Fully charged battery, green light on..unplugged from wall but only lights when plugged in not by itself

It sounds like the internal battery is faulty. Have you tested the time the light will stay on at low setting against what the advertising says 66 hours? The Cree Light module has a current sensor in it and will cut off when there isn't enough current.

This says it takes 8 D-Size batteries, and doesn't mention rechargeable at all?

Read page 3 of the manual.
The red light is on when charging, it does not change colour but goes off when not charging. It will take up to 18 hours to charge for 9 hours of use on low.
12V Lead acid battery should be kept charged all the time, even when in storage.

Throw away

will the main light come on when plugged in? it might just need a new bulb. if so it might be a dead battery

There are several different models of the Swiss Gear rechargeable lantern. On most though, you can remove the top portion of the lantern and check the lighting element inside. In most cases the elements can be removed and replaced. I have a dual filament lantern and from experience I know that every so often you may have to go buy a replacement light piece. If the lantern has been bumped or even just strapped to the outside of the pack while walking, it's possible for those elements to become loose and need repositioning or replacement so do check that. I'm sure that it should be unlikely your charger is malfunctioning unless you left it plugged in for some very extended period of time, in which case I would say the light would be more likely to burn out. But definitely try that and if that doesn't work the battery pack on the lantern itself may have an issue in which case you can always get a replacement.

I just bought a retro rechargeable sealed battery,recently. I charged it for 18 hours,the lights all worked,but I don't remember the green light comming on.i put the lantern away for 3 months or so.i decided to check the the battery light out first week of june, the light was there,then I said let me charge it up again, I never seen any green light come on showing it was fully charged. I took the battery out and checked the wires to see if there was a break. None that I could tell. After you take the battery out ,there is another section square that covers where the bulb is located,but I didn't touch that part yet. Stuck" on this one. Help"

just read the charging instructions. Charge for 16-18 hours. If stored for more than 6 months recharge for the full 16 hours. Do not leave the lantern on after the battery has stopped, has overdischarging the battery can cause problems in recharging to a full charge. If this does happen, switch lantern to off and recharge for 40 hours.YES 40 hours. Only the LED is the only light to be used while charging. If you hane the other light on hi or low the battery does not charge.

Hope this helps

No JJR all the plugs need to remain plugged in. On the Pride chairs the light on the charger will only come on green when the batteries are fully charged. When you unplug the controller the charger thinks the batteries are fully charged and the light comes on. Now the problem is the batteries. If they are old or you have a bad battery then the charger never senses a full charge so no green light. Hope this helps

According to the owners manual for these swimming pool lights, this is what each colored indicator means. Hope this helps.


Solid green
The battery pack is fully charged.
Slow flashing green
The battery pack is almost fully charged.
Slow flashing yellow
The battery pack is half charged.
Medium flashing yellow
The battery pack is less than half charged.
Fast flashing yellow
The battery pack has almost no charge.
Fast flashing red
A charging error has occurred and the light should be unplugged and then plugged back in. If the Fast Flashing Red persists after several attempts, the battery condition is questionable.



Also in the trouble shooting guide, it mentions this:


Problem: Red Indicator Light Is Flashing While Charging

Solution:
A red flashing indicator light when charging indicates a selftest
error condition. Unplug the product and plug it in again.
Try this several times; if the indicator light continues to flash
red, unplug the GlowBuoy and take it to an authorized service
depot.
