Would a battery really care about this, assuming its charging rate & voltage was adjusted to keep the battery within specs?

battery chargers typically have multiple stages or modes of charging which this power supply wont have.
Understood. The plan wasn't to use this for unattended, automated charging. My thought was simply that I could slowly dial up the voltage to recharge a small battery. Not planning to try recharging the ForkenSwift pack with it

regarding the diode, it will have to be a really really big one, batteries can take up to hundreds of amps (not sure what the power supply can supply)
It's rated at "3 Amp treadmill rating / 8 Amp breaker". I assume that's the AC side.

Note: you may not even need a diode.
Any easy, non-destructive way to determine this?

Thanks for the feedback!
