One of my Milwaukee M12 power packs for my cordless powertools went “KAPUT.” Crap! Replace? New ones here in Canada go anywhere from $50 & up. Prices in the US are much better around $30 but that means either going down and buying them or ship them close to the border and pick them up (30min drive)…
Then the imaginative a light bulb appeared. “I can put 3 brand new Samsung Li-On 18650 batts I have lying around and I’ll pretty much have a new batter pack, right?” Not really. This is how the date went…
I took the battery pack apart. I found 3 Moli IMR-18650E batteries. I carefully unsoldered the solder tabs and tested them on the MM. They were all 3.94V. I charged them up and discharged them on my hobby charger. They all seemed to take a charge as well. This means the problem lies with the PCB board. Crap!! No way to fix it at least with my abilities nor would I want to spend more time to investigate.
I did some research on the Moli batteries and found out that my Samsung ICR batteries would NOT have been a good fit. These Moli IMR batteries (1300mAh) are designed to put out 10A constantly and their maximum discharge is rated at 20A. Maximum charge rate is 6.5A. I don’t think my Samsung ICR could have performed half that.
Anyways another light bulb appeared. I wonder how it would perform and how bright would my DD P60 bulb would perform with these batteries. Yikes~! 6.1A at first and quickly down to 5.7A. I’m not sure if that’s accurate as my MM is not calibrated and the leads are crap. I mostly use it to do comparative testing only between lights.
ice beers have higher alcohol content because water freezes faster than alcohol and once the ice gets removed, you get a more concentrated product.
ice wines are made from frozen grapes and because the water in it freezes faster than the sugar and other stuff, the result is a sweeter, richer juice which produces a sweeter, richer wine. of course, you get less juice per grape, so the wine is more expensive.
