With battery powered equipment, the portable power, hand held battery types are many. With some lasting a very short time...
But with the larger heavier wheeled equipment, like mowers, you will usually find a deep cycle, lead acid battery... They have been proven for many decades to be very reliable and long lasting ... the Neuton Battery is a lead acid and will typically have a 4 year + life cycle, and then is almost 100% recyclable ...
