PowerHouse Lithium Limited Warranty

Warranty Period
15-year total warranty (10 years non-prorated) on deep cycle batteries 40Ah and up

Coverage

• Free replacement of a defective battery any time within the first 60 months.
• Free repair of the battery from year 5 through year 10. During years 5 to 10 you may instead choose an expedited replacement battery at 30% off MSRP, which skips the 2 to 6 week repair turnaround and comes with a new 15-year warranty.
• Warranty items are subject to a $60 shipping cost from PowerHouse Lithium; this fee is waived for the first year.
• Warranty replacement value is based on current MSRP. Batteries over 10 years old are offered a replacement at 30% off MSRP.

Registration
Register your battery with PowerHouse Lithium within 90 days of purchase. If it is not registered within 90 days, the warranty period begins at the battery's manufacture date. Proof of ownership is required, and warranties are not transferable; this limited warranty applies to the original purchaser and to United States residents only.

Inspection and Service
A battery may need to be shipped to PowerHouse Lithium for inspection. If the inspection finds a manufacturing defect, the standard warranty process is followed at no charge. If the issue is caused by user error or misuse (for example, a dead battery from improper charging or not recharging a fully drained battery, over-tightened straps or terminal bolts, or loose connections that melt the terminals), a repair and shipping fee of up to $150 may apply. Have the battery's serial number ready when submitting a claim; it is on the side of the battery and in the PHL app.

Exclusions
The warranty does not cover water damage, impact or collision; physical damage to the battery case or mishandling; products that have been opened, modified or tampered with; tampering with or removal of manufacture date codes; or use in applications other than those the battery was designed for, or above its rated continuous current. It also does not cover a battery that has reached its normal end of life (2,000 cycles), which may occur before the end of the warranty period depending on use.

Obtaining Warranty Service
Submit a warranty claim through PowerHouse Lithium's warranty application. The product may need to be shipped back for inspection.
