⭐️ Purchased new batteries and carefully selected them. ⭐️ They have been conditioned for approximately two weeks. ⭐️ They are carefully created, starting with a low current of 0.5A and gradually increasing to a high current of 5A, while monitoring the condition and final voltage. ⭐️ Conditioning is performed until the final voltage reaches a satisfactory level. ※ These are not batteries that have been "awakened." ※ Judgment is based on the final voltage, not the high current tolerance. ⭐️ To prevent the batteries from arriving in a dormant state, a cycle will be applied just before shipping, but it is recommended to use them after 3 days from the shipping date. If the usage span is too short, the punch may be weak, and it takes time to awaken them if they become dormant, so a cycle will be applied. ⭐️ Due to the nature of the product, please purchase only if you have knowledge of batteries. ※ As a bonus, a battery case that holds four AA batteries will be included, but it is for cushioning purposes, and we cannot accept claims regarding it. ※ No claims and no returns are accepted. ● Shipping will be on weekdays only.
