Subject: Battery maintainer


Plainview, mn
I was having weak battery issues on a 2007 case loader tractor. The battery is only 14 months old and granted its been cold i figured i shouldn't need a new battery yet. I only feed or load hay every few days but i was needing to put booster on to get it started and barely got it going a few times. Its plugged in too. So i went and bought a 2 amp maintainer for $25 and put that on on between uses. Works like a charm. Thought maybe i could help some of you too

Just started using a battery maintainer last winter. Now I have three of them all different brands. Move them to different equipment throughout the winter. Love them.

Sounds like you have a battery or charging problem. The maintainer might just be masking the real problem. I like maintainers but in your case it shouldn't be needed.

Same here-finally just bought several cheapies so can keep about 1/2 stuff topped at any time-then rotate every few weeks.

Depends on how long you run the engine after starting.  Starting takes a lot of "juice" and it takes a little while to replace it.

You are correct, that may be the issue.  But if he has had the same loader for more then a year, and the duration of feeding hasn't changed, and all the sudden this year its a problem something isn't right.  I would load test the battery to make sure it's good, just as well get it replaced now while it has more warranty.

Not really. If for example an engine cranks and starts within 3 seconds, and during that time the starter drew 500 amps, then the total energy consumed would be (what I'll call) 1500 amp/seconds. If the average alternator puts out 100 amps, it should be able to replenish that loss within 15 seconds.

Looking at it another way, put an amp clamp around an alternator output wire sometime and watch the alternator output immediately after starting an engine. You'll see the output quickly shoot up to max rating, but only for a few seconds, after which it tapers down quite quickly.

I get what a couple of you say. Only firing tractor to load hay once a week and feed once a week, sometimes on the same day and sometimes on different days. Tractor was sitting in open shed. Maybe its masking a problem, maybe not. All i know is works great and i didnt need to buy a battery yet.
