Both Beetle and early baywindow originally had a 630 battery. Most buses have had bigger batteries fitted though.

If you have spot lights and/or sound system I would use a 634 in the beetle

In a beetle application, where battery lives under the rear seat:
Remember to always re-fit the insulating safety cover that came with the car. Otherwise seat-springs will short out causing a fire.

Won't a rusty original VW metal battery cover do the exact same thing, if the protective isolation on the inside is gone? :shock:

The original insulation in the battery cover was a thin layer of cork. I always add a layer cut from a rubber floor mat or inner tube to insulate the metal cover.

Many, many Beetles have burned to the ground after the seat padding caught fire from the springs shorting out against the uncovered battery when a heavy person sat in the back.

While looking through a box with beetle parts I came across this cover. Never seen one before but the feint sticker on top indicated it was related to the battery.

Hi guys,

I'm trying to get some info on the battery for a 1600 bay window.

I am planning to add a speaker here and there, as well as a camping fridge. Not yet sure if I'll add more, but there is a slight chance.

What battery would you suggest with a setup as described? I'm getting confused as I've seen many different answers to this question.

Thanks in advance

best to use a "normal" battery in the engine bay and a second one to power your auxiliaries. That way if you drain your battery by using the fridge, you can still start the car on the other battery. Seperate the two from each other with a big relay (cheap option)
