Trickle Battery Charger
What I want is a low amp battery charger that will cut itself off completely when the battery becomes fully charged. This will be sort of a "maintainer".
I tried a Schumacher 6/12 volt charger that used vague language to suggest that it would do the above. I tried it on 2 different batteries and it never shut off. It appeared to be over-charging the batteries, so I returned it to the seller. Is there any "maintainer" charger that really completely stops the charging when the battery becomes fully charged? |

Re: Trickle Battery Charger
I would prefer to plug any low amp charger into a timer.

Re: Trickle Battery Charger
Sears sells a 12/6 V auto select low current charger ~2A I believe... that does just that.... I got mine for ~ $25... Works well on my 6V battery and got my Mrs. 12V back in shape after the lights were left on...

Re: Trickle Battery Charger
I am very leery of any charger that says,automatic,floater,maintainer,or smart charger.One little tickle from a thunderstorm and the sensitive parts seem to become solid circuits.Anything that has little lights to tell state of charge make me nervous.Same thing with chargers that say they will shut off when battery is fully charged.They may do it when new,but once they've been dropped they seem to just keep charging.I've had two real serious problems with the Deltran maintainers.The company got back to me a few months after I contacted them,they said if somebody tries to start the car with the maintainer still hooked up the sensors could get fried.One had a meltdown sitting on the top of a Wheelhorse tractor,the other one I had hooked up to four batteries in a Brockway.Batteries were in parelell,and I left the maintainer hooked up to them for a week.I walked into the shop one morning and there were pieces of battery all over the place.Turns out the thing never shut off like it was supposed to.Is there a reason you feel you need a maintainer? If you have a drain,you have something that needs to be fixed.

Re: Trickle Battery Charger
I have used Battery Tenders - 6 and 12 V models - for years without a single complaint. They cannot overcharge.

Re: Trickle Battery Charger
I have used a "Battery Tender" for 8 years.
7 years was with the same battery. Replaced the battery because I thought I was pushing my luck, but the battery still worked fine. When I was not driving or working on it, I had the battery tender hooked up. http://www.amazon.com/Battery-Tender...ry+tender+plus

Re: Trickle Battery Charger
I have trickle chargers on all of my collector cars and bikes. I went that route after I had to buy 3 brand new Harley-Davidson batteries in only 2 years because I didn't use the damn bike. Since then I actually use the cheapest and lowest power motorcycle chargers, even on my Model A. It charges only 0.5 amps per hour, which is fine for what it's needed.

I also have one of these Sears Die-Hard chargers and they have some excellent features. It has no on\off switch, but it will not automatically turn on until it is connected to and sees a battery. If a lead should fall off it shuts off. When the battery is fully charged it shuts off. Works on both 6 and 12 volt batteries. Switch to 6-volts and it charges at 4 amps, switch it to 12 volts and it charges at 2 amps. Comes with battery clamp cables and a cable with a device you can plug into the power outlet (cigarette lighter type) on a modern car. Tom Endy |

Now, I just hook it up every month or so until it transitions from charge to trickle (the led turns from red to green), indicating that the battery is fully charged. |

Re: Trickle Battery Charger
I have 6 and 12 volt Battery Tender's and a 6/12 volt Black and Decker that I bought at Home Depot for a really low price. They all work well and will charge up a low battery if you are willing to wait for a couple of days.

Re: Trickle Battery Charger
I too have used a "Battery Tender" for years.
As mentioned you can also place a regular charger on a house light timer.

Re: Trickle Battery Charger
My Montgomery Ward 12/6 volt 8 amp charger has a manual timer on it which also works as an on/off switch. Twist the knob to the number of hours you think necessary and it shuts off by itself! Also has an analog meter to show how many amps the battery is willing to take! Bought it for five bucks at a garage sale!

Re: Trickle Battery Charger
Power Tender here too. Used for many years no problems. 1.25 amps
Probably not a bad idea to use a timer I'll give that some thought. Also, like to have the batteries out of the vehicle sitting across the garage on a shelf. |
