m48t08-150pc1 battery

[Doug]

anyone every try to open one of these up to replace the battery?
i Know they are still available and you can get the ones with a snap top to get access to the battery.
date codes on this has W2640x also has H992M0035 made by ST.
I'm assuming the W2640x is the date code. How do you read the date code on this ?

No,
The date code is actually H992M0035 (now obsolete),
I have replaced the batt on Dallas Semi.---chances of destruction is pretty high unless you are familiar.

So that's yr 2000 35 week.
So little old.
I had order these before but they wouldn't work.
There is no way to check the battery.
The di make a version with a snap top.
I ask st about the date code and difference in size as these set side by side.
No response so far.
I appreciate the info

I ordered some new ones which dont seem to work.
Maybe old stock
The sets of numbers on this
W3411z, ,,,,,,,9903v,, ,,,,,, ,mys 99 147 E,,,,,,,
Seems different type codes
