  The capacity of a Prius battery indicates how much energy it can store. The capacity is between 20 and 60 kWh. A higher capacity battery can drive longer distances before needing a charge.

• Cycle life

  Cycle life is the number of times a battery can be charged and discharged before it loses capacity. The cycle life of a Prius battery is between 500 and 1500 cycles. After that, the battery capacity will decrease, and it won't hold as much energy.

• Energy density

  Energy density is how much energy is stored in a given amount of space. A higher energy density means a battery can provide more power while taking up less room. The energy density of a Prius battery is 100–300 Wh/kg.

• Temperature range

  Temperature is an important specification when it comes to Prius batteries. Extreme heat or cold can damage them. Prius batteries have an operating temperature range of 0–40 °C (32–104 °F). This range keeps the batteries functioning well.

Maintaining a Prius battery is important for its performance and lifespan. Here are some tips:

• Regular software updates: Software updates from the manufacturer can improve battery performance. Follow the instructions for downloading and installing updates.
• Use the recommended battery charger: Always use the charger suggested by the manufacturer. Other chargers may not charge the battery properly and could damage it over time.
• Avoid deep discharging: Try not to let the battery level drop below 20%. Deep discharging puts extra stress on the battery and can shorten its life.
• Keep the battery clean: Periodically check the outside of the battery for dirt or debris. Gently wipe it clean with a damp cloth. A clean battery will perform better.
• Monitor battery health: Some vehicles have a battery health monitoring system. This system lets you know if the battery is starting to degrade. If it shows a problem, take the car in for service.
• Avoid extreme temperatures: Try not to expose the battery to very hot or cold conditions. Extreme temperatures can damage the cells and reduce their capacity over time.
