maximum charge rate for SLA batteries?

Thanks James,

The reason I ask is that I'm designing my system around daytime use only..so the battery is being used as a "buffer" only. IE: if my 12v DC loads exceed the current amp output of my array, then the extra needed amps are pulled from the battery. With that being said, as I increase my array to power more of my studio, I'm concerned that when the battery gets a little drained from supplying a couple of amps for an hour or two, it will suddenly get charged with the full 12amps from my charge controller. The 12v battery I have is only 32Ah, so it would be getting charged at like c/2.5 which might be too much?

maybe there is a better way to distribute DC power directly form an array, without the use of a battery? Not sure how one would go about this, and keep the voltage regulated to a constant 12v output....

Any ideas?

James
