2016年10月22日 · Hi, I ordered one each of the Copper Astrolux M03 lights (XP-G3 and Nichia) when they were on sale awhile back, and they just arrived today. The batteries appear to be charged (green light when USB cable is plugged in), but neither of the lights would light.

2017年3月1日 · Ok, like normal, tests done the same as all my others. These are the 219B 9080 CRI (basically the highest CRI you can get in a high powered LED). These are not meant as output monsters but as tint beauty queens. I tossed one on the bench just for giggles. The tint is really great, on the rosy side for sure but the CRI really makes colors pop. I have not put one in a flashlight yet so can’t ...

2016年8月27日 · Hi, I ordered my first “Strong Flashlight” which came with 4xUltrafire 26650 batteries and a charger. To be exact it the set looks like here: Battery: Ultrafire CN 26650 7200mAH 3.7V Charger: HG-1206LI Yesterday night i used the batteries in my flashlight and had it turned on untill the flashlight started to fade. After pulling out the batteries to re-charge it seems that 2 of the 4 ...

2024年11月18日 · I have a USB rechargeable portable light, I think the battery is dead as it doesn’t hold a charge and won’t turn on. I found a tiny black rectangle box, measures 1.45v. I cut the wires from circuit of light to the battery, plugged it in mini usb and the wires measure 4.75v. What can I buy from amazon that I can easily repair this?

2024年4月23日 · I heard of a trick where you connect a good battery to a dead battery of the exact same brand/voltage for 10~15 seconds, and the influx of power “restarts” the cell. I did this for all 3 dead cells. Sure enough, they showed voltage. I put them in the charger and they’re actually charging OK so far. Not warm to the touch.

2025年2月2日 · I’m looking to replace my Fenix E16 on my keychain and not finding many good options. The output and runtime is sufficient for me on a single 16340 rechargable, and the size is ideal: Length: 2.0” (51mm) Diameter: 0.7” (19mm) Head: 0.8” (21mm) The only reason I’m replacing it is that its becoming unreliable. Can anything else come close to this nowadays? Anything AAA powered would be ...

2025年1月8日 · I’ve had my trusty Opus C3100 for years, but just picked up a VC8S recently to get some more convenience. Lithium cells seem fine/consistency on both, but I’m getting vastly different NiMH capacity test results on the VC8S versus the C3100. For example the VC8S I started with a capacity test of an older 2450mAh cell and got 1191mAh. I put it in the C3100 and get 1927. Put it back in the ...

2012年9月12日 · They all use “silver” non leaded solder for RoHS compliance. Wikipedia says 5-20 degrees Celsius higher (220+ decrees C), but another pal of mine says that 400 degrees C is when you can get the shiny surface like with lead solder, but that seems a bit high to me.

2024年12月1日 · I’ve bought 3 sets of Energizer Ultimate Lithium AA Batteries this summer (Amazon). 2x 4-pack AA, and one pack of 12 AAA. They do not look counterfeit. I put them in 2 indoor home temperature stations (Accurite/2xAA and ThermoPro/2xAAA) in 7/24. BOTH STATIONS DIED A COUPLE DAYS AGO. Batteries tested around 1.0v. This is the 2nd time this has happened, so it’s not a fluke. Expiration for ...

2021年11月17日 · Truly appreciate this response. That’s pretty much what I figured, but been a little out of touch being busy. Totally confirmed my suspicions. Just wanted a more informed opinion. Thank you. Guess I can put this to rest, especially as it seems i was beating a dead horse unbeknownst to me. Have a good one.
