I’ve been using the volt 1600 for some years now. I never knew you could replace the battery. I use 2 on my Brompton, mainly on hyper constant and it definitely feels longer than 15 hours before it needs recharging. I’ve recently upgraded to an ebike and as the 1600 seems to be obsolete I’m looking to get the 1700. That extra brightness is a godsend. You’ll be surprised to see how many drivers hesitate before pulling out in front of you, even during the day as these are so bright. I’d strongly recommend them.
I think my biggest issue is that the light uses a micro-usb to charge. In 2023 or even back when you did the review in 2022, USB-C should be the standard these days.
WARNING: Sometimes beauty is only skin deep. It's a nice, attractive light BUT a chain is only as strong as its weakest link. In this case, it's the base of the light that slides into the plastic H34 bracket that comes with it. The problem is that the release pin spring in the base is not held securely. In fact, it just lays flat in there and not attached to ANYTHING!!! Hard to believe! Thus it comes loose without warning, leaving the light to break free and sprawl on a busy concrete street, mangled and ready to be run over by the traffic behind you. In my case, the light was brand new. Now it's all marked up. And so much for the supposed 2-year warranty. Because if the light stops working, the shop/dealer will claim it was abused, and thus not covered. Going to the bike shop where I bought it, they didn't want to do anything because being banged up is only “cosmetic damage.” Ignored is the inevitable shock to the interior electronics. Despite its attractiveness, it must remembered that this light was made in China NOT Japan....which should be a red flag right there. If the light only lasted only 40 miles or so on smooth streets, I can’t imagine using it for mountain bike trails.
