Questions about this item

Does the 2-pack include the 12 V lead-acid cartridge #2 model 229 for my SU420NET, or must I buy wiring separately?

The package contains two 12 V lead-acid cartridge #2 units (model 229) that fit the SU420NET; no extra wiring or hardware is required for installation.

Should I choose the 2-pack of cartridge #2 or a single cartridge for the SU420NET?

The SU420NET uses two cartridges, so the 2-pack replaces the complete set in one purchase, while a single cartridge would only cover half the unit.
