Warranty Terms & Conditions
Sealed Energy Systems LLP (“SES”) designs and manufactures batteries, battery packs, chargers, charging systems and related electronic products for professional, industrial, medical, communication, defence and OEM applications.
SES warrants its products against defects in material and workmanship when the products are installed, operated, charged, stored and maintained in accordance with the applicable SES product documentation and specified operating conditions.
Material & Workmanship
Products supplied by SES are warranted free from defects in material and workmanship during the applicable warranty period.
Specified Operating Conditions
Products must be installed, operated, charged, stored and maintained in accordance with the applicable SES product documentation.
Authorised Sales Channels
The warranty applies only to products supplied directly by SES or through an authorised SES sales channel.
Product Evaluation
Returned products are subject to technical inspection and evaluation by SES.
1. Warranty Coverage
Subject to the terms stated below, SES warrants that products supplied by SES will be free from defects in material and workmanship during the applicable warranty period.
The warranty applies only to products supplied directly by SES or through an authorised SES sales channel and is valid for the original purchaser unless otherwise agreed in writing.
The applicable warranty period shall be as specified in the relevant:
- SES quotation or commercial offer
- Purchase order acknowledgement
- Invoice
- Product datasheet or technical specification
- Supply agreement or project contract
Where a project-specific warranty has been agreed in writing, those agreed terms shall take precedence.

3. Battery Warranty Conditions
Battery performance is affected by operating temperature, charge and discharge rate, depth of discharge, storage conditions, application profile and number of charge/discharge cycles.
Warranty coverage therefore applies to manufacturing defects and does not constitute a guarantee that a battery will maintain its original rated capacity throughout its service life.
Normal reduction in available capacity resulting from ageing, cycling and normal use is considered a characteristic of rechargeable batteries and is not, by itself, considered a manufacturing defect.
For warranty consideration, the battery must have been:
- Charged using an SES-approved or technically compatible charging system.
- Operated within the specified voltage, current and temperature limits.
- Stored within the recommended state-of-charge and temperature conditions.
- Protected from excessive mechanical shock, vibration, moisture, contamination and heat beyond the specified product limits.
- Used only within the intended application or an application approved by SES.
For smart batteries, diagnostic information such as cycle count, event history, temperature history, voltage history, protection events or other stored battery-management data may be reviewed by SES during warranty assessment.
4. Charger Warranty Conditions
SES chargers and charging systems are warranted against manufacturing defects when used:
- With the specified input power source.
- With compatible batteries and battery chemistry.
- Within the specified environmental conditions.
- Within the rated electrical load and operating parameters.
- In accordance with the applicable user manual and technical documentation.
Damage caused by incompatible batteries, incorrect wiring, abnormal supply voltage, unauthorised modification or use outside the specified operating limits is not covered.
5. Warranty Exclusions
The SES warranty does not cover damage, malfunction or deterioration resulting from:
- Normal wear and ageing.
- Normal battery capacity degradation.
- Improper charging or use of an incompatible charger.
- Deep discharge or prolonged storage in a discharged condition.
- Overcharging, over-current or operation beyond specified electrical limits.
- Incorrect installation or wiring.
- Reverse polarity or short circuit caused externally.
- Improper handling, transportation or storage.
- Mechanical impact, crushing, puncture or physical abuse.
- Exposure to liquids, chemicals, excessive humidity or contamination unless the product is specifically rated for such exposure.
- Fire, flooding, lightning, excessive heat or other external environmental events.
- Operation outside the specified temperature range.
- Unauthorised repair, modification, disassembly or alteration.
- Damage to connectors, cables or terminals resulting from misuse or improper mating.
- Use in an application substantially different from that specified or approved by SES.
- Failure of equipment external to the SES product.
- Cosmetic deterioration that does not affect product functionality.
- Removal, alteration or illegibility of the product serial number, identification label or traceability marking.
Consumable components and accessories may have different warranty provisions where specifically stated.
6. Custom & OEM Products
Many SES products are engineered specifically for customer applications.
For custom-designed battery packs, chargers, electronic assemblies and OEM products, warranty coverage shall be subject to the approved product specification, interface requirements, operating profile and commercial agreement applicable to that project.
Changes made by the customer to the equipment, electrical interface, communication interface, charger, load profile or operating environment after product approval may require technical revalidation by SES.
Warranty coverage may be affected where the product is operated outside the originally approved application conditions.
7. Warranty Claim Procedure
If a product is believed to be defective, customers should contact SES Technical Support before returning the product.
Please provide:
- Product model number
- Product serial number
- Invoice or purchase reference
- Date of purchase
- Description of the observed problem
- Application and operating conditions
- Photographs, diagnostic information or test data where applicable
SES may request additional information or remote diagnostic testing before authorising a product return.
Products should not be returned without prior return authorisation from SES.
8. Product Evaluation
Returned products are subject to technical inspection and evaluation by SES.
Depending on the product, evaluation may include:
- Visual inspection
- Electrical testing
- Capacity testing
- Charger functional testing
- BMS diagnostic review
- Communication-interface testing
- Review of fault or event history
- Mechanical and connector inspection
SES will determine whether the reported condition is covered under warranty based on the inspection findings and applicable warranty terms.
9. Warranty Remedy
Where SES confirms that a product has failed because of a defect covered under warranty, SES may, at its discretion:
- Repair the product;
- Replace the defective product or component; or
- Provide another commercially reasonable remedy.
A repaired or replacement product does not normally restart the original warranty period and remains covered for the balance of the original applicable warranty period unless otherwise agreed in writing.
Replacement products or components may be functionally equivalent to the originally supplied product.
10. Transportation & Return Charges
Return and transportation arrangements shall be coordinated with SES before shipment.
Responsibility for freight, insurance, customs duties, taxes and associated logistics costs will depend upon the applicable commercial agreement and the outcome of the warranty evaluation.
Lithium batteries are regulated for transportation. Customers must comply with applicable dangerous-goods transportation requirements when returning batteries to SES.
11. Products Found Not Defective
Where evaluation determines that the returned product is functioning within specification or that the reported failure is not covered by warranty, SES may provide an inspection report and, where appropriate, a quotation for repair, replacement or further testing.
Testing, freight and associated service charges may apply.
12. Limitation of Warranty
SES’s warranty obligations are limited to the remedies expressly described in these terms or in the applicable contractual agreement.
To the extent permitted by applicable law, SES shall not be responsible for indirect, incidental, consequential or commercial losses arising from product failure, including loss of production, loss of use, loss of revenue or damage to other equipment.
Nothing in these terms shall exclude or limit any liability that cannot legally be excluded under applicable law.
13. Technical Documentation Takes Precedence
Product-specific technical documents, including approved specifications, drawings, datasheets, operating manuals and project agreements, form an integral part of the warranty conditions.
Where product-specific warranty requirements differ from these general terms, the formally agreed product-specific or contractual terms shall prevail.
