Sorry, my mistake, that is not the battery I use
although it will work. The YUASA battery with the
perfect form factor for the MFJ-259B is the NP2-12
at ~$48. That one failed after many years of use
and I am going to replace it with an NP2.3-12 at
~$29 which is 1.7 times as thick but is higher
capacity and costs 60% as much as the NP2-12.
