I use a power supply for charging in all my battery test, but it is computer controlled. This means I can simulate charging algorithms correctly.
For CC/CV it works nicely without computer control, as long as you disconnect when the current is low.
For -dv/dt or NiMH/NiCD it do not really work.
Why do you use 4.1V, do you want to get longer lifetime from your batteries?
I checked out your site. Wow, good job!
I have a related question, I tried recharging some Energizer alkaline AA batteries a few years back, and some recharged great, and some didn’t recharge at all. Do you have any experience with this?
I use the DPS5020 power supply to charge li-ions on a regular basis but I never leave it unattended or for very long after the charging current has become low.
I think Texas_Ace uses his for this purpose alot too. I have never had a problem charging, checks out to be pretty accurate and follows the proper CV/CC algorithm as HKJ pointed out. Works great for me.
