    Battery Options for 753 bobcat

    Just wondering what you guys are using. Ideally I'd love to find a gel-cell(like optimas) battery to put in it. I have 2 in my cummins and they work great. Mine don't seem to last long as my machine sits for long periods of time throughtout the year.

    Thanks,
    Ryan

    I don't have much experience with gel batteries. I wonder if they can better tollerate the bouncing and vibration that Bobcat's dish out compared to lead plate batteries. As far as your problem of you machine sitting for a long period of time, I don't see how there would be a big difference in the batteries. If you typical lead plate battery discharged over this long sitting period, it's seems a gel battery would as well. Maybe you have a current draw of milliamps from the ECU that discharges the battery. Try installing a battery disconnect switch near the battery so you can just disconnect it when not in use. I've also seen 12V solar chargers you can put on your machine that keeps the battery charged up. Just some options.

    Very good ideas. I was actually thinking of getting a disconnect put on. Thing is I think this battery has been on the way out for a while, I've had to charge it every few weeks to keep it going. Yesterday I fired it up to move it outta the garage, now it wont start so I can put it back in. I had a 12v 6amp charger hooked up all night, and tried boosting it to no avail.

    So I'm thinking I'm gonna need a new one, and I can imagine what a dealer would want. So I was thinking of getting a gel cell with a 6yr free replacement warrenty. Ive been running two of these in my cummins since 01 and have never had a problem. I know my cummins will also fire up on only 1 battery as well. Since the bobcat has a way smaller motor you'd have to think it would work??

    Sounds like a plan to me. Like I said, I just don't have any experience to offer on the gel batteries. If you've had good service from them, I think it's a good idea to try on your Bobcat. I can only speak about the lead batteries. If you want high CCA, I'd see if I could fit a group 31 battery in it. You can get 31's with over 1000 CCA, darn sure enough to crank that Kubota in your Bobcat.

    Thanks for the info! I've got a lot to learn. I've had the machine for just over a year now and have only used it to plow snow. Would like to get into other stuff with it as well. Actually looking for an 18ft trailer as we speak.

    battery

    We don't have a bobcat dealer here so I went to the kubota dealer and got a 1150 cca battery for about $120.00. I couldn't find a gell battery with that many cranking amps.

    That sounds like a Group 31 battery. That's what I put in Bobcats, they're stout batteries. When I built my Monster Garage Booster, I put 4 Group 31's to boost 24V machines.

    Well I put a new spiral grid 770cca battery in my machine, and it has never turned over so fast or started so nice. The stock battery was only 700cca according to the part number. I also tapped inline and put a lockout on it, just incase anything was slowly draining the battery. So far its working great, just plowed with it tonight, first time in a week since it was last run.

    Have an 873 that is probably going to need a battery soon. Dealer wants $150. Seems high but he said that is because it is a hd battery. The bobcat will screw up other batteries because of all the jumping and jerking. Any ideas....

    A skid loader does put a lot of stress on a battery with all the vibration and bouncing. But a good quality group 31 will work fine for you. I don't know what suppliers you have in your area. NAPA, Interstate, Exide are a few that come to mind. A good quality battery will probably be between 90 to 120 $.

    I have a 763 and have been using a 750 cranking amp battery that was nearly new that we took from a car that we junked. It has been working fine for the last two years and will be replaced with same when it goes bad. While the bobcat is not in commercial service, it has been on a few construction sights in the last few years.

    I was never happy with how long batteries were lasting in our equipment until I started using Deka batteries. I dont know the difference, but they stand up to vibration and such better than anything else we tried. Reasonably prices too.

    Well, I'll throw in my experience. My 773 has a ? Walmart battery that is 6 years old, sits out at the farm in the cold, and is just now getting to be a problem, only on sub-20 degree days. Each of us has had different experiences--I had a Deka in my dump trailer and it started fizzing in less than a year.

    Walmart uses a different manufacturer now, and whoever was making those for Walmart now makes 'em for Autozone. If I remember right, the 84 month battery has a 3 yr replacement guarantee, and up to 84 months prorated. Though I buy as many things as I can through the "traditional" parts houses to give them my support, the nice thing about buying from Autozone or Advance is that they are open 7 days--if your battery breaks an internal connection on Saturday night, you can utilize your warranty. Buy from a "parts house" and you can't make the swap as easily.

    I'm guessing the 84 month battery at Autozone is less than $ 100. We run those in all our vehicles, and have not had any of them die before 5 or 6 years--one lasted 10.

    My 773 had a charging problem. It was putting out > 12 volts, but not 14+. The Denso alternator was ? $ 185 from Bobcat, and the number didn't cross to anything in the aftermarket. I took it to a rebuilder (ATCO: Quality Rebuilders over near Lovell Rd), and the guy quickly determined the one diode was bad in the integral regulator. But the unitized sealed-chip regulator was also proprietary--he didn't have a replacement. Not to worry--he split the sealed chip with his pocket knife, soldered on a generic diode hanging outside the chip (it wouldn't fit inside), and epoxy'd it back together. 15 minutes, $ 15. Has worked perfectly ever since. Check your alternator--it should be putting out 14.3-14.7 volts.

    I like Deltran's "Battery Tender". For dead batteries, they are way slow, but for maintenance, they are perfect and won't cook your good battery (and don't put out enough current to explode a bad one, either). They have an on-board charger but I like their quick-connect leads. Connect the lead to the bolts on the battery clamps, and just plug the pig-tail to the Battery Tender. We have darn near 2 dozen batteries to maintain, so we use the heck out of the Tender.
