Battery maintenance

Use 12 VDC sealed lead-acid rechargeable battery (7 Ah or 18 Ah). The control panel supports
up to 18 Ah of battery. If you use two batteries, they must have the same capacity and you
must connect them using the D122/D122L Dual Battery Harness.
Replace the batteries every 3 to 5 years. If you install two batteries, replace them both at the
same time.
Record the date of installation directly on the battery.
