I keep my X series tractor in an insulated garage that has a heater. I just don't run the furnace 24/7. Since the tractor is not run regularily during the winter, only when I need to plow, does anyone have an opinion on putting a unit like a Battery Tender on the battery terminals? The BT is a trickle charger that cuts in and out to keep the battery at full charge.

Your opinions have been good so far, so let me know your thoughts.

Since the battery is usually fully charged when you shut down I recommend a very low amp charger ie for motorcycle batteries, 2/10 amp etc. I'm in an industrial situation with our own ambulance that is infrequently used. We had a 2 amp charger that was boiling the batteries dry. Finally put it on a timer limited to 4 hours per day at 2 amps. Ambulance has dual batteries.

Check out a battery maintainer. The best I have found is made by "Battery Tender". I use it on my all my motorcycles and it keeps them juiced up with no problems.

I use a Battery Tender on my motorcycle, I have a friend who uses 3 of them for his Corvette, John Deere B, and his motorcycle.
I would recomend then in a heartbeat!

The little HF trickle charger works fine and is under $8. It is voltage limited to avoid overcharging.

I plug it in when I expect the tractor to be idle a week or more.

I also have a 10/50 amp charger/starting helper for when this (or any) battery becomes weak, but the day I use it will be the day I buy a replacement battery.

As I understand it letting battery voltage fall below full charge, 12.85 volts, is what ages a battery. If you maintain full charge either by daily use or by a trickle charge, you are doing all you can and more expensive 'tenders' are not cost effective, at least for a $60 - $120 automotive type battery that is going to last about the same amount of time regardless of how you keep it charged.

What I did to maintain my battery when we went to Singapore for 6 months was to remove it from the vehicle and then connect it to a trickle charger through 2 of those 24 hour timers in series. I just set each timer for approximately 2 hours each.

When I returned, I disconnected the battery from the timers/charger and put it in the vehicle. Ran the glow plugs for the required time and then turned the key to "start". The engine started immediately, after about 1/2 turn of the engine crankshaft. The wonders of a diesel.

Don't use a regular trickle charger. Any battery can be overcharged by any charger other than an automatic. Overcharging will destroy any battery. Battery Tender will work fine. I've used and sold a number of them over the years. We've had a few fail, but over all the quality is ok and they do a good job of maintaining a battery.

I got a Battery MINDer based on an old TBN thread. It's like the Tender but is also advertised as a battery conditioner which is supposed to breakup the sulfation on the plates when it's in maintenance mode. It can be left on forever and can be hooked up to 4 batteries at once. I like it.
Cheers!

I'll second MikeD74T with the chargers. The Fire Dept I'm on has 2 ambulances that over time boil down the batteries. We have taken to putting the chargers on timers. I have never had issue with starting diesels in the winter. I have used block heaters and will be installing one on my 790. I'm also going to heat the barn that I park my tractor in seeing how it also doubles as my workshop and I almost have that finished except for adding some insulation.

Danbike,
I can relate to your situation. I keep my tractor, 1968 Mustang and my motorcycle in an insulated garage. Since the garage is attached to the house, the temp. never falls below @45 degrees. But, since these batteries don't get used much in the winter I have still had some problems. Last year I invested in a couple of Battery Tenders and they are great! I purchased them off of a motorcycle web-site called Motorcycle Accessories Warehouse . The Battery Tender Plus was @ $35, I use it on the Mustang and the tractor. The Battery Tender Junior was @ $21, I use it on the motorcycle. Before winter I top off the water level with distilled water, plug in the Tender and it does the rest. You might try another web-site too, it is Competition Accessories . They are from Ohio, and their prices are about the same. Both places are the cheepest I found, even better than e-bay. /forums/images/graemlins/cool.gif
