At Wildhaven Curator, we’re here to help with warranty questions about your BigBattery purchase. Our team can help identify the applicable coverage and coordinate manufacturer support.

Manufacturer Warranty Overview

Coverage depends on the product, purchase date, and applicable manufacturer terms. BigBattery provides lifetime technical support and automatically records battery warranties through serial numbers and QR codes.

Coverage and Duration

• BigBattery Batteries: Purchases after October 2024 carry 12-year repair/replacement coverage for material and workmanship defects.

• Earlier Battery Purchases: Purchases before October 2021 carry three-year coverage; purchases from October 2021 through October 2024 carry ten-year coverage.

• BigBattery Chargers and Accessories: One-year coverage from purchase for qualifying defects under normal use.

• BigBattery APEX-6.5K and APEX-10K Inverters: Five-year limited warranty. Contact us for model-specific eligibility, exclusions, and service arrangements.

• Other Manufacturers: Products branded EG4, Sol-Ark, Victron, Growatt, AIMS, or another manufacturer follow that manufacturer’s warranty.

Battery Warranty Service

BigBattery assesses returned batteries before approving service. Repairs or refurbished replacements may be provided.

If a new replacement is provided, beginning in year two, the customer may owe one-twelfth of its cost per year of ownership.

Capacity-loss claims below 25% are excluded. Manufacturer capacity testing is free; results determine eligibility.

Conditions and Exclusions

Battery exclusions include misuse, improper installation, environmental damage, improper charging, over-discharge, and unauthorized modification/disassembly.

If charge falls below 10%, recharge within 48 hours. Contact BigBattery immediately if charging is impossible.

Charger coverage excludes misuse, physical damage, unauthorized work, incompatible equipment, and operation outside specifications. IP65 charger coverage is nontransferable; repaired/replacement chargers retain the original warranty dates.

Battery Warranty Transfers

• Stationary batteries must remain at the original location; ownership-transfer documentation must be emailed within 30 days.

• Mobile batteries must remain in the original vehicle/system, with original purchase proof and a documented ownership chain.
