AGM Battery Size and Specs

[Sterling Sal]

HI All,

Printed out the info from the site someone clever gave us on here about your actual car (using the VIN) and it said we have a "220 Amp alternator and 800 Amp battery?" How can it be so big??

Is that 800 A/h? I thought they didn't go over 200-300A/h. Who has such a large replacement battery?

Does anyone know the exact size of the battery under the seat please and what size alternator we have?

Also, what size batter charger (C-TEK) would you need to keep it charger over a week if not used?

We already have a MXS7 (7 amp) would we need the 10 amp or even the 15 amp?

Appreciate any advice.

Thanks,
Sally

Its CCA that is being quoted not AH.

Hi,

Thought so, even though it does say Amps!

That makes more sense.

Anyone have any advice on the correct size charger?

Thanks,
Sally

7A charger will be fine. Only advantage (assuming the battery is healthy.) to charging at higher amps is that you can charge faster. But it won't need much after just sitting for a week or so.

I dunno about that alternator but 200A sounds about right.

Ps; its appropriate to call the battery "800Amp", just a bit inaccurate.
A = Amp, is a measure of current.
CCA = Cold Cranking Amps, means the max amps that a battery can deliver when "cold".
AH = Amp Hour, means the number of Amps in 1 hour, or the number of hours at 1amp.

So a 800CCA battery can deliver 800A (kinda, not in reality.) in a burst.
And if it has say 70AH capacity, it can provide 1A for 70 hours until dead-flat.
