HP One Time Battery Replacement Service offers a convenient method for replacing out-of-warranty batteries. Under this service, one (1) replacement battery will be provided if the originally purchased battery drops below 50% charge capacity during normal use or if a cell failure has occurred before the 50% limit is reached. This service includes the replacement battery, standard ground shipping within the United States, and recycling options. This HP Care Pack service is inclusive of the HP Limited Warranty that comes with the product; it does not replace the limited warranty but provides for a longer period of time during which you are protected from battery failure. The HP Limited Warranty provides originally installed battery coverage for the lesser of either a 1-year limited warranty period or the length of the limited warranty for the HP notebook PC with which the battery is shipped. This HP Care Pack service terminates after you receive a battery replacement or when the service period expires on the supported product, whichever event occurs earlier. For situations where the original battery is still covered under the HP Limited Warranty, you should call 1-800-633-3600 for warranty support. For batteries no longer covered under the HP Limited Warranty, the HP One Time Battery Replacement Service should be invoked. To initiate the battery replacement service, you must download and/or run the HP Battery Check program and call the HP Battery Replacement Service Center at 866-927-3113 and report the battery check diagnosis in order to validate that a replacement battery is needed. If the battery meets the replacement criteria, you will be asked a number of questions regarding the coverage program purchased, the replacement battery requested, and the address to which the replacement battery should be shipped.
