Mixing batteries. Is it safe?

[Noel989]

I've already noticed many member pushing upwards to 10K, which I find ridiculous, but at the same time, I'm not into the Comp scene.

I know theirs poeple that run 10k+ and don't compete

Number of watts is irrelevant to whether you compete or not

AGM/Gel Cells are also lead acid batteries. They're actually called valve regulated lead aid (VRLA) batteries and the appreciable differences between them and wet cell lead acid batteries are the facts that they can be mounted in any position other than inverted, they rest at slightly higher voltage and they tend to last longer than wet cells.

There is nothing at all unsafe about mixing wet cell and AGM lead acid batteries, nor is there anything particularly unsafe about running wet cell lead acid batteries inside a vehicle's cabin space (the Corvette battery was right behind the driver's seat in the early 70's, iirc).

If you do run wet cell lead acid batteries with VRLA lead acid batteries here's what will happen.... when the vehicle is not running, the wet cell lead acid batteries will rob a few tenths of a volt from the surface charge of the valve regulated lead acid batteries.

That's it. No explosions. No batteries fighting one another (heard that one recently). No zombie apocalypse.

Sorry. I'm sure the last one would be kinda fun.

If you hear a hissing sound or smell something funny dont stay in the vehicle if you like your lungs..
