Warranty Policy

Last updated: September 16, 2026

Every LINEX LiFePO4 battery carries a 5-year limited warranty, and our home storage, solar and portable power products carry a 3-year limited warranty. This page explains what these warranties cover, what they do not, and how to make a claim.

What is covered

For the applicable warranty period (five years for battery models, three years for home storage, solar and portable power products) from the date of shipment, we will repair or replace (at our option) any covered product that fails due to a manufacturing defect. This includes:

• Capacity dropping below 70% of the rated value under normal use
• BMS failure or protection board faults
• Cell imbalance or abnormal self-discharge
• Swelling or leakage not caused by misuse

What is not covered

• Physical damage (drops, impacts, punctures)
• Water ingress beyond the product’s IP rating
• Reverse polarity or short circuits from incorrect wiring
• Charging with incompatible or damaged chargers
• Unauthorized modification or repair
• Damage from fire, flood or other external events

How to make a claim

1. Email [email protected] with your order number or invoice
2. Include photos and, where available, test data showing the issue
3. We respond within 2 business days and confirm the next step
4. Approved claims are settled with a replacement unit or a credit note
