Handling tips for the slide-in batteries
After receipt, it is essential that you fully charge the lithium ion batteries immediately and store them in this way. They must be recharged after a maximum of 5 months. If the batteries are not charged, they can fall into a deep discharge state and then usually cannot be recharged, i.e. they are defective and can no longer be repaired. In such cases, no guarantee or goodwill can be given.
