Already cold as hell for Oct and several inches of snow on the ground here, doubt there would be hardly anyone out Trick or Treating regardless unless the weather takes a sudden turn.
It looks like an OEM LG battery. I don’t know what the connection to Keeppower is. Typically Keeppower will at least rewrap the cell with their name on it. It’s possible you have a fake HG2 cell. The only way to be sure you get genuine cells just to get it from a reputable source. In your case I would try to measure it’s capacity to see if it’s around 3000 mAh (drain only to 2.80v then recharge and should be around 2800 mAh) Try it in some lights. If it works well, keep using it. If you have a clamp style ammeter you can measure the amp draw on turbo and see if it matches what other people have measured. If it’s way less amperage, then it might be a weak fake. If it’s very similar amperage, then it might be legit.
Do BG sell fake batteries? I thought they were pretty legit since they dont have 3rd party sellers. But this being free kinda seems a bit sketchy, altho it is only 1 battery, and i think its for new user’s first order, so its not that unreasonable either
They do their best to not sell fakes, and if you get one they will refund your money.
This situation seems a bit different because it’s being included for free. Maybe it was sourced by Astrolux to be included with their light? I really don’t know. I wouldn’t worry about it unless it’s performance was bad.
