harbor freight battery charger


The problem is that the device will grossly overcharge a battery over time. The strong cells boil and the weak cells continue to charge. This is a battery tender. I essentially gutted it and replaced most of the circuitry with something incredibly simple, and it has been very reliable so far. Harbor Freight also sells an 8 channel connector so you can hook up multiple units. Cen-Tech.

Nothing but two leads sticking up through the board. Sounds like these devices are going downhill even worse than they used to be. I did not think that I needed to check it. Theoretically the charge controller should already have blocking diodes on the solar panel side, otherwise it will give all back the solar power at night.

Reply It would be fun to take apart one of the ones that failed to see what actually happened. There's a problem loading this menu right now.
Purchased two of these for new Honda ATV's I bought for the kids...2 weeks after install noticed the battery was leaking acid on one of the ATV's.. 20v Hypermax™ Lithium-Ion Cordless 1/2 in. Also, variable resistors can be bumped and change value; an important consideration in something that will be tossed around a garage by people like me. I don't know this for sure since I haven't open the device to see the design. Oh well, I have a few (hundred) diodes laying around that can do this job for me. I guess I got lucky, I checked the voltage and its right at 13.37 output. I assume that this is a PWM type but I don't really know. I also leave the battery outdoor in case of outgassing. Add to Cart Add to My List. There are many different kinds of controllers and they all work differently. Is it better or worse? If I had the time and space to set up my test bench I would open up the box and adjust to 13.5 volts dc for charging my batteries.

I have the block that u put 8 panels on also but im only getting 15.4 volts outta all this and i have to unhook the box at night because i dont have the diodes on mine yet. 2/10/40/200A 6/12v Automatic Battery Charger with Engine Jump Start $ 149 99. Drill/Driver Kit with 1.5 Ah Battery, Rapid Charger, and Bag $ 64 99. bar and 42cc + Show More. My guess is that many are trying to charge a bad battery. If you do use a diode, make sure it has enough current rating (and that it's placed so it's OK to get hot). I added a diode and trimpot to mine (which also had a bad LM7805). This is a journal of my various efforts to bring this problem under control using the cheapest technology I could find.

I would suggest that, if you setup the system correctly and find it does discharge (the battery) when the Sun goes down, the unit is defective. 42cc 18 in.

The 7805 is a tough little chip with over current and temperature protection. The battery diedand the charger was 10 volts. So, I hooked one of them up to an AGM battery I have in my car and let it work for a few days.

In my case, I salvaged some old 12V SLA batteries by refiling with Epsom water. 5 years ago Especially when it's going to be left hooked to the battery for months at a time (all winter).Take a look at my post of March 2, 2012 for what is likely to be my final solution. Do not use on gel lead-acid or AGM (Absorbed Glass Mat) type batteries" * on page 2 of the instruction manual Intended Applications "For use on fully charged lead-acid and AGM (Absorbed Glass Mat) type batteries only."

There's a battery minder out there made by Yuasa that does something similar. The answer was obvious when I checked the prices of the various components; fixed resistors cost a fraction of a cent in quantity, variable resistors are much more expensive.

The reason for the 'fully charged' comment is that the power supply is so small that the thing can actually blow the protective circuitry in the wall wart and kill it.
