Ryobi 5133000733 cordless lawn trimmer RLT1830LI been delivered on time and in perfect condition! Everything was good, gladly again! Did this replacement battery (4 AH), so you can really make meters ;-) Ryobi was unknown to me, but I am very pleasantly surprised, and have gained me other brand products! Batteries can be without problems use among themselves in various devices, what I really appeal to you, if there is one time flat.
