Inexpensive Smaller Battery for Stored 1979 911SC
I've owned this vehicle since 1985 and it has basically been "non-operational status" in the last 15 years, starting on occasion and rolling around the local area to keep fluids flowing.
I'm in sunny SoCal and do not require lots of CCA. Although I keep it on a trickle charger, I have gone through several batteries. I simply need a battery that'll get her fired up and I don't want to handle those monster sized batteries anymore. Does anyone know an option for an easy, smaller, low cost replacement? Thanks in advance! |
Install a battery cutoff switch...then put in an Odyssey battery. The battery cutoff is the only way you will always have a fresh battery.

Avoid using a trickle charger that doesn’t know when the battery is fully charged. For full-time charging, use a battery maintainer with “smart” circuitry. Many out there.

The standard smaller replacement is a glass mat H6, but I have an even smaller H5 in my Targa and it fits great.

As for a temporary battery, assuming it’s just for storage, periodic running and budget is an issue, purchase a pre-owned good battery. Interstate usually has a large wall of good used trade ins for $20-$30. If it doesn’t have to nestle into the factory compartment, all the more flexible. Sherwood |
Since there are other vintage stored vehicles in the same situation as this one--Would it be a good idea to simply acquire and use a lithium jump starter?

Battery tender jr. $25 at most flaps or online. Works great.

I found a 300CCA 12 volt garden tractor battery for $55 at Lowes and used it as a temporary for my longhood. Fully charged and maintained, it should start your car.

I use a battery sized for Harleys. Works fine except when it's super cold which shouldn't be an issue in your case.

.cheap and cranks the engine just fine - also carry a spare just in case - and easy to replace at the parts store in an emergency (which we had one race day) . . . but, the wire connections are small bolt/nut type - not the usual car battery type . . . we also run the radio, cool shirt pump, trans cooler pump and fuel pumps off this battery with the alternator charging of course . . .
