Is your free Lezyne Macro Duo still working?

I know lots of people on here snapped them up pretty much a year ago to the day.
Used mine quite a lot. A couple of times I've charged it but the light has never stopped flashing to signify a full charge. It seemed fine when I used it but very prematurely it's showing a dead battery.
I've never had a USB rechargeable light before but I would have thought that given the cost of a light like this it should be lasting a few years rather than one?

Has always made a slight buzzing noise but you can't hear it on the road so it's all ok
If you are having battery problems, I think you can change them. There's a small screw beside the charger USB port, looks like an 18650 battery will fit in there nicely (obvious disclaimers apply
Classic sign of a Li-Ion battery that's near the end of it's life. Suggests the battery was on it's way out when you got it and has slowly been rotting away internally ever since. No matter how long you charge it for it will never reach it's 4.2v max output (just produce a lot of heat, which damages the battery further). Nearly all Li-Ion batteries and battery packs end up this way if not cared for properly (which is another post entirely). Typically after a few years hard use. The runtimes probably got shorter and shorter till it couldn't hold a charge at all.
I'll dismantle it and see if the battery is replaceable.

I had no issue getting the internals of my microdrive replaced/repaired after 18 months.
TBH, even if I had to replace all the batteries in my lights every year (which I don't) I wouldn't be that unhappy; you can get proper Lezyne ones for just over £10 each (I'm never sure how much to trust the cheaper unbranded ones). It's a world away from the Ever Ready lights I grew up with, that took two D cells to produce the barest glimmer (if they worked at all). You were lucky to get 10 hours out of a battery with those things, let alone a year or two...
FYI I just sent back and new Lezyne rear because the full charge even on flash lasts about 30 mins not 3+ hours as advertised, i suspect there are a lot of NOS of this brand out there with cheap censored batteries slowly draining away.

They replaced the internals and battery and sent it back all FOC. Great comms, really helpful and I didn't need to send any paperwork in relation to the censored mag subscription.
cool thanks i'll contact them in the morning, worth a try

charging is slow ish but ive never had to rush it. i get 50-60 minutes before i get the amber light but never used it for longer than 90 mins or so. no buzzing either.
I use it bar mounted and turned off the rear red light. i will probably get another when this one dies as its taken the place of my 2 bigish Electron lights with their 2 ton battery pack.
best free gift ever

Used for the first time today with no issues. It's been sat in the garage for the last year or so.
However, I have a second one which I'd hardly used and that died after I dropped it. The light flashes to show it's charging but it's completely dead otherwise. Quite odd as there was no sign of any physical damage.
Contacted the distributor mentioned earlier, was honest about what happened to it and said it's out of warranty and they said just send it back and they'll fit a new battery! Great service.

The green light flashed while on charge, but never went solid. Trying to switch it on resulted in a quick flash, then nothing,
However, there's light (see what I did there
I decided to try and dismantle it and replace the battery. After removing the 3 screws, no amount of twisting or pulling could extract the inner workings, though I could feel a slight clicking as if it was loosening.
I pressed the on/off button again, and........................it lives
Screws back in and back on the bike, fingers crossed
Edit: Just found this battery replacement guide for the Micro Drive rear light, a similar but smaller looking light. Construction/design looks the same so it may work

Exactly the same for me.

They confirmed there's no way to change the battery yourself.
Following this guide (I mentioned earlier)

It took 5 minutes, and is easy to do - if a little nerve racking.
The rubber button just picks out, you'll need a small flat screw driver to poke it back in place, then give it a twist to make sure it's seated properly
I had to bend the battery connections a little, as it lost the connection when replacing the power unit (switch it on before re-inserting so you know it works)
Use a finger to push the lense firmly into place
The Lezyne battery is a 3.7v - 2400 mAh battery with circuit protection
Once you've done this, the internals can be removed by hand (it'll still teke a reasonable amount of force), as you will have shaved the retaining lumps of plastic. As long as the front lense, button and rear lense are securely fitted, I don't foresee any waterproof issues. If there are, I reckon I've had my moneys worth out of it by now
Only had to fire it up a few times and it's not let me down.
