Thanks for the picture, Gucci, but unfortunately this still doesn't give us the information we asked for to be able to help you.I have two start batteries one house battery, house battery has about 4 volts in it. Is it cooked? Please see the photos regarding the pronautic charger. It appears to be working but who knows. I used a portable charger to charge the house battery. for about ten minutes but when I removed the nods, still nothing. Should o replace the battery or the charger or both?
Please respond to the questions we've asked above.
What kind of portable charger was this? 10 minutes is barely a fraction of the time needed to charge a battery with anything but a high power charger - and even then it's only scratching the surface.
Please don't take offense to this, but if I may be blunt for a sec... if you don't feel comfortable doing the checks we asked about and answering the questions, that's fine. Just say so. Not everyone is comfortable with electricity. It might be best to hire someone to help you.
