Does this have overcharge or overheat protection? Can I leave the battery charging until I need it?

It stops charging the battery once it's fully charged. I have not had it overheat.

It has no indicator that I know of. I have left it plugged in for days at a time with no problems. I didn't know you could overcharge it. It is one of my prize possessions, Use it all the time everywhere.

I do not know if there is a mechanism to prevent over charging. For your second question: there is an LED with various patterns of blinking to indicate charge level. "Slow red blinking: 0-50%. Slow green blinking: 50-80%. Fast green blinking: 80-99%. Solid green: fully charged."

Mine doesn't overheat but it doesn't completely charge the batteries. I quit using it and bought 2 more of the type of chargers that come with tools.

No overheating here. I use it to charge tablets and my 10,000 Mah anker astro. Works perfectly.

I have never had the phone overheat. I have had it on for quite some time. That only issue I have is the charging port and how some chargers do not fit in there properly. In that case, you may have to remove the case.

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.

I don't think you can overcharge the battery with the charger. It has an automatic They last a bit longer than the original one. But not much of the difference.

The instructions say "You cannot overcharge this unit using the AC charging method." However, elsewhere in the manual it says "overcharging will reduce battery life." But if you charge it DC you should not exceed 6 hours of charging time.

Yes. It will shut down the 4 led status lights even if left in charge. So no overcharge or heating issue. Unplugged it will last a very long time I tested a week in stand by and still all 4 LEDs on. Good product . very happy with it

You can leave it in as long as needed. The light will change color when the battery is fully charged. However, once it is fully charged, it should be removed because overcharging can damage the battery and shorten its life.

You will not overcharge if using the Digital charger supplied with the product, It automatically Stops charging. Also Ultrafire's 18650 batteries have built-in protection. They are quite good and hold up pretty well to abuse

You cannot overcharge the battery so don't worry about it. Also no harm done if you undercharge. I have had mine for years, and to be honest do not charge it regularly, and have not had any problems. These are really just guidelines.

The unit does come with an instruction booklet, but does not mention a concern about the panel itself overheating. I am going to leave my windows cracked to alleviate some of the heat, but the warnings do mention a concern over the connected/charging electronics themselves overheating in the sun. I plan to place the electronics in the charging pouch, and leave my windows cracked a little to avoid the greenhouse effect on the inside of my vehicle. I think this will work fine. I have had my phone overheat before in the direct sunlight, but in the shade it works fine, so I have a feeling that it should recharge no problem in the pouch.

It has a gauge you calibrate according to outside air temperature before starting charging. Personally, I just use the gauge to get me into the green zone on the gauge, or when the system is blowing cold air on your hands (in the vehicle). Overcharging will defeat its purpose.

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 am not sure that anyone could truly answer that question. It all depends on the battery. I think it might last about a hour on a full charged battery. I don't think there is any overheat problems. You can always buy extra batteries and simply plug one in after the other has gone out.
