Sealed lead acid battery for scooters, wheelchairs, toys, e-bikes, and other items. I received this battery used and was told it works great but is not holding a perfect, long-term charge anymore and needs recharging more frequently than when it was new. I tested it and it powered a car tire compressor just fine for five minutes before the compressor got too hot and I had to turn it off. Has nut-and-bolt positive and negative terminal posts.
Battery will make a fantastically cheap "spare" for use, i.e., when charging your main battery/batteries.
