hi everyone,
does any one have a fast charging circuit that can charge a sealed lead battery 12volts-100ah or higer .i need something that can charge the battery up in an hour or less.please recommend any circuit i will be very greatful

 

There is No Such thing, at least not a Practical One.

Charging a car battery at a voltage Greater than about 14.5 volts will damage the battery, mostly because of Heat.

Initally applying 14.5 volts will give a High Current Charge to a dead battery, But as the battery voltage rises the Current is Reduced automatically.

In most cases the Final charging to a Peak charge can take a Day or more.

if so does any one have any circuit of thatb sort at all or a link to a web site.i need a circuit with good explanation

 

Hiya Drom,
From the size of the battery and your location I'm guessing you want that battery for remote power :?: If so then a wind generator would suit your needs provided you had a good location for wind harvesting. Check out otherpower.com as they have some good idea's and it's not too technical either.

Cheers Bryan
