Can some one give me an idea on how long these 2600mA should last in the
MFJ-259 when left on without turning off?

Thanks

They won't even charge in my Smart charger. They just shut down the
charging as if there no good, but they are supposed to be brand new. Just
borrowed some 1800mA and these are charging fine in the MFJ-259, so it
looks like the problem is with the batteries. I have never experienced
this with these type of batteries before only NiCad's.
=======================================
Suggest you allow a say 100 mA current to flow through the individual
(new)batteries , monitoring the voltage across the battery.
As soon as the voltage is 1.2 V you can further charge in your automatic
charger.
When fully charged , discharge either in your automatic charger or
manually (with a 12 to 15 Ohms resistor) ,down to
1Volt and recharge. The (new) batteries should then work well.

New NiMH batteries often need a few manually imposed charging
/discharging cycles before working properly.

Good Luck
