C-rate<\/a> (or Charge\/Discharge Rate) is a measure of the speed at which a battery is charged or discharged relative to its nominal capacity. It is expressed as a multiple of the battery’s rated capacity per hour, and is a critical parameter in battery performance, safety, and longevity.
Impact of C-rate<\/a>
Higher C-rates increase power availability but may reduce battery cycle life and efficiency due to internal heat and side reactions.<\/p>\n\n\n\n

Lower C-rates are gentler on the battery, ideal for long-duration energy storage or slow-charging applications<\/p>\n","protected":false},"excerpt":{"rendered":"
