You need a vice with padding to hold the battery tube. A heat gun to warm up the glue and a rubber strap wrench to get some good leverage on the head to twist it loose.
Sorry about the auto-corrected response earlier. I fixed it.
They should pay for return shipping or else just send a replacement light.
They shoot themselves in the foot by gluing it shut. Instead of sending a replacement driver (which most folks here are capable of swapping), they have to send a whole light.
I just got this light and the ODL20C. Both of the manuals say the charging LED goes from Red to Blue at completion of charging. Both of my lights slow blink Red when charging and then go solid Red when charging complete. I verified this by measuring cell voltage out of the light with my Fluke 115. Both are at about 4.18x. I even put the cells on my icharger 4010 and ensured they terminated at a 4.20 V charge at 10% termination current. Put the cells back in the lights and plugged them in and same result. Both are solid red. I left them both plugged in for an hour after turning solid red hoping for blue but no dice. I’ve never seen the Blue?
Maybe they got the manual wrong. I’ve got the early version, like Lock, with no USB charging so I can’t help much. Manuals are wrong all the time, though. It’s possible their prototypes used red and blue, but they may have simplified it for production. Let’s see if anyone else got a blue led.
OK, will sit tight and hope someone else will chime in. Another interesting occurrence. With the ODL20C, when fully charged from a tiny high Amp Samsung Galaxy8 120VAC charge cube, when the charge is done, the LED goes from slow flashing Red to fast flashing Red, - almost like what is described in the manual as the “low battery, charge it up” alert - which I have not yet seen as I have not run the battery down. With other charge cubes, this does not happen. It terminates with a solid red.
There are some low resistance, higher wattage sense looking resistors, but it’s a boost driver which I’m not very familiar with and frankly it’s output is good enough already.
The switch honestly stinks tho, it’s not responsive at least half the time I use it. Very disappointed with Lumintop for using such a bad switch in this light. I wouldn’t mind replacing it, just never found one yet. (Also haven’t looked very hard)
As far as I can tell its positioned properly. I’ve had it all apart and cleaned it but it is either unresponsive when pressed or it skips modes. I can feel and hear it clicking but it doesn’t work properly sometimes, other times it does.
