Ok you multimeter pros, I have a few questions. I want to know how to take tailcap readings, and I want to know how to check my batteries prior to charging them and after to verify they are good and fully charged. Also how do I check the volts on a battery after it is charged? Here's the charger I just received today. Remeber I'm a rookie on this stuff so please explain step by step and how to use and do these things. Thanks.
Set it for DC 10A and put one probe on the negative contact of the battery and the other on the flashlight tube to check tailcap current (the light will come on when you do this).
Set it for DC V to check the batteries and put one probe on the positive end and one on the negative end.
Just check before you charge and then again after you charge.
You say that this is a picture of the charger. I think you mean DMM.
Excuse me for barging in, but is DC10A also used for checking how "fast" the charger is charging the batteries? If so how do you connect the meter to charger?
I'm also looking to buy a DMM, how is that Equus? It's fairly cheap ~$15.
I just checked my Keygos KE-5 and got 3.62 amps at tailcap. Maybe that's why this thing is so bright. That was with a Trustfire flame 18650. The highest was 3.72 and the lowest was 3.4 something I think.
As far as I know, I think the rate of flow (amps) will always go down from the point you start measuring as the battery is being used. Any electrical geniuses care to pipe in?
Well I will know the guys here are very high on the Xtar 18700 2600MAH. The Hi-Max are said to be probably as good from most who have had both. Both costs me $13.50 shipped to my door for a pair. The Trustfire Flames are very good batteries, too. I like the ones I have. There is a guy on ebay that sells them pretty cheap and they are good. I can get you the link if you wish.
Go to electronics and click batteries. Find the Trustfire flame 18650 and select how many you want. Then type this code 10%eBay2011 in the discount code box before you finalize your checkout. It might work for you. That's how I bought my last set but I have received them yet from this seller.
It should come up as $8.53 a pair if it works. you won't find them any cheaper that I know of.
