A battery hack for early porsche 911’s
November 20, 2023
by on November 20, 2023

For anyone stuck for a suitable option for their early 911 this is a strong candidate. So far it’s proved reliable. It’s early days but I’m confident that this will be my new choice for my 1979 porsche 911.

I needed a new battery for my wife's 1994 Mazda Miata, but couldn't find one locally - so I hit the internet. I've done business with battery mart in the past - so I ordered one. The price was right, it came quickly and I'm more than happy with the quality.

I am completely satisfied

I looked online for a battery for my wife's Mazda Miata, and couldn't find any at the usual places I'd purchased one before - that battery had become unfindable unless I paid close to $200 for one. No way, not when the last battery for the Miata cost $75, a good one too! Then I found Battery Mart, they had what I needed at a fair (for these Biden Days) price. They sent it immediately, it arrived quickly, I checked the charge under load before installing it, and it was tops!
Put it into the Miata, turned the key, and Instant Start Up! Much quicker than any battery before.
I am completely satisfied. And have told numerous friends about Battery Mart.

Bought one a while back; lasted for almost 6years; so I bought a replacement and hope it will last at least that long :-)
