Warranty Information

Our Commitment

Every battery pack manufactured by SES carries a product warranty that reflects our confidence in our materials, our assembly process, and our validation standards. We stand behind what we build, and we make the warranty process straightforward when it needs to be used.

Warranty Period

SES battery packs are covered under warranty for a period communicated at the time of quotation or order confirmation, based on the pack type, application, and agreed supply terms.

For standard OEM packs, typical warranty periods range from 6 to 12 months from the date of dispatch. For medical-grade packs supplied to healthcare OEMs, warranty terms are confirmed in writing as part of the supply agreement.

To confirm the warranty period applicable to your order, please refer to your quotation document or write to info@sesbatteries.com with your order reference.

• BMS or protection circuit failures not caused by external misuse or out-of-spec operation
• Premature capacity loss below 80% of rated capacity within the warranty period, under the specified operating conditions confirmed at order stage
• Connector or cable failures attributable to a manufacturing defect

What the Warranty Does Not Cover

• Operation outside the specified voltage, temperature, or current limits for the pack
• Physical damage from improper installation, handling, dropping, or storage
• Exposure to water, moisture, or chemicals beyond the pack’s rated ingress protection
• Modifications, repairs, or alterations carried out without SES’s prior written consent
