Willard Battery Topper to fit a Deka/NAPA battery

Post by Rustman » Sat Jul 03, 2021 4:20 am

This has been in development for months. Working from an original Willard SW-2-116 battery, a 1944 Willard catalog, a 1943 Association of American Battery Manufacturers service manual, original and archival photographs of installed batteries, support from fellow G503r Bryanbdp who is also a CAD draftsman as well as design help and advice from several other Jeep owners and restorers we present the “Battery Topper”.
This is our pre-production prototype. We are still doing the final design of the cell connectors and sorting some production details. There will be another announcement when these are available for sale.
“Battery Topper” is designed as a drop on cover for the NAPA/Deka Group 2 Commercial batteries. This cover requires no modifications to the battery and can be installed in minutes. The caps are simply glued to the stock battery vent caps. In the event you need to replace your battery, even while on the road you can simply switch the caps, move the cover over and return the old battery for your core fee without losing the “Battery Topper”.

Here it is on the bench fitted to some RFJP battery tray, hold down and J hooks:

Here it is installed in Mat Curtis' MB.

Hey great work I was trying to do something similar here in the Uk a couple of years ago for my personal use/ but could not get the top thin enough to get the terminals to fit nice. I was just going for a generic old style battery. my business is auto repair and I can get modern 5 year warranty batteries for about $110 as opposed to an original style 1 year warranty battery for $200. can you update me when you are in production or let me know who will be retailing the product regards simon smith.

Is this a 12 volt battery? If so, what's the model number?

Sorry no. Group 2 Batteries are 6 volt. Here's a handy reference site for battery group sizes. It's an industry standard thing. the WW2 Jeeps and Dodges used a Group 2, the G506 series a Group 4 or 4EH as did the M29C.

https://www.batteryequivalents.com/bci- ... chart.html

You'll note that even right up to modern batteries that 3 cells are 6 volt and 6 cells are 12 volt. I guess there is only so much juice you can squeeze from a single cell of a battery.
