Your Horizon® P5 lithium-ion battery requires special care to ensure proper performance and long life.

Only use Horizon® P5 batteries with your Horizon® P5 concentrator.

Please follow these important guidelines to maximize battery performance and life:
• Store the battery in a cool, dry place. Store it with a 40-50% charge.
• If using multiple batteries, make sure each battery is labeled (1, 2, 3 or A, B, C, etc.) and rotate them regularly.
• Batteries should not be left on standby for more than 120 days at a time.
