Work just fine for emergency use...i just charge around 30 minute 18v laptop charger with electromagnet diy...now i can start my car...thank you so much
Dude you’re a genuine smart person. Thanks for the simple ways to recharge a battery with house hold items. Much appreciated. TAKE THAT MAZDA TAKE THAT FORD TAKE THAT MIDAS TAKE THAT NAPA TAKE THAT MECHANIC THIEVES BRA YOU ARE THE BESTO
Interesting. One issue is that the voltage reading of a lead acid battery does not tell you everything about it's condition. Right now, my car battery reads a solid 12.6 volts but will not start my car as it does not have the amperage to do so. I can put it on a 6 amp charger for 3 hours and, it will start my car...once...then it is done. Time for a new battery.
I'd recondition it first, swap out the acid and distilled water add Epsom salt and the clean the terminals. Then trickle charge for 48hrs... Da Daaa New battery.
nice explanation, by the way, while charging what's the voltage to not exceed?? i heard is 14.5v is it correct? please tell me recommended voltage for start using battery
yes that's right 14 volt, you can even charge with 12 volt charger, 12 volt charger won't charge the 12v battery fully but it won't over charged it so even if you forgot that you are charging your battery there's no harm to the battery :)
im using a constant current buck converter set to 14v from 19.6v laptop charger. but it's getting pretty hot. but i only got 0.18 amps. i guess my battery is still in recovering phase since its been stocked discharged around 3v for almost a year 😁
Can I use 12 volt DC adapter and a bulb to charge nanogel motorbike battery . The battery manual mention need ,1.5 or 2 v to charge for 10 hours. Can I know what type of bulb should I use . Thank you
Hi man, I tried the bulb technique as I have a 19.5V charger. At first the bulb turned on, but it started to get dimmer and dimmer until it turned off completely and the full voltage went straight to the battery again. What could be wrong? Do you think I should try the bolt instead? Thanks!
I've hooked up my 18.5v laptop charger with a bulb but its only outputting 12v and the battery isn't charging, shouldn't it be 13-14v to charge the battery??
