Title: 3902 battery conversion
Post by: wizeone on October 24, 2017, 09:49:48 AM
Hi again guys,


  i have like 20 3902 boards with Main Battery Low's.  i have seen where there are adapters that can be soldered on to allow for easy battery replacements in the future.  has anyone done this on their boards? if so how hard was it to do? does the battery life stay the same or go down?


any good soldering stations you would recommend?
type of solder?
any specific battery holder?


thanks in advance

You should be able to find someone to do the work. Might try TV repair Cell phone or computer repair.  Auto stereo installation.

Ya just unsolder the yellow battery, solder in a battery holder and slide in a 2354 battery, you're good from there. I have all my boards setup like this.

Here's some thoughts from the other side (literally) from Buzz, one of our beloved members! I KNOW he's looking down on this subject!!

Why I don't like battery holders, I'm going to ansewer a question with a question.
 Have you ever had a flashlight that you had to beat the crap out of it to get it to work ??  Why does this happen , because the battery/battery's are loosing contact with each other, the bulb, or maybe ground. What if all those items were soldered to each other, ansewer no place to loose contact. Same thing on a MPU, use a holder and maybe it will loose contact and maybe it won't.  Solder the battery and it will not loose contact.  That's just one more maybe I don't have to worry about. Plus it's a little cheaper not to use a holder, look at all those Penny's I don't have to stick in a holder to make better contact.

And CV slots supports his "new" comment:

I have to agree with The Buzzard on this one...man that hurt to even type it... :rotfl:

Battery holders are just one more possible point of failure. How many times do you have to change a battery? Once every 3-4 yrs??? Maybe even longer???

Had a guy the other day who TAPED a coin battery to the board with blk electrical tape....He couldn't figure out why it wouldn't work :Scratch-Head: :Scratch-Head: , as he had snipped off the original yellow coin, but was "smart" and took care to leave the legs so he could tape to them..... :24: :24: :24:
