capacity of lead acid battery
|
|
|
| Hi,
I am wondering what is the charge capacity of a typical lead-acid
battery. I want to store a total of 500 A-hr in 4-5 batteries, so I want
to calculate how many cells I would need. I would appreciate any advice.
Thanks.

| You need to specify the voltage and application as you can find single
lead acid batteries that are 500 AH (or larger), but they may weigh 500
+ lbs. The application is important because some batteries like
different discharge regimes.
The little 2 x 3 x 6" SLA's are about 12V @ 7 AH.
A typical 12V car battery is typically in the 100 AH range.
Hope that helps.
Provide more details and someone here can probably help you.

Best way to go would be 6 6v golf cart batteries. They withstand repeated
deep cycling substantially better than marine batteries. That would give you
on the order of 555 MAh and 12v for $300. They will probably outlast marine
batteries by a year or 2 as well.

Filtronica has a 12V solar battery (MK US2299U) that has 225AH capacity for
$106.68 including shipping.

You could get 450AH in two batteries cheaply.
Hope this helps,
Jerome
