Why is the output voltage listed as 12 volts when the EN-EL12 battery is a 3.7 volt DC battery?

the output voltage should be 4.2V and output current 300 mA. if you look carefully at the picture you can read this, but it is wrong in the product description. the 12V refers to the car charger input voltage. why 4.2V for a 3.7V battery? it is common for chargers to be at a higher voltage than the battery it is charging. there are sensors that detect what voltage the battery is at and once the battery is close to charged the charger lowers the current applied to ensure that the battery is charged thoroughly and quickly.

It takes more than the voltage capacity of the battery to charge it. So 12 volts charges the 3.7 volt battery.

It is two 12V batteries, if you wire them in parallel you will get 12V but double the capacity (this is what I did for my boys' power wheels, now they drive forever). If you wire them in series you will get 24V.

theres no difference, but i would check the battery part number make sure its 7 to 12v and the battery u should be ok

I am not sure never had any reason to change batter was in mine ? I have more then one kind not here or would check to see what terminals they use ? I know one type used 2 6v batterys and outher uses a single 12v . Soory not a help Randy

The technical details say: Capacity: "10000mAh / 37Wh", which means (if I correctly understand how electricity works) that the 10,000 mAh is based on the 3.7v output (3.7V x 10Ah = 37 Wh). This would correspond to 3,000mAh at 12v (37Wh/12v = 3.08Ah), assuming perfect correspondence (no loss), which is probably not the case. So, expect less than 3,000 mAh at 12v in reality...

Do not know what kind of battery that is. My experience is with a lead-acid battery for a tractor. It I believe is 12volt.

It says its operating voltage is DC12V 60mA which, using ohms law, would mean they would draw 0.72w. --&gt; 12 x 0.06 = 0.72

Yes, I ordered one and the two output terminals on the back are indeed 12 volt. Good luck.

Hi Elsa: Pre-2014 DeWalt DCB120 12V Max packs are 1.3Amp/Hr capacity. 2014 and up DCB120 production are 1.5Amp/Hr capacity. One must ask to Seller WHICH they are selling. Better idea is DCB127 XR 2.0 Amp with about 30% more run-time for flashlights and other 12V Max tools. Amazon has them here DCB127 2-Packs and here DCB127 Single Pack. Although, I bought a pair on Ebay for a bit less. Cheers!

Your using 4 each 12volt batteries in series to obtain 48 volts. The model BM 12117 is 12 volts only and will not handle 48 volts. You will have to take the 12 volt batteries out of series by taking the battery cables off each battery and charging one 12 volt battery at a time. You can make some jumpers and put all four 12 volt batteries in parallel (all positives connected together and all negative together) and charge all four at the same time with BM red going to first positive battery post in the line of 4 + post and BM black going to first negative battery in line of 4 - post, since this connection set up is in parallel then your only dealing with 12 volts unlike the series which equals to 48 volts.

The output of 3 volt can be done but I am not sure about 12V I would need to do a test. Will keep you posted.

I found out that the battery is a 2123, which is the same as a 12v. It would have been good for them to put that in their manual. The battery was at my local grocery store. I hope this helps.

I went back to my order summary, it is listed at 7.4 volts. I think if you click on the batteries you are considering scroll down a bit I found the voltage near the bottom of the listing

Usually one cell holds 3V. This battery is at 11.1V because of the drop down voltage. Do the math we will get 12/3=4. There are 4 cells on this battery.

I don't know about the numbers and what part they are but, I have been able to use my 4.0 XC 12volt battery with every 12 volt tool I own (about 9 of them) and charge it on every 12volt milwaukee charger I have come across. This battery is awesome and it the one I use every day.

The output is indeed 12 volts, but the label on the power adapter states 12v AC. I've never before seen a power converter that put out alternating current. I suppose this this could be a misprint on the label, but I can't say for sure. It is clearly marked Input 120v AC, Output 12v AC. I double checked. It could be that alternating current is necessary for this type of device.

I bought it for a 19.2 battery and it works great. The bottom says the output is for 12-19.2 volts. There also is a model number of 315.ch2020 on the bottom. I hope this helps.
