Default MFJ-259Z

After charging and discharging over the past few days they are finally
keeping there charge. I have had the MFJ-259Z switched on with the power
save turned off for the past 10 hours and still have 12.6V left in the
batteries. A big difference from the 10-15 minutes I was getting from them
when I purchased it. All I have to do now is to learn and then test the unit
to make sure it is working ok. As I am new to using a Analyzer.

Many thanks all for your help.

For what it'sworth, I looked at an MFJ-269 manual, and it claims to
trickle charge at 10 - 20 ma. At that rate it will take a long time to
charge a 2600 maH battery. They say minimum Vbat is 11V, but mine gets
flakey below 12. You might want to measure the under load battery voltage
when it fails and when you think it is fully charged.

I don't think a 2600 mAh cell will ever become anywhere near fully charged
at that charge rate. That's barely enough to maintain an existing charge.
