  1. Doesn't hold charge

    This battery has not held a charge since we got it with the 14RESA generator. There are other issues in perhaps the setup of the generator, but would not even turn over the starter after about five starts. Charged with trickle charger for a day, but still seems to run down very quickly. Early returns say bad product, or unprotected shipping. It arrived on top of the generator crate by itself.

  2. Make sure to order your battery with your generator

    AP Electric is the best. We order several generators, per year.

    Most distributors do not offer batteries. Including the battery with your order save time and headaches.

  3. Freebie with Kohler Generator

    This 'green top' Interstate battery arrived with my Kohler generator I ordered. Some of the electrolyte had spilled out during shipment, but I checked each cell and they were still at safe levels. I trickle charged the battery in the 2 weeks leading up to my generator's installation. This battery cranks over my 12RESV generator easily for quick starts.

  4. Great Battery!

    The shipping was excellent and thus far this is a great battery.
