Batteries purchased from our website come with a 12-month warranty. Please provide pictures of the issue to our customer support team to start the after-sales process.
We offer a 30-day return policy. Please ensure the product is in brand-new condition and contact our customer support team to initiate the return process.
Begin with a small current discharge (set to 1-2A), then perform 2-3 charge-discharge cycles with a 1A current to activate the battery.
Each cell should have a voltage between 3.70V and 3.90V. Batteries typically ship with 30-60% charge. If you have further questions, feel free to reach out to our customer support team.
