It does not require batteries, and the bypass valve feature allows you to maintain water flow even during maintenance.

The product dimensions are 12 x 12 x 48 inches, which should fit well in most home setups. Though it is ranked #100 in Water Softeners, its best-sellers rank in Tools & Home Improvement is relatively low, suggesting that it may not be as popular or widely used as other models.
