If you go back and read all my posts and the ensuing entertaining ones from one particular poster who kept saying over and over and over that those batteries were not Li-Ion and even took pics of the bats to prove, problem is, like you discovered and I knew from owning the light is that they are Li-Ion bats.

And unlike what the same poster said, that light does run for 2 hours on high, I've done it to see if it would and it does and did it just on rides. What's really cool about that light is that after running on high for 2 hours it doesn't just turn off instead it turns to the second setting-low, and will run on low for another 2 hours, I know this because I've done it.

Word of advice, which comes from Philips, when you get your light do not turn it on and charge it for 24 hours REGARDLESS when the charging light says it's charged which will be about 2 hours or so after plugging it in. Then when you use it completely drain the light without recharging it till the light is dead, then recharge fully which at that point you can follow the charge ready lights. Do that cycle 3 times, after that you can freely charge and recharge anytime you want regardless if the light is fully discharged or not.

I really like this light, it has a glowing ring which gives it good side visibility, if the top part of the ring glowing annoys you you can cut a piece of black electrical tape and cover the top part of the ring, but I haven't found that necessary. I believe once you use you'll like it too, what bizarre is that Philips stopped making the light, I don't get that. I've seen this before in the marketplace, someone makes something really good and they stop making it and make something else not as good.
