One of my motherboards has (had) and rechargeable drum battery. I have removed it in order to replace it. I can no longer find such batteries and only can buy normal drum batteries. Should I replace with rechargeable or can I safely use an normal one? (286 motherboard).
Normal won't work as it will be charged by the mobo and will explode - never charge non-rechargeable batteries.
You need to either install a diode to prevent charging or modify the mobo to stop charging or use the EXT battery connector if available.
A recharagble drum battery is $3 on Ebay 😀

4.5V is a pretty typical rating for the external battery connector. If you can get a 3xAA or 3xAAA holder it would work well. Just make sure to place it away from the board in case it leaks
wrote:+20$ other costs 😀
External battery requires 4.5V?
$1.5 with shipping, if it dosnt get through the net, try again 😀

Maybe break up a rechargeable PP3, they are normally a stack of 7 oblong buttons, but fastening connections would be difficult unless you have a DIY spot welder - the other source of these rechargeable cells used to be surplus Pye pocketphone batteries - I used to convert them to PP3!
Alternatively, wire the barrel battery points to a 3x AAA holder and load it with NiMH (or NiCd if you can get them) - NiCd may be more tolerant of sustained low level trickle.
