Battery

A Battery is an object that has a base cost of $50 and allows for the storage of extra power. It becomes more relevant as you unlock new power stations, because if you do not have high level offices the battery allows for more power to be stored for future selling. They are also more cost-effective as the upgrade curve for the battery is 2x while the upgrade curve for offices is 10x. It is also great if you want to focus on production, since the battery can store excess power to power up production facilities.

The battery is very useful for idle players, mainly those who use an auto-clicker online, due to it not being against ROBLOX's terms of service.
