FLOAT CHARGERS

Post by ViragoJoe » Sat Oct 10, 2015 9:12 am

Float Chargers and how they work.
From what I have read, some Battery Tenders do not shut off and can over charger your battery, especially when stored over the long winter months. So, basically, the choice is yours on what you use. However, here is some information on Float Chargers:

Harbor Freight sells a nice inexpensive Float Charger. At times on sale for $4.99.

Battery Butler is another Float Charger:

Joe - where did you read that Battery Tenders overcharge / don't shut off? I've used them for many years with no apparent problems.

Been awhile Dave since I read that. To come up with the exact read would be difficult.
Just that that is what it stated. Trickle vs some Tenders vs Float chargers. There has to be a difference between them or they wouldn't make them all. Just passing along what I've read. So far, we can still make choices. So you make(s) your choice and you go with it. Chargers are like oil. We can beat it to death until the cows come home. Provided they have a GPS. And now, which GPS to buy! LOL :lol:

7/24/16 Dave, Deltran Battery Tender is basically a float charger:
Just a tad more dollar wise than Harbor Freights $5.00 float charger.

Joe,
I'm with Dave on this one. I have 6 Battery Tenders and they all float/maintain properly. My buddy that owns and operates Macomb Battery warned me about the Harbor Freight "floaters" as he has seen too many of them that simply don't work. But then they only cost $5 so I guess you can buy several if needed. That's my Harbor Freight Philosophy.

Yup, I hear you. Never had a problem with the Harbor Freight $5.00 unit. I don't think they were intended for commercial applications as in your friends battery shop (just saying).

Been using the same one for 8 years. We are free to make choices on what we purchase. I am only providing alternatives to what is available (with a cost savings). How they operate is provided from sources from the internet. Information herein is to help folks be aware that there are indeed differences and to research prior to making a purchase (most don't care how it works. They just plug it in not knowing the consequences). You and Dave happened to find units (tenders) that turn on/off similar to float chargers. Not all tenders do, according to internet sources. http://www.ehow.com/facts_7646389_diffe ... arger.html

As you and I have discussed on another occasion. The amperage rate that a battery should be charged is 10% percent of the batteries amp hour rating.
A 21 amp hour rated battery at 10% charge rate should be no more than 2.1 amps for a motorcycle battery. 21X10%=2.1 http://www.dansmc.com/batteries.htm
There are other sources out on the net that confirms Dan's advice.

A battery with a less amp hour rating may not be able to handle the 2.0+ amp feeding. Another reason why, I went with the Harbor Freight unit. The charging rate on mine is 600ma or .6 amps. When charging motorcycle batteries, low is the way to go, again, from what I've read. I don't make claim of being an electronics engineer. Just providing information I've read.

Believe your tenders were 2.0 amp rated. Tricky to use on less amp hour rated batteries and may need to be watched when charging. 14 Amp Hour battery 14X10%=1.4 Amps maximum suggested to charge it as per the 10% rule. Using to much amperage causes heat which can deform the lead plates within the battery, risk of melting the plastic case. Requiring the need to keep checking the battery case to see if it is getting HOT. Increases the hydrogen gas pressure internally. The evaporation rate of the electrolyte is increased in non sealed batteries. As Dan says in his article (para phrasing here) "it's OK, I don't care, its not my battery!"

As Yoda would say "do, or not do, yes!! However, too much amperage can put you battery on the dark side of the force.

The attached video is to show the results of charging a motorcycle battery with higher amps:
https://www.youtube.com/watch?v=lJty14qwJtE

The battery tender junior, if I read the packaging correctly is 750ma(s). That is the one, I would use and stay away from the 2.0 bench top charger. But, that's me!

To those who read this. Information provided here is to assist you in making a decision on what you purchase. No product endorsement intended. The choice is yours to make and yours alone, then go for it. Just sharing what I know through researching. I suggest that you do the same - research will set you free. Or confuse the hell out of you!

Nice research Joe! To each his own but the lower milliamp tender/floater does make sense especially if hooked up all winter. :ugeek:
