Lightflyer, 1940-1953 battery cases will accommodate the Optima without removing the bottom of the case. Make sure that you vent your case enough to allow the Optima to vent the gases when it is charging.

There were some instructions on the internet about emptying and modifying a script battery case as well. I may try that with my old battery.

Putting an Optima in a Ford case requires modifying the battery tray in a 1939 Ford. The Optima is taller than the battery case for the 39 Ford. The battery case must have the bottom removed and then make a cutout in the battery tray to receive the Optima and build a shelf under the tray about 3/8" below the bottom of the battery case. These measurements are approximate, measure your battery once it is in the case for exact measurements.

Check your voltage across the battery poles at fast idle (above 1,000 rpm) and with the lights on, if you drive at night. You should see about 7.5 volts. This is a more accurate method than measuring current (amps). Dash gauges are seldom accurate, and most hand held meters are not able to read the amps without an add-on. If you have the three brush generator system, you can adjust the charging rate. If it is the two brush style, the regulator does the job, but don't try to adjust it or it is likely you will ruin it.

Look at page 134 in the C&G catalog. It is online at cgfordparts.com They sell them in a couple of different styles.

Also,I forgot to ask what is the normal amperage charging rate for a 39 standard while running? Its a stock 6v system. Thanks...

Does anyone make a Ford box that an optima 6v battery will fit into and look authentic?

Put the Optima battery in a Ford script case.

And they are ugly and look out of place in an old Ford.

I hate to sound like a broken record, but the answer to battery life in lightly used old cars is the Optima, hands down. They provide cold cranking power of more than 800 amps, retain a near full charge for months without attention, and prevent acid leakage that destroys battery boxes, etc. As to life, my first Optima lasted seven years, and I still use it as a six volt source for diagnosing purposes. Under the best circumstances, conventional lead-acid batteries seldom last more than four years, if that, providing adequate power.
