    The goal is to rig a computer fan for wireless use. The sticker on the Brushless Fan reads 12V DC, 0.14A, 1.68W. A 12V Cordless Drill has a battery rated at 1.3Ah. 1) Do I need a resistor -- if so, what ohm? -- and 2) how long will the fan run with a fully charged battery?

    Hello Everyone - My 2002 Jeep Grand Cherokee is not driven very often and the battery has had to be replaced twice since 2016. The only drain that I can think of is the alarm system. My question is whether I can simply disconnect the cables and leave the battery in the car - or should it be...

    I own a 2005 Camry that I bought new. The original battery lasted me 7 years and one day I went out to start the car and --nothing happened. Called auto club, service tech said battery lasting that long was remarkable, so he got me going and I went right down to a local chain repair shop and...

    I'm building my own home and so far I've been totally off-grid with a solar powered battery setup. I'm looking into getting connected to the grid because I can't store all of the power I make and also can't run power tools for example because they draw too much power. I'd like to be able to...
