Dallas Replacement RTC CMOS (e.g. DS1285 DS1287 DS12887)

Description

Overview
Replacement for CMOS RAM. Replaces the potted RTC device. See compatibility list below.
Problem with the potted RTC is that the battery will run flat and there may be no easy or clean way to fix the problem. Some systems will not boot with a flat battery.
Dallas Replacement essentially removes the potting and makes it easy to change the battery, ensuring that your hardware will hopefully stay functional for much, much longer with a simple battery change once in a decade.
Also included is a button for clearing the CMOS RAM.
Size-wise the Dallas Replacement is about 0.5mm wider and about 3mm taller when including the battery holder.
Compatibility list
DS1285
DS1287
DS1287A
DS12887
M48T86
HT12888A (CMOS clear jumper, if present, won't work; clear with on-board button)
May be compatible with other parts as well. Please send me a message and I can see if I can find out if this would be compatible with your specific RTC.
Likely compatibility, but cannot be guaranteed
DS12C887
Ordering information
To further increase the chances of successful replacement; when purchasing, please add as a
message to the seller
information on what your current RTC part number is. Pins will be trimmed accordingly.
If you wish all pins left untrimmed, let me know. In such case, pins will match the DS1287 datasheet with the exception of pin 16 which instead of NC will be GND. Even pins that are internally NC will be left untrimmed.
If no extra details are given, I will send a version where pins are cut as they are cut in a DS1287. This should work for majority of cases.
Installation tips
I strongly recommend that you don't directly solder the part onto the motherboard, if possible. I recommend that you solder a 24 pin IC socket onto the motherboard, and plug the Dallas Replacement into that socket. This way, if anything goes wrong or doesn't work, you don't have to do any additional soldering.
