Cheap Trickle Charger for Tractor?

Greetings, yard warriors. Not using the Wheel Horse as much with the grass growth slowing down. Any of you guys have a fav trickle charger of one amp or so that won't break down in a week? Thank you. Enjoy the 2019 NHL Hockey season.

Re: Cheap Trickle Charger for Tractor?

I believe it's an old Schumacher that I have. Select between 1 and 4 amps. Got at garage sale for $1. Same deal on another one I have, maybe 2 amp, selectable between 6 & 12 volt.


Overkill.
I love overkill.

Re: Cheap Trickle Charger for Tractor?

I've used a few of the AC to DC adapters that are 12V DC output for various household appliances to keep a battery fully charged--ones with at least a 1 amp output..and be SURE it is DC output,many are not!..

They do not have a self tapering charge like most real battery chargers though,they can over charge,you must take them off every few days..

I've seen guys use an old computer power supply and RV ac to DC adapters to charge batteries too..

I have at least 5 battery chargers,one is a 1 amp 6-12V trickle charger for motorcycles and tractor batteries,,found it at the flea market for $2..
I think its a shumacher..probably 30+ years old...

Another one is a Sears one my dad bought around 1978,it is a 6 amp but has another mode you can use and dial in anywhere from .5 to 1-1/2 amps for small tractor and cycle batteries...still works good,and its seen many hours of use..

I bought two 10 amp old school Schumacher chargers for $3 each at the flea market,both identical,and they still work ok...there's always a lot of them there for sale and yard sales ,people practically give them away when cleaning out a garage or a deceased mechanically inclined person's collection..

My friend gave me two of his old chargers from his shop that were old and the big one was pretty beat up-it is a wheeled version with several amp settings and a 225 amp starter boost--unfortunately it wont put out any voltage,everything looks fine inside it ,I guess the diodes are shot,and though they still list part numbers,they are "NLA"...hate to scrap it for copper,but its of no use if it wont work..one site online I found said some alternator diodes worked to fix his,but I'm probably not going to bother fiddling with it..

The other one is a nearly new "smart" charger that looks brand new,inside & out,but its "dead"...probably something to do with the printed circuit board with IC chips and a lot of other electrical things like resistors and capacitors..
I'd never buy a new "smart" charger,they are pretty much junk IMO..useless for an electrolosis tank too..

Re: Cheap Trickle Charger for Tractor?

I hope you have better luck that I did.. I bought 3 NAPA brand fully automatic w/auto shut off 2 amp - 10amp deep cycle charger/maintainer @ over $70.00/pop to keep the batteries charged on our boat over the winter. All 3 batteries were fully charged before I set the units to 2 amps and watched the little lights periodically going from amber (charging) to green (charged) throughout the winter. Spring came and I had 2 group 27 batteries that were toast from being boiled bone dry, luckily the starting battery was still good. From then on I just put a charger on them every few weeks during the winter; good luck.
I would like to find 3 battery tenders on the cheap for my old 4 Runner & both Cub's batteries but am leery so keep us posted.

I have this one-

It doesn't charge extremely fast but it will charge from dead eventually, and it does a great job of keeping a battery fully charged. I put my truck's battery on it for the winter.

Battery tender or battery tender jr, been using them for a number of years when my snowmobiles go on life support for the summer and my motorcycle in the winter.
No complaints or issues.

Same here: I use this one. Has a red and green light It does not charge fast. It's a trickle charger just to eventually get and keep a battery charged.

I had some that eventually boil a battery dry and were suppose to be trickle chargers.

Re: Cheap Trickle Charger for Tractor?

Battery Tender brand is what I use. I use a regular one in my garage to keep the two garden tractor batteries charged during the winter, plus the battery that I pull out of the big Ford tractor and put in the garage for the winter. I rotate the charger from one to the next every couple of weeks, and my batteries generally last 7 to 10 years that way. I also have a battery tender junior that I keep on the generator battery year round. Only been through one generator battery so far since I got it, and that one lasted about 8 years.

Re: Cheap Trickle Charger for Tractor?

You can always put a timer on the circuit/outlet to keep the charger from running 24/7.

Re: Cheap Trickle Charger for Tractor?

One more opinion: I just put the charger on every few weeks like others have said. But, If I were to go the constant or over winter route, I'd spend the bucks on a marine charge maintainer. NOCO and Schumacher are pretty highly rated, but they start at about $70 bucks and go upwards to close to $200. BUT these are heavy duty and are not supposed to boil the battery dry or burn your shed down, or at least so they say.

I think I'm going to stick with just recharging every few weeks. Seems to work for me.

Good luck.

Reference to post #8. I kept trying to edit and correct the long empty space with no image but could not even delete the long empty space nor the post. Maybe it was a copy of the empty space in my Brain.

Anyway:

You can find the Battery tender jr with a search. I use the little battery tender jr on RV's and standby batteries that I need the bat ready to go.

I've got several different type of Battery chargers, so called Automatic and others. I've tried the unhook then re-connect later which is no good, you will forget to do such, I've tried timers, solar cell chargers when on sale from Northern tool with some success on eq that has no grid voltage close. I've got some automotive sealed trickle type automotive expensive types ($60-80 when new) permanently mounted under the hood of vintage auto's that work ok that I picked up at garage sales for just a few bucks or from salvage yard vec's.

Not a fun thing when you find a expensive battery boiled dry, but sometimes it's not the chargers fault. If a battery gets a shorted cell the bat's voltage will go low and the charger will see such and just keep on trying to charge up the voltage and then you find a boiled bat and blame it on the charger. (this situation can also be very explosive dangerous if a spark happens due to Hydrogen buildup from a boiling bat)
