The RJ-PLUS models have a different type of cell that is more durable and has a longer lifespan (you can compare their Manufacturer Rated Lifespan specs on the product pages). Because the RJ-PLUS cells are longer lasting, those models have a longer warranty. This means its a better value (it doesn't cost 25% more to get 25% more lifespan) and you won't have to replace the cell as often - which keep will more money in your pocket.
