Description
Replacement for Eveready 413 battery. Uses 10 CR2032 cells in series. 30 volts.
I used desoldering braid to bridge the two stacks of batteries and create the contacts. Then I wrapped it VERY tightly in scotch tape. There are probably better ways to hold it together but this worked alright. The tape has to be pulled very tight for good contact.
Used two of them for a Simpson Model 651 VTVM.
Someone could make a better more secure battery pack using the thinner CR2025s.
