A counterweight system for a battery of a material handling vehicle is provided. A counterweight case can be configured to receive the battery. One or more spacers can be disposed within the counterweight case. The one or more spacers can space the battery apart from one or more internal walls of the counterweight case, when the battery is received in the counterweight case. In some cases, the spacers, along with vent holes, plugs, brackets, and/or a cover (e.g., a blanket cover) can help to protect the battery from environmental factors (e.g., heat, cold, vibrations, contact, and so on).
