    Hey guys, I was given a used old starter. But it did not have a battery. Is that something I can pick up at a walmart or car store?

    Is there a certian battery model number I should be looking for???

    Any help would be great. Hoping to buy it local and save a few bucks.

    Thanks guys!!

    Mine uses the same battery like you’d find in a lawn mower. It is a standard size.

    If it’s the self contained model look for an Interstate SP-40. It’s 340 cca which is a little more than the standard lawnmower battery. Be sure you have a good size gauge on the wires connecting it all. While mine is not self contained I use that battery with some longer welding cables. It spins over everything from a yammie to a 250 single with plenty to spare. Maintain it properly and they are good for 2 to 3 years.

    to help with your battery research, this the link to the Coleman site. http://www.colemanstarters.com/.

    The Coleman battery that is sitting on my bench that came out of a mini-starter measures 5 7/8 (w) x 3 5/16 (D) x 4 1/4 (H). Not sure if the older type starters took a larger battery.

    Ok, so I went to Autozone and they were trying to sell me a $80 battery.  How much should I be paying for a battery?? Is $50 about right or should I be able to find one cheaper?

    I just don’t want to buy the wrong battery.  If someone could post a part number for one or a link or two I would greatly appriciate it.

    My starter is kinda old. It looks a little like this style. It’s not this one but looks kinda like it. http://ekartingnews.com/forums/topic/kart-starter-old-style-coleman-starter/

    Thanks guys

    Interstate battery part# SP-40 or it’s equivelent.
    Batteries are like tires. You get what you pay for.
    Compare the cca’s (cold cranking amps). The higher the better.
    You might also try at Walmart or Tractor Supply.

    I have the same starter.



    Napa P# 8229 the Lawn and Garden Battery is what I have in mine. $50

    Starts my KT100, Animal and PRD Fireball(when needed).

    That will work too. All the companies use many different part numbers but there is a generic group number for them all. You are looking for a group U1.


    Bob Spedding

    Thanks guys.  I was thinking something more like this battery.


    It would be a lot lighter and my kids could use it to start the kart without being to heavy.

    Would this be ok ???

    Look into Shorai lithium ion batteries.  They cost a bit more but you can find good buys on ebay.  They are very light, pack a punch, environmentally friendly, fast charging, and hold a charge for over a year.
