Ive charged a battery with a yuasa charger but it can't handle a "load test" could this possibly correct that inability to handle a load?

Do not know Yuasa charger at all. Take battery to a place where the battery and a test on its load can be done. Batteries do give up. Happy holidays

If the battery is really low, the minder won't bring it back. Charge with a regular charger and then put the minder on it so it can desulfate it. If this doesn't work, your battery is gone.

This is NOT a load test device. Its Load indicator light will turn amber if the battery cannot maintain voltage. The Carbon Pile Load Tester by Cen-Tech, Item #91129 may be what you're looking for. It's about fifty dollars.

These units use a sealed lead acid battery that, if it sits uncharged for more thn a few weeks, will not accept a charge. If you open the unit up, you can test the battery to see if this the case

The "load" connection is for the purpose of connecting a "Load" of some kind (perhaps a light that you turn on at night or other such) where the controller will allow your "Load" to drain the battery down to ~11V, but then it "shuts off" the load to not drain the battery to the point that it's hard to get it to recharge. So that should help preserve the life of the battery, but that "load" can not exceed the 7 amp controller ability.

Hi Dan...I bought the charger to analyze some 14.4 volt batteries from an unknown source. Here's what I said in my review: "It handles the batteries OK but the chargers autopsy pronounced them unresponsive. The next challenge is to find a battery replacement. Hitachi makes one that appears to have the right electrical tabs but I have to see it in person before I'm sure it's the right one." It is a "universal" charger which means a number of batteries from 14 to 18 volts fit the slots. I don't know what batteries Harbor Freight use in their tools but I bet they are some of China's "best". Their web site was no help....

I'm not a battery expert, but you should really stick to the charging voltage and initial current they show on the battery. Overcurrent will certainly warm it up and it may leak or explode on you, or just shorten it's life.

On my unit the clicking is the overload breaker and the battery never charges. If I measure current it goes to 300mA then clicks, stop and starts again in a couple seconds.I found out that it is due to the winter! My charger worked fine in the summer, not this winter. I verified this by bringing the charger inside, warming it up and then it works! But only for some hours till it gets cold again. My recommendation... for this price, buy a different unit.

You can charge that if you can get it to work. I was not able to charge a single battery with mine. It keeps shutting off like it is overloading or something. Total junk. Buy something better. You get wht you pay for.

Sorry, I can't shed any light on the subject, Brian. After ordering the charger I discovered the problem was with my battery not the charger - I returned the charger I purchased through Amazon. My battery had run too low to be charged using any charger. I had to take it to a golf cart service store and they got it up and running for me. The charger I had was perfectly OK.

This is a battery maintainer, your batt. should be charged before you use this.

I used my Battery Tender brand charger (made for lead-acid types) to charge this battery when I first received it. Based on the indicator lights and the charged battery, it appeared that all worked well together.

Not sure, I would contact Battery Tender Company,I'm sure they could advise you.

There is a small surface charge when you receive the battery but you must fully charge it first or the LT will shut down until it charges enough.Assuming you already fully charged it,the problem might be the battery itself.We also had a defective charger that was causing a problem as well.Both batteries that we have ordered have worked perfectly.The LT should work even with a dead battery.If it does not,the charger is bad.Good luck.

I have never had my batteries give me a problem nor have they ever ran a charge down. I do however believe you can replace them but if you have another problem like you didn't do a full charge before you ever used them, then I believe that would cause the charger to max out with less of a charge and never do a full one.

Sorry, I returned the battery because I had to fill it with acid, not something I wanted to do!! Maybe that's why your battery is not charging!!

I have 2 chargers so it was definitely the battery, as it wouldn't charge on either charger although my other battery charged with no problem.

i like the charger i have. the Yuasa smart shot. it saved the battery in my porsche. it charges the battery in my motorcycle just fine, but also the cars. if the battery has been sitting drained for a long time, it is most likely donesy, however.

I bought this battery and it had a issue the first time I charged it . It didn't work good luck
