Demystifying Battery Warranties: What You Need to Know
Battery warranties protect against defects and performance drops, typically covering 3-10 years. They often include capacity retention thresholds (e.g., 70% after 8 years)
A standard battery warranty should come with at least 10 years of protection, though it can be shorter depending on how often you charge and drain your battery. Battery warranties typically won't reimburse for labor costs associated with installing new equipment or shipping fees for new equipment.
A battery storage system is a decades-long investment that a warranty can help protect. The less power your system stores, the more your home may need to draw from the utility company, which eats into your savings. A good warranty ensures that if your battery experiences a problem, that it will be replaced and your investment will be protected.
This limited warranty does not cover merely discharged batteries. If the battery is still not working correctly, determine if the battery is still within the total Limited Warranty Period. The applicable Limited Warranty Period is calculated from the date of sale to the original purchaser.
Prorated Warranty: After an initial free replacement period, this type allows for partial reimbursement based on how long you've owned the battery. For example, if your warranty lasts five years and your battery fails after three years, you might receive a discount on a new purchase based on age.
