Once the battery type is selected, does it "remember" or do you have to set it each time the charger is turned on?

Once it's set, you're good to go. I installed mine well over a year ago. After unplugging to go out on the lake, I just replug it in when I return and it "remembers" the setting. I haven't had to replace a battery in two years.

Good Question: The only time that you have to re-enter the battery type is when there is no power applied to the charger (either battery, or the 110Volt wall plug) So if it has either type of power applied it remembers.
1297911
it remembers until you unhook the batteries or when the batteries completely lose charge
1297912
No, it will remember. Mine actually knew what battery type I was charging once I hooked up the batteries (2 - 12v).

i believe the charger turns off automaticly after the battery is charged at least some do tho some chargers tell you that you are useing unnecesary electricity by leaving it on but i would suggest removeing the battery once it is charged.

Yes it does. However, you need to tell the radio what mAh capacity batteries you've installed. With the radio off press "System Set", then "28", turn the tuning dial to the mAh of the batteries, then "System Set" again. Now you're ready to charge. BTW - this only needs to be done once as long as you keep the same batteries installed or replace with the same mAh capacity.

.Direction say to leave it on the charger all the time except for when you're using it so it will be charged whenever you need it

acording to the instructions, it goes into a "maintenance" mode after the battery is fully charged, which can be left connected indefinately. I have not personally tested that feature. I have not been able to bring back a "failed" battery with this charger or it's close competitor, as tested on several batteries. It does seem to extend the life of a near failure battery, but only experienced on one so far.

Yes, it does prevent over-charging. This is accomplished by the charger switching to a type of stand-by mode when the battery is fully charged. Its LED display shows the specific cycle in which the charger is operating. If the battery power drops to a level below full charge, the charger switches to charging mode to top-off the battery again. I am completely sold on this CTEK Charger! Also, it CAN re-charge a supposedly "Dead" battery, if the battery is still capable of accepting a charge. This is achieved through its "de-sulfation" (altho this is not the correct term) process.

I assume you mean how does it monitor the battery and then charge as needed? It can't overcharge, so you place it and forget it.

No, it just stays red to indicate the charger is connected and working properly. I just charged mine for 24 hours initially and overnight since then to recharge. They recommend you never let the battery fully discharge.

Mine has always been turns red to charge and changes to blue when ready to use.

Yes, on the battery itself. You just press the button and one to three green lights indicate the charge. I always charge it after use as they recommend, so it is charged up for the next time.

It has been a while since installed it but it uses a mall backup battery which I did test. I forget how that I tested it.

I leave mine on a charger at all times and it doesn't appear to damage or effect performance. perhaps there is some battery expert out there who can offer a more educated response.

Yes, the old-fashioned way. Maintains a constant voltage, that causes the battery to automatically go trickle charge once it's charged

When you plug it in to charge, you must press the button to the right of the 25. Then the 25 will glow solid. This means it's charging your phone. Once your phone is 100% it will switch and charge the battery backup device (and the numbers will blink). Once the backup battery is done charging itself, it doesn't switch back to charging to phone. I think this is a design flaw. So if you don't press that button when you plug it in, it only charges the backup battery device.

NO, however, as stated in the manual; In the "Automatic Charging Mode" When an automatic charge is performed, the charger switches to the maintenance mode automatically after the battery is charged. Hope this helps you.

I believe so. According to the manual, "after 24 hours, the charger automatically turns off and a Green light is lit for each bank to indicate the battery is in long term Maintenance Mode and ready to use. The charger will automatically turn on when the battery voltage drops below 12.6V." If you are using batteries that are "water filled", make sure water covers the plates inside the battery. If not, you need to add distilled water to the batteries and make sure it just covers the plates inside. I would check the batteries on occasion to make sure they are not hot to the touch. I am very pleased with the MK 315D and keep it plugged in after every trip and only disconnect it when I go out again. I believe so.
