Tektronix DM5010 NiCa 2.4V battery replacement

Ke-Fong Lin

Hi everyone,

I need to replace the backup battery of a DM5010. It has leaked but I cleaned up the mess.
The service manual specifies a Nickel Cadnium 2.4V 150mAH at 14mA.

So far, I was able to find (on Mouser) a 2.4V 110mAH (https://www.mouser.fr/datasheet/2/331/PCBM-2.4_R_complete_11_Jan_25-21018.pdf).
Does it meet specification? In particular, we have 0.11AH vs 0.15AH.

I've absolutely no experience with rechargeable batteries. So I welcome your help.

Best regards
