So you're on your way to Arctic Alaska to view the Northern Lights when your 6v battery dies in grizzly bear territory. Could one of these 12v babies be used as an emergency start battery to get you back on the road? It's only 120CA but it's 12v...would it work on a 6v system?

4.25 x 1.25 x 3.75 inches (LxWxH)
120 Cranking Amps

Where's your hand crank? lol

M2M · 04-24-2020, 10:38 PM

There is also a 6v version which is slightly larger.

Product Weight 1.56 lbs
Product Size 4.25" x 2.25" x 3.75" (mm: 108x57x95)
Cranking Amps 120
Amp Hours (Pb Eq) 20

Hand crank not an option because "Establishment" guys on this forum talked the owner into installing front tool box which blocks hole for the crank.

Remove tool box. Problem solved. Never look for the most difficult solution.

You're surrounded by Grizzy Bears for God's sake, no time to remove the tool box!

There are any number of jumper battery solutions. I have a small one that is 12 volt but it will kick over my six volt system quite handily and doesn't kill my alternator. I'll try to remember to dig it out and give up the name of it. It doesn't mount to the car, just hooks to a good ground and the starter cable, light if off and disconnect quickly. Might weigh two pounds.

Disconnect quickly because 12v will destroy the coil?

Antigravity?

I wouldn't want that thing floating around inside the car with me

Put it in the front mounted toolbox.

What an awful thing to say to someone...my goodness. What's the next insult? You'll accuse him a having STP in that front toolbox that he uses to top up the transmission???

If I absolutely must shut the car off in bear territory, I park atop a steep enough hill to achieve a roll start.

If the car doesn't start by the bottom, at least the bear worked for his dinner.

Its a little light (antigravity?) on Ampere-Hours.

Those little square 6v batteries used in emergency lights are 4.5 AH.

Jim/GA · 04-25-2020, 08:29 AM

I agree with Joe. The 6 volt battery says on the side "max charge rate 4 amps". It is not intended to turn over a starter motor (100+ amps).

I never hand crank start a Model A. More trouble than it is worth. If someone can push me down the road (or I park on a hill) I can have it running after rolling 10 feet.

GerryAllen · 04-25-2020, 10:56 AM

I don't want to change the topic. However, I am relatively new to Model A's and have heard a small amount of STP in the transmission is a good thing.
M2M, I felt implied it might not be. I am not trying to start anything I would just a few comments as to whether STP should be used in the Transmission.

Gerry Allen, To each his own but I never put additives of any kind into my oils. I use the latest version of all oils, not 600 wt. not non-detergent. Oil companies work with auto manufacturers to determine what is best.

It’s okay Joe. Not even drunk, crazy people drive their Model A to Arctic Alaska. These trips only occur when people are self excluded. Solitude affects the mind!

johnbuckley · 04-25-2020, 11:37 AM

You can certainly use 12v battery to start a 6v system if the need arises , as soon as the car is running disconnect the jumper cable. The antigravity battery spec you list as 120 A cranking which should be enough for the A. ......But maybe it's easier to simply
carry a emergency starter pack which are now really small and cheap.

MikeK · 04-25-2020, 11:43 AM

If you're in a roadster just be sure to take the side curtains along. That will protect you from grizzly bears while you munch on sandwiches waiting for AAA to arrive.

Or you could just bring your .458 rifle along. Then you could shoot the car when it doesn't start. Now eat the sandwich and wait for the tow.
