ATV Battery Trickle Charger

Recommended Posts

If the batteries have been discharged to that point  they are scrap.

Even  if you could trick them into taking a charge ( the old ferro/mechanical  chargers would charge those batteries)  they will  never have any decent capacity , and in fact  are very likely to develop  shorted cells  due to the  plates shedding  sulphates.

gotcha yea i was afraid of that tho i have heard that some nicer batteries will come back from the dead so i wanted to give it a shot and maybe save some $$$ (these are like the big diesel batteries two are for a tractor the other is for a bulldozer.  not sure what new batteries will run but im sure it wont be cheap.

do yall think the viking charger listed preveously will handle a bigger battery for a diesel motor with high cca or should i get something beafier? and yes i agree with @davefrombcthat once batteries drain and sit drained for a while they go to crap but i still wnated to give them a shot and if not that at least have something to use later on for big or small batteries

Huge batteries like those ones should be charged with a 10  amp or larger charger. Trickle chargers are only good for keeping one already fully charged topped up, and even then some require the larger trickle chargers because of internal leakage not  noticeable on smaller batteries. 

You can "shock"  those big batteries into  taking a charge sometimes by  hitting them  with 24  or more volts DC. Connect two  12v batteries  in series and then connecting to the  terminals on the big dead one for a few seconds. It  may knock a little sulphate off the cells and allow them to show enough voltage  your trickle  charger or bigger electronic charger will start up  on it . Only  hit the dead battery for a few seconds at a time and be sure to  be where any acid  that might boil  out won't hurt anything..especially you. The best way to try to  get  them to  take a charge though is with one of the old chargers that were basically  just a transformer and rectifier. They don't sense the battery voltage,  They just supply a constant voltage  that at first will show nearly  no  charge rate until  the battery  has gained a little voltage back. As battery voltage rises the charge increases but when it is near the  charge output voltage the rate drops again.  Those old  chargers don't shut off when the battery reaches full  charged voltage . They will keep  pumping current into the battery  until  it boils out or shorts.

It's worth a try if you have the batteries there .. You  may get lucky.  Otherwise hopefully  you have a recycler there that will  pay you for their lead content. I took  about a half dozen  dead batteries of various sizes to a recycler here  and walked out with  over  $100 in  my pocket

No issues with the Harbor Freight float charger.  Been using it several years.

I use an older (2015) Noco battery charger that works on 6 or 12v, and has modes for different setups, including a maintain mode. To make it more likely that I'll plug the quad or whatever else in, I have these installed these quick connects on leads to the front grill guard, I have them on other vehicles as well is in the bed of my truck so I could actually charge/jump the quad when it's in the truck: https://www.amazon.com/OrionMotorTech-Battery-Connect-Disconnect-Recovery/dp/B014FEV6EU/ref=sr_1_8?dchild=1&keywords=battery+fast+connect&qid=1610029637&s=automotive&sr=1-8

More expensive, but more uses and I don't need it there 100% of the time.

      Replaced battery, relay and starter. Turns over and starts part of the time and other times just rapid clicking.

      Hello everyone,
      My Suzuki LT185 didn't come with a battery from the factory (no electric start). I was wondering if I would need to add a battery if I wanted to install some of those light bars/pods or should I just wire it in to the headlight switch? Will the generator be able to put out enough juice to run the light bar? Also, is it normal for the headlight to get dim at idle, then brighter when driving? Never had a quad before with just a generator.

      Hey yo quadsters, I have a question regarding CCA in batteries. My ATV is cold natured and it will start with my generic battery that's in it, (don't ask me now what battery I have in it cuz I'm at work,) but when I hook up an external battery storage unit (Beatit 1200Amps QDSP 1200A Peak 16500mAh 12V Portable Car Lithium Jump Starter) for quick jumps it fires so much faster.  Which by the way is a bad ass accessory to have around. I keep the battery in the quad fully charged all the time. My question to the pros is how much difference does the CCA of a battery contribute to the quicker start?

      Installed new battery was told that’s what was wrong when hit start button I hear 1 click then nothing?  Can the battery just not have enough amps to crank the starter the first time ? I trickle charged it overnight thought it was enough!

      Got a 04 Sportsman 500 that wasnt running- owner said it needed a stater and a new battery.  It ran rough (been sitting out in the weather for a while).  A friend and I started by adding a new battery and it would start barely with the choke and his hand over the air-filter.  I decided to install the new battery in the holder on the side.  we had it on the rack because the old on was still in the bike.  I tried to be nifty by turning the battery to put the terminals in an easier spot to get to, but forgot to reverse the cables too.  In a sentence, I reversed the positive and negative on the battery like a dummy.  When we discovered my mistake and corrected it, we turned on the bike, but the display did not light up and the key did not turn on the starter.  jumping the solenoid worked the starter, so we thought the solenoid just burned up when I reversed the pos and neg...  new solenoid and no difference.  what have I burned up?  Also, the shifter does not seem to do anything in the trans.  it slides back and forth like its stripped in the trans.  any help would be appreciated!!
      I think the biggest issue right now is the electrical.

      Hello everyone,
      Im new here, this is my first post and Im trying to figure out how evrything works on this site so I please let me know if Im doing anything wrong.
      I have a couple Yamaha's but this post is in regards to my 02 Grizzly 660, I have an electrical draw somewhere that is taking my new battery down rather quickly. I have tried to locate any short by checking each circuit but was not able to locate it that way. Im installing a battery cut off switch which brings me to my first question, dont these switches usually go on the Negative terminal?
      My next question is, can anyone tell me if this year and model has any history of electrical shorts that might help me locate the culprit? Any help would be greatly appreciated!
      Finally, Im looking forward to being a member of this site and hopefully helping others as well as learning some things myself, so greetings to all!
      Best wishes to everyone!

      Hello i have a linhai 300 of the 2004+- era. I had a cluch problem so we changed it. After changing it has a hard time to start going. When you pop it into gear and press the gas it barely drives but when it starts going about 20km/h it start driving well the acceleration is normal and everything do you have any idea of what could be the problem

      picked up my third timberwolf 250 for my daughters.  these are great light weight little quads.
      have a strange one for you.  the quad will NOT start in neutral.  it will start in first. 
      if i lift up on the gear selector just enough to hear the little click (its not loud, sounds like a contact clicking, perhaps the neutral safety switch?) the light will go out, but it won't yet be in first either.  that is how i have shown my daughter to start it and she can.
      id like to carry out whatever repair is needed.  i have the pdf of the shop manual but it doesn't really have a flow through diagram.
      any help appreciated!  thank you.
      i need to add something.  it feels like i can switch into another gear BELOW neutral.  
      so if i switch to neutral, i can keep pushing the gear selector, and it has another click below the neutral.  the light stays on, and when i pull up into first it kind of feels like it has two positions it moves through to arrive at first.

      fighting this thing for a month now.No spark at plug.
      New ignition coil,pick up coil,stator,reg/rectifier,all new wiring.Started it up today rode for an hour shut it off.Tried to start later wont start.pulled plug wire it firing a blue spark while starter button is pressed.Tried new plug no change. It stared a couple times an ran for few seconds then died.Will CDI act this way? The reg/rectifier get pretty hot is this normal?
