Will the charger discharge the battery if left hooked up and unplugged from 120v for an extended period of time?

It hasn't on mine, but a light does stay on showing it is charged. Maybe after a long time it might. I've gone 2 weeks no problem.

No. Leave it hooked up, just hook up the tender to the pos and neg posts of the battery and plug the tender into 120VAC.

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...

Yes, to a point. While no damage is done to the charger or batteries outright there will be over a period of time be a shortened life of the batter itself. As with any rechargeable power source it is best to deplete it as low as you can before recharging. Leaving it constantly plugged in means continuous heat which shortens the life span of the battery.

It doesn't have a recondition cycle and as far as I know leaving a battery on the charger won't harm it.

Yes, the charger has the logic to stop charging once the battery is fully charged. This is a good plan, especially if you do not use the tool often as you will always have a charged-up battery when you do need to use the tool.

You can leave it unplugged but the battery last 3 or 4 hour, after that it needs to be plugged so it can charge.

No, don't leave it plugged in. It will drain the battery. The green light is cool but it drains the battery slowly but surely.

I would say no. Neither battery I have had ever discharged when plugged in.

It won't hurt it to leave it plugged in, I believe It's AGM type battery, the circuit board is design to the battery specification, so yes it trickle charges the internal battery, without the need to unplug it.

It would eventually charge it, I wouldn't leave it on any battery indefinitely though as it has no automatic mechanism that will prevent overcharge.

Yes, you can. I've tested the charger while connected to a Watt's Up power analyzer, and once the batteries reach a near-full charge, the amperage the charger pulls in begins to lower. Once the batteries are fully charged, the power analyzer shows 0A of current flowing between the wall adapter and the charging base, meaning the batteries are no longer drawing a charge and thereof are not overcharging. You'll be fine leaving them plugged in, though I wouldn't keep them plugged in for days on end just because you don't need them to trickle charge and lithium batteries have a very slow self-discharge when being stored between uses.

No. This charger will continuously charge so after no more than 24 hrs. You will want to unplug the charger to prevent over charging. Hope this helps.

The charger SHOULD turn off or provide a low level trickle charge, so leaving the batteries in the charger should not be a problem. BUT, most of the chargers I have purchased over the years had "fine print" in the directions not to leave the batteries in the charger for more than 24 hours. Why? I don't know, but I make it a practice to remove the batteries after no more than 12 hours.

Oh.. If you are asking if the charger will shut off after the battery has been charged the answer is yes but it is recommended that you do not leave the battery connected to the charger all the time.

Hi Joe. I didn't read the Operators Manual until you asked this question. Under Maintenance and Storage, it reads "No battery pack damage will occur if the charger and battery are left plugged in." Thanks for asking.

No! You will have to buy a converter to convert your voltage from 220 to 120 voltage for charger to work properly, otherwise you will burn it up.
