Duralast Gold specs

I am trying to see what this amp does as amp per hour?

its 850cca and 1000ca with 150 minute reserve. Its the biggest duralast gold battery made.

Anyone know how to figure out how many APH this does.

Thanks

You cant just do some math to figure out Amp Hours. This is done by a test that looks at how many amps can be drawn in an hour from a bat before the bat reaches its depth of charge (aka the battery is dead).

Amp-Hour Capacity

All deep cycle batteries are rated in amp-hours. An amp-hour is one amp for one hour, or 10 amps for 1/10 of an hour and so forth. It is amps x hours. If you have something that pulls 20 amps, and you use it for 20 minutes, then the amp-hours used would be 20 (amps) x .333 (hours), or 6.67 AH. The accepted AH rating time period for batteries used in car audio systems (and for nearly all deep cycle batteries) is the "20 hour rate". This means that it is discharged down to 10.5 volts over a 20 hour period while the total actual amp-hours it supplies is measured. Sometimes ratings at the 6 hour rate and 100 hour rate are also given for comparison and for different applications. The 6-hour rate is often used for industrial batteries, as that is a typical daily duty cycle. Sometimes the 100 hour rate is given just to make the battery look better than it really is, but it is also useful for figuring battery capacity for long-term backup amp-hour requirements.
