So I've read raving reviews of the Optima Red Top battery... My 1925 Ford Model T needed a new battery so I thought I'd try one out 6 volt, 800 CCA and 1000 CA - and apparently they're vibration resistant and will tolerate sitting idle for extended periods without losing charge.... we shall see...

Here's the video...

An Optima will fit in a T battery box on an angle like the video shows. I had to make a plywood bottom to bring the battery up to the correct level, so the battery cables would be in the proper position. I still haven't figured out how to mount the lid though. Also, I nailed two strips of wood on each side of the battery to keep it in place.

If the car is not driven often, a battery tender to keep a full charge is a good idea. If I've understood the comments of the electrical experts correctly, that assures maximum battery life.

I can say for sure that a battery tender works well and is necessary to extend battery life.

Nothing kills a battery faster than not using it.

I have 2 battery tenders that I alternate between my T's and tractors.

If you buy a high dollar battery, install it and expect it to start your car 6-8 months from now you might be in for a big surprise.

I put a battery tender on my Optima and it fried the wires and burnt my hand in the process. I sent a note to Optima asking about 6 volt chargers for their batteries. Here is their response:
Hello John

Recommended Charging Information:
Alternator: 6.65 to 7.5 volts
Battery Charger (Constant Voltage): 6.9 to 7.5 volts; 10 amps maximum; 6-12 hours approximate
Float Charge: 6.6 to 6.9 volts; 1 amp maximum; (indefinite time at lower voltages)
Rapid Recharge: Maximum voltage 7.8 volts. No current limit as long as battery
(Constant voltage charger) temperature remains below 125F (51.7C). Charge until current drops below 1 amp.

Thank you
Mary Jo
Optima Customer Service

Don't know why it blew up that float charger which I have been using for a couple of years. Got one for each car but a little scared to use it on an Optima again.
