      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.

      Bob,
      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.

      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.

      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.
