    • Good Replacement Battery
Size: 7.76" x 5.16" x 6.26" (LxWxH)
Charged the battery fully then installed it on our Grasshopper 225. Fit the battery shelf without a problem. Cleaned the connection and sprayed them with an anticorrosion spray. Started the mower on the first try. Works well. Price is fair.

    • Seems like a good one. Time will tell..
Size: 7.76" x 5.16" x 6.26" (LxWxH)
Been a while since I bought a battery like this for my deere 240 mower. Super expensive these days. Geez what happened? Had to round up some different connectors. Old one had posts like car battery. We'll see how it lasts. If i had to do it again, I'd probably just get a lawn/garden battery from Walmart. ... show more

    • Work great
Size: 7.76" x 5.16" x 6.26" (LxWxH)
Exact replacement batteries for my drive mobility scooter. Easily installation, fit right in place of the old o es. Seemed to last longer and be a little stronger. Big savings over original replacements. Charged them immediately after installing to make sure they were topped off.

    • Poor performance
Size: 7.76" x 5.16" x 6.26" (LxWxH)
The battery did not last 6 months. We had to begin jumping it each time we used the mule. it will not recharge. I’m very disappointed in the battery. Interstate was once a high quality battery but it has been despeced.
