Re: Vehicle Battery

Not with AGM batteries.
There is virtually no liquid, sealed no fumes.
And a vent connected to the outside just in case.
AGN batteries can be used in all positions on IE on their side.

Re: Vehicle Battery

Balance? weight distrubition? Your kidding, right.

A battery weighs, what....40 lbs. So if aunt Sopie sits in the passenger seat and she weighs 165lbs then the balance is a bit off isin't it?

Re: Vehicle Battery

better let aunt Sophie sit on the front fender and see how the handling is!

Now thats a thought. I just laugh when the sales people try to sell the balance, or weight distribution theory to people. Its even funnier when they buy it.

I buy it. The weight distribution wheel to wheel or front to back is probably marginal at best. However, top to bottom I believe, makes a big difference. I'm guessing the battery now sits about 18" lower than it did before. I don't remember my torque equations from high school but 40lbs weight 18" further away from the centre of gravity applies much more force than the 40lbs at the centre of gravity.

Re: Vehicle Battery

AGM battery life is supposed to be around 4-7 years...

Aside from freeing up room in the engine bay, the battery is better protected in a collision, which may mean that important accessories could still work (lights/windows/locks etc.).

Sounds good but when you add passengers and cargo it changes the balance so a 30-40 lb battery really doesn't matter. Then there's the fuel. The balance is changed with a full tank vs a half tank vs a quarter tank. Thats why I find the battery position maintaining any balance is basically mute.

Yeah, marginal at best, especially if you put roof racks and cargo trays up above

Maybe on a race car when 1/10th is needed with improved handling. Milous' post makes the most sense for the positioning.

Re: Vehicle Battery

There's also temperature considerations.

Heat kills batteries (it just isn't often noticed until winter when the cold had reduced the battery capacity to where it won't crank anymore). Under the hood with the engine is a rather hot place, especially in the summer. In the passenger compartment or trunk it's protected from that extreme heat, giving longer life. You also free up not quite a cubic foot of room (depending on vehicle/battery size) under the hood, which is a massive amount of space in an important location.

The only reasons to place the battery under the hood are for ease of maintenance and reduced cable length. Neither outweigh the benefit from protecting the battery from extreme heat, cold, and collision forces.

You are correct in the fact that each component yields a very small benefit. But, collectively, it can have a substantial improvement in weight disribution, lower center of gravity, and reduced weight.
