RYOBI 18V Lithium-Ion 2.0 Ah Compact Battery (2-Pack)

This product is RYOBI 18V Lithium-Ion 2.0 Ah Compact Battery (2-Pack). Between versions of the same thing, it is usually the details — capacity, finish, what is included — that separate them. Read the setup notes before first use; most early problems come from a step skipped at the start. Where one is discounted, compare the size and edition rather than the headline alone. Keep the packaging and paperwork until you are sure it is a keeper — returns are simpler with both. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
