How bad is it not to charge the battery fully?

Can an 8V battery charge a rechargeable sealed lead acid battery? How long will it take to fully charge?

  • Answer:

    A .4ah battery will deliver 20 milliamperes for 20 hours if it begins fully charged. You can test your home made cell by finding a suitable resistor. To limit an 8v battery to 20ma, calculate V=IR. If 8v=20ma×R, then R = 400 ohms. Put a 400 ohm resistor in series with your multimeter, with your multimeter on ma scale. This should answer some of your questions.
