Re: Tricks and thoughts about the 3457A battery


 

Hello Joel,

I was thinking it is the version with 4 holes. I found the same design
in 2 of my Meinberg GPS167 units. One had a battery holder with 2 pins
and one had a battery with 3 pins.

I looked around for 4 months for a battery holder for the BR2/3A or
CR1/2AA with 3 pins for my E4418B and found nothing. The Agilent EPM
series have the same battery type BR2/3A but the PCB only has 3 holes
exactly how the battery is. There is no 4th hole between the two (+) pins.

Can I ask which model of the battery holder you bought? Do you have a link?

Thanks for the pictures and details.

Best regards,
Razvan

Hello Razvan,
You are right, the original battery has 1 pin on the (-) end, and two
pins on the (+) end. However, I found that the PC board has three plated
holes on the (+) side including one in the middle, which makes it
perfect for a standard battery holder with 2 wires. Please see the
attached pictures.
Have a great day !
Joel
