilty of leaving it on charge a few days over the years. Certainly been a good value so far. Will likely built my own battery for it when the run time is unusable.

Yes, it has a automatic charger built in to it! Starts and stops when needed but can be left plugged in at all times when not in use.

Yes it shuts off when charged and also shuts power off to the charger until voltage in battery drops to a preset level. I am able to keep the charger hooked up for months without worry.

My wife has made that by mistake on a couple occasions. It does not seem to damage the unit, however it does not fully charge properly. When you go to charge it the next time in the off position it will fully charge.

No. Not while charging. This version does have a power button that lets you turn it off the entire unit when you aren't charging. But after a few days I just left it on, no good reason to do it.

From my experience, as long as the unit is attached to the charger and AC is active, the light stays on. I usually plug it in only when the unit seems low and leave it plugged in overnight.
2036596
Nope. Since it's just a trickle charger, I just leave it on overnight. Seems to work well.

I keep it charged all the time, but I don't know how necessary that is or how long it will hold a charge when it is not on the charger. I do know that if I took it off the charger for any amount of time it would disappear and never be seen again (hence why I keep it on the charger).

No leave the battery in the device. The circuitry detects if the device is receiving power and then charges the battery and runs the device at the same time. When the battery completes charging the unit continues to run on AC till you unplug from the wall socket. It is a nice feature that you can run it and charge the battery at the same time.

To be honest I have never left it on the charger. Just charge it when it gets low you can tell when the speed slows. When I'm done using it I do put on the charger but always take it off once its charged up.

From what I read in the instructions, it was safe to leave it on the charger continuously. However the blue light is supposed to go off every so often, which mine does. So far I've had no issues with storing it that way.

This is a smart charger and as such it senses when to charge the battery and when not to with its built in circuitry. So yes, you could leave it hooked up to the battery indefinitely with no damage. Many people do this in the off season when a battery is sitting and not being used. Otherwise, you could be purchasing a new battery if it sits to long and discharges to the point that it can't recharge.

If I remember correctly this unit doesn't actually turn off if it is plugged into something. The only way to "turn it off" is to unplug it from whatever it's charging.

My red indicator light never has gone off. I am not actually sure of this, but I simply leave the charger plugged in (AC mode) in the evening, then take it out of the charger next morning. I don't see any indication of overcharging or battery memory developing.

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry.

Hi, The item have auto shut off system. You could leave it plugged into the charging. Also, it can be operated during charging. Thank you for interested in our products. Regards, Customer Services

I do not have this charger anymore, but if I recall correctly: it will turn off. However as long as the battery is completely charged it is in my opinion just cosmetic. R.
