Our Promise

Summit Lithium batteries are built for reliability in harsh fishing conditions. Every battery we produce is backed by a 5-year limited warranty (2 years full coverage and 3 years 50% prorate) to you. If your battery experiences a failure due to defects in materials or workmanship, we will repair or replace it.

To start the warranty process, email:
📧 sales@summitlithium.com

This warranty protects you against defects that occur during normal, intended use of the battery, including:

• Manufacturing defects

• Component failures

• BMS-related failures

• Internal cell defects or early-life failure

If the battery is found defective under warranty, Summit Lithium will repair or replace it at no charge.

What This Warranty Does NOT Cover (Exclusions)

The following situations fall outside of the Summit Lithium warranty:

1. Misuse, Abuse, or Accidental Damage

This includes:

• Impact damage

• Water submersion

• Crushed or punctured cases

• Using the battery for an unintended application

• Drawing more current than the battery is rated for

2. Improper Installation or Modification

Examples include:

• Incorrect wiring

• Loose or corroded terminals

• Altered connectors

• Opening or modifying the battery case

• Running the battery in configurations not recommended by Summit Lithium

3. Unauthorized Sellers

Only purchases from authorized Summit Lithium retailers or SummitLithium.com are eligible.
Sales from third-party marketplaces such as eBay, Facebook Marketplace, or unverified sellers are not covered.

4. Improper Storage

Lithium batteries can be damaged if stored incorrectly. Excluded conditions include:

• Storing the battery fully depleted

• Leaving the battery connected to electronics for long periods

If the battery falls below safe voltage but is still recoverable, you may send it in for evaluation and repair (fees may apply if damage is not warranty-related).
