Dear TallGrassBlues,

We appreciate you letting us know and we apologize for your experience. We are happy to hear Greenworks Success Team, were able to support you with this warranty claim in a timely manner. Greenworks is committed to making sure customers are 100% satisfied with the quality and durability of each purchase. We are sorry to hear about the experience you have encountered with this battery. The overall battery life is dependent on many factors such as where they have been stored, charged, and handled. When the battery will not be in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging. It is recommended to store the battery with a full charge, and if it is being stored for a period where no use is expected, to check on the charge every couple of months. If you notice the charge has dropped, we advise charging the battery back up to full before returning it to its safe storage place. Following these steps will ensure you receive the most of the battery life.
