Does it keep a steady output, or does the output fluctuate according to input (i.e. as battery level changes)?

In my application, running inside a car, the output is solid when the input changes (12V with alternator off & 14V with alternator on). So the output stays the same when the input chages.

It will keep a steady output as long as the voltage and current on the input is above the minimum. As long as the input voltage is 1.5V above what the output is, it will stay steady.

My charger's light blinks until the battery is at full charge then it turns steady. Hope this helps you.

it will retain memory when changing batteries. you have to turn off then change. i use recharge batteries and never have memory lost.

If you mean does it give you the level of the battery use....NO. But it works fine. Just keep an additional charged battery with you.

Yes it will maintain you batteries, I assume your batteries are wired parallel. For reference .... it takes a good sunny day to recharge a battery that is one fourth discharged or in your case with two .. probably two sunny days.

I usually keep it charged when using it, so I'm not sure if it does or not.

I use mine with the battery so it does it lose it's setting. We have a couple of power outage and so far, the unit stay as programmed.

As JZ said; the voltage shouldn't vary once it's set but I recommend checking it under load just to be sure.

My indicator does the same , but stops once I start moving forward. ( not sure why ) . My indicator does not give me a true reading to the battery charge . The lights run from green to red , red being that you require a charge . On mine I get the level down by three to four lights ( never reaches the red and I need to charge her up. ( and the batterys are brand new ) !

It doesn't. Stays on but can adjust the intensity. Battery life is projected at 6 years. Mine had been on 2 years with no loss of intensity.

The output voltage is constant from power up. Constant at the voltage you set it at.

Yes, it does. It appears to hold the high/low setting also. I have turned it off and back on and also had a blip with the electricity and the frequency stays to what I have set.

This is just a guess, but the device is digital. It is possibly not fully charged and so goes to the highest level it can maintain. As its power drains below what's needed for the highest level, it drops a level. If it is fully charged, it might be defective -- ours stays on for extended periods.

I have been using regularly so have not seen any degradation. Battery has a really nice built in monitor. Just push button and it shows from 1 to 4 amount of charge. I have found this to be accurate on use and remaining charge. Other lithium-ion tools I have show very little degradation over time.

Yes, it automatically switches from main power to backup. I have the generator wired to main and batteries as the secondary source. When I shut off the generator, it switches to batt right away. When I fire up the generator, there is a 30 second delay built in so power can stabilize before switching over. Had it about a year and has worked flawlessly.

it does retain its memory for 'learned functions' for battery change outs. as for long term without batteries, I don't know.

Yes, it keeps a running total of the number of times it goes off until you reset it.
