Hardware EZFlash Junior new battery dead in less than a month…

[Flandre_Scarlet]

I like purchased a new battery for my brand new ezflash junior (even though it was new, it came with a dead battery…disappointing). I replaced the CR1220 (which is what was in it when I took the battery out) with a new Energizer lithium CR1220

So like less than a month later (don’t know the exact amount of time because I was in New York having surgery and didn’t bring it) I started getting that “battery dry” message and the voltage is now about 0.635 VDC (taken with my dad’s Fluke multimeter)

Anyways, I’m sooo I losing my mind
Can anyone help me figure out what’s going on?
I’d be so grateful

Thanks

This situation is relatively rare, in order to facilitate the identification of problems, whether you can replace a battery again, replace the brand, such as Panasonic.

may be likely a short condenser, try to get the device to a phone repair shop they can try to test and probe the problem

I tested it with several Panasonic batteries.
It was hard to get over a month.
The voltage at which rtc is less accurate is about 2.7v.
time is getting late and then it starts to reset after a while.

I think the osc uses a lot of current, or it's a problem with sram.

The same osc in omega de, but there was no problem.
Maybe it's because it's fram instead of sram.

If I would have the Schematics I could suggest where to look at but without a Schematic I only can guess that the Issue is near by the Battery.
I would check the Capacitors nearby the Battery because a Leaky Capacitor could cause the Battery to Discharge

i checked all caps and resistors.
at least no problem with continuity mode.

Poor battery conditions can cause problems.
So I will buy new cr1225 and br1225 batteries.
also I bought OSC for another confirmation.

It takes a long time to check this.
But I will try and let you know the result.
