  1. Martin T. (verified owner)

    easy ordering process and fast delivery
    prefect replacement battery

  2. Aerich Chraibeck

    I’m replacing the battery in a cheap kids drive-around toy. Once ordered, I thought I would receive a 6 volt, 4.5 amp hour battery as stated in the descriptions and photos, but not quite. It’s still 6V, so it will work, but only 4Ah. Had it been presented as such I would have paid more for a different brand, but it was so inexpensive that it’s not worth the hassle of returning.

  12. Mark F.

    Ordered this battery for a friend who needed a replacement battery for a child’s rocking horse riding toy. Exact replacement voltage and amp hour rating. New Battery dimensions were smaller than original factory supplied battery (15+ years ago), but adapting was not a problem. Similar batteries were found at both lower and higher cost. Prompt shipment made this battery the best choice.

  37. jjay

    I was hoping this battery would be what I needed to resurrect a very powerful spotlight I own. The original battery finally had enough recharging and shelled out on me. The new battery was perfect in size and hookup so it gave me zero grief for the install. My powerful spotlight is back being what it was a few years ago. I’m happy about this particularly because I was close to tossing the spotlight out.

  38. Don B. Jennings

    I bought these for my deer feeder and glad I did. They were shipped quickly and packed very well. I have used others in the past that were not nearly as long lasting as these. They fit perfectly in the compartment and a great value.
