What do the LED lights on the units tell you besides that it's just "on". Does it tell you when the battery pack is running out of jiuce?

Lights on- standby. Flickering- charging flash. Blink fast- no battery. Blink faster and faster- that 4 cell group is dying (needs replacement soon). Remember to REMOVE the batteries when not in use for a week or more as the unit does drain the batteries even when not connected (.03mah)

No. It really only tells you that it is active. I only notice the lights when I trigger the flash. They pop on momentarily...I guess signaling that it is active.

I do love the unit though. For the price it is great. It massively speeds up recycle times! ...I am a wedding shooter...and I can't afford to stand around.

I have an indicator, and it shows that the battery is going down. I haven't let it get to the point of running out of power.

there are (3) lights:AC PowerCharging-unit is actively charging the batteryFloat Maintenance -battery has reached full charge and unit has switched to maintenance mode

They have LEDs that flash every 90 seconds to let you know the unit is receiving power but they start to beep (chirp) every minute or so when the battery is low & needs to be replaced

The lights on my charger go out when the batteries are fully charged no matter what size battery. If you don't have one already, buy a battery tester (available from Amazon.com for $2.89) to be sure that the batteries can still hold a charge. If they cannot hold a full charge, this may be a reason why the lights stay on. Otherwise, I would return the unit. Hope this helps.

Not sure... But I bought this and discovered there is No Light or Sound Indicating its on or even working..You will never know for sure whats happening or working or batteries are kaput. A bit disconcerting at best. :)

I am not sure what you mean exactly but the unit has an on/off switch and if you unplug the solar panel while the unit is in the on position the leds will stay on until the batteries are expended.

Don't know for sure, mine are on, I actually cover them with electrical tape when the units are visible. Must not be working.

I have not had this unit that long, but the first unit I had just stopped working. But the lights would not come on rather than staying on. The second one has been working fine. Sorry I cannot help any further.

on off on to me sounds like its done charging and since it sounds like there is no off switch, it goes in standby mode using little power so thats the possible reason for showing the red led again. Just got this for myself for my iPodT5G and my PS4.

Mmmmm I've had this unit for about 4 months and haven't dealt with or heard about any batteries. I just plugged it in and used it. If there are batteries it'll be a surprise to me. BTW I like the light.

I only turn it on with the battery is low. It automatically shuts off when the battery has fully recharged. The battery pack itself lasts a couple days before I need to recharge it.

unfortunately there is no indicator light saying that the battery will die it however does provide a constant beam right until the moment that I won't be able to provide any more power. I recommend to charge it every 3 or 4 days depending on usage I ride home every night and I had a week and a half of power full beam and strobe using it 15 minutes per day

When the LED lights go off the batteries are charged. In my experience time varies with different batteries, perhaps depending on residual charge.

I have already returned both units that I purchased. However, if I remember correctly, there are 4 lights showing the strength of the battery. Not sure about the on/off.

I've noticed the same thing. After a short time they are completely off and do not drain the battery. I don't know the reason for sure. My theory, LEDs have a broader amperage operating range and pick up the residual in the system for a short time. Just a theory.

I don't know how long it takes. I still haven't figured that out. Also there are no instructions, whatsoever. HOWEVER the battery pack led light will change from red to blue once fully charged. I also do not know how long this lasts? smh
