Does this charger have an automatic shut off / recondition cycle? Can you leave the battery that needs charging in the unit without damage?

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

I'm not sure, similar to other chargers it has a red blinking light while charging and a solid red light when charged. I have assumed that when the solid red light is on it stops the charge mode and doesn't continuously keep feeding juice to the battery. I've left several batteries on the charger for a week or two before and when I grabbed the battery it was not warm at all and I've not had any problems with the batteries.

Hi Donald, The charger cycles back on when the battery looses power. When charge builds back up the charger cycles off.

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.

The charger that is used for these will automatically shut off when the battery is charged.

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.

I leave my battery on the charger until I get ready to use it and the battery is always fresh, the charger cuts off when the battery is charged to the best of my knowledge.......

Leaving the battery in after it's charged won't harm the charger but, it can shorten the life of the battery. Batteries need to be cycled between a full charge and discharge for a long life. A few hours won't harm anything but, I wouldn't recommend leaving it on the charger when not in use.

I don't know of any battery charger that shuts off automatically. I usually leave my charger unplugged until the night when I want to use it. I found out from others here that leaving it plugged in all the time shortens the battery life. That's exactly what I was doing. Since you asked this question, I plugged in my charger with the battery and found out that when the battery is fully charged the red light on the front changes from bright red to a more dimmed red. Hope this helps!

Yes, it does stop charging after the battery is fully charged. Older battery generations such as NiMH need to stop receiving power after fully charged, otherwise this will damage the battery. But don't worry, the Tenergy Smart Charger will automatically cut off charge when battery is fully charged. This is why you see the word "smart charger" in the description.

If by "automatic cut-off" you mean it stops charging when the battery is full, then yes. It does have automatic cut-off.

i believe the charger turns off automaticly after the battery is charged at least some do tho some chargers tell you that you are useing unnecesary electricity by leaving it on but i would suggest removeing the battery once it is charged.

Yes, I leave it in charger so far have no problems, I also have a back up battery because I got alot of trimming to do!

This does have an automatic shut-off feature. It turns itself off if it's not charging or has completed charging after 30-60 seconds. I don't know about the second question, haha, but I can tell you that we have thoroughly enjoyed this charger.

As I understand from the instructions, you can leave the battery in the charger. It will not overcharge.

There is a cutoff and I believe that the unit automatically dissipates the charge slightly if the batteries are left in the unit beyond the charge up time.The marketing blurb states " Automatically protects against overcharge and short circuit." The only danger I remember is in leaving the unit on with no batteries in it at all.

I plop this in the charger without regard for battery cycle but since I don't have two of these to run a side by side life test I couldn't answer your question directly. However, I've had this for over a year now and it seems to be standing up fine with erratic/inconsistent use of the charger.

I believe It will not harm the battery if it is left in charger all the time, because when Green Light on the charger is on it stops charging.
