quick question is it a 77 or a 76

the battery weighs ALOT. al least 75 pounds i dont know for sure ....they ARE heavy.

hey thanks for the info i'll try that

what do you mean by it wont live as long? so will a small deep cycle last longer than an 8d with the same amount of draw? like say 20 amps?....i realize the 8d is for starting and has high CAA . but it also has a reserve. cat batteries in chronological terms last like three times longer than other batteries......but thats not being deep cycled, thats using them like they are supost to be used (starting...and ignition...lighting).
what kind of deep cycle should i use...... i'm looking for a battery that will last a long time without going dead. one that will store alot of energy and not fall on it's face like regular automotive batteries. i was thinking well i've got one auto battery when i hook two togeather i get more life out of a charge so why not just but one big battary in. i am not very familiar with deep cycle battaries but it would seem like they would work better if what i have heard is true..

question...will a small deep cycle out perform a very large industrial battery

[74Argosy24MH]

An 8D starting battery will put out a lot more current than something like a group 27 deep cycle. Where the deep cycle will outperform it is in the amount of times it can be discharged without harming it.

This is a good site for questions on batteries. They have alot of info on everything solar, which can be applied to what we do in RV's as dry camping is not a lot different than off grid power storage.

cool......thanks for the info.
