I am Charging two new Group 29 marine deep cycle batteries with the XC103W. When tested with a voltmeter, it was consistently reading typically about 13-14v during maintain mode, but now, during maintain mode, the voltmeter reads between 15.5 and 16v...

try charging one at a time see if that helps..make sure fan is running..or try a different setting...other than that i dont know

Yes- even is says 6 or 12 Volts- it will still check a 8 volt put the Red on the + side and the Black on the _ side and read the volts should read 7 or better --Then hold the load switch and it should read between 12 and 6 volt if is not a bad battery-Some of the old car restorers use 8 volt Batteries in what used to call for 6 Volt to make them turn over faster

1.5 volts I checked them with a multimeter and they checked out.The first three seemed to drain quickly, but the next three are still going. Can't beat it for the price.

The operation voltage of NiMH batteries is just 1.25V. When freshly charged, the terminal voltage may reach 1.4V or even slightly higher. Depending on the charging current and battery temperature, you may even see battery voltage reaching 1.5V. But this voltage will decay below 1.4V if you let the battery rest for a few hours. Bottom line is: your charger is working perfectly fine.

A meter that will read DC volts is the only accurate way.Read between the black and red on the lead that plugs into the plane,as this is where the output voltage is.This is a 3 cell battery,consisting of 3 3.7v cells,which together equal 11.1 volts.If a cell is bad,you may get a lesser reading of 7.4 volts.

I had the same problem. So, I tested the battery with a multi meter and it tested at 4 volts dc. That was the condition it arrived to me in. I tossed it in the trash and bought an equivalent from RADIO SHACK. It tested at 12.3 dc volts. I hope this helps.

dont know but its very little.i hooked mine up to my deep cycle battery overnight with my digital meter also hooked up and didnt drop any volts, not even a tenth of a volt.

I do not know why in the product information it states 20v but I have had this unit for 6 months now using my 18 volt porter-cable batteries ....it works great

All 4 of my chargers are set for 4.2v.I have had NO problems at that setting But, always charge new batteries as soon as you get them.I charge all my batteries, any size in it.The charger is automatic , stops charging at the correct voltage.George

Several possibilities for the problem. Use quality batteries such as Duricell and be sure to buy from a supplier with a high turn-over. Be very sure that the battery's are fresh. Even a dead battery will measure 1.5 volts but it will not be able to deliver the required current. When operating with low voltage, contact resistance is always a problem. To minimize this resistance issue, always spin the battery's after installation, this polishes the contacts. There is always the possibility that the unit is defective. I have not had any problems with my unit..............hope this helps.............Bill

Honestly I don't know. I don't do much boating, but if the connectors are similar to that of a car battery then there's nothing stopping it from working. One thing I do know is that if it's a sealed lead acid battery do NOT charge it when the voltage gets near 11vt. It'll ruin the battery. As far as the equipment is concerned, I must admit there was something wrong with the packing and they sent me the wrong stuff. I bought a different charge controller called the 'cyclopse' and it worked fine.

I have never noticed the 4.5 volts written on the inside, but mine say that too. I have 4 talkabout radios and the batteries are all 3.6VDC, and they work perfectly.

It is rated at 350A continuous so I think you should be fine. I can't remember but maybe rated at 1000A for short period (starting) I installed it in my boat to separate 2 800 CCA batteries or so both could be used to start if necessary. No problems at all. Not even a little warm. Not sure about the voltage though.

Fresh off the charger these batteries will read 4.2 volts, and drop down to 3.6 where they last for a few days for me, and then go to 3.4 when I put them back on the charger

Same problem with aircraft batteries. I tried setting it at a low CCA battery setting to see what would happen and got a reading. I have no way to know if that result is accurate. The thing is designed around inputting the CCA to do the test, so I guess it might not be the answer for you. You might want to consider a carbon pile style tester.

Reading the spec sheet for the LM2577, looks like the quiescent current is about 10 mA. The actual input current when under any kind of load, of course, will depend upon the output power. For example, if you're using 5v in and getting 10v out, the duty cycle current on the 5v source would be a little over twice the amount you're drawing out at 10v. If you're using a standard USB connection as your source, in this example you'd be limited to about 200 mA on the output side.

these batteries are 1.2 volts. i looked at one of my batteries to be sure. they are aa/hr6/dx1500nimh 1.2 v/200 mah and that is on the battery and easy to read !!!!!!!!!!!!hope this helps, charles davis
