RYOBI RB18L50 ONE+ Rechargeable Battery, 18 V, 5.0 Ah - 5133002433

RYOBI RB18L50 ONE+ Rechargeable Battery, 18 V, 5.0 Ah

RYOBI RB18L50 (article 5133002433) is a Lithium+ lithium-ion battery from the ONE+ 18 V platform with a capacity of 5.0 Ah. This is a high-capacity pack - one you reach for when the tool has to last a full working day rather than being swapped every half hour. Against a Lithium+ 18 V ONE+ 4.0 Ah pack, the RB18L50 delivers about 25% more runtime. This article is the battery on its own: no charger and no tool are included.

What ONE+ 18 V means

ONE+ is RYOBI's platform in which one 18 V battery powers the whole range - drill drivers and impact drivers, saws and angle grinders, vacuums, lights, trimmers, hedge trimmers, mowers and garden machinery. The RB18L50 is compatible and backward compatible with 18 V ONE+ DIY and garden tools, older generations of machine included. That is exactly why so many ONE+ machines are also sold in SOLO trim, without a battery - the owner already has a pack and pays only for the tool.

Lithium+ cells and IntelliCell

The cells are lithium-ion of the Lithium+ series - more power, longer runtime and greater durability than the brand's earlier generations of lithium batteries. On top of them runs IntelliCell: the electronics monitor and manage the charge and discharge of each cell individually, so that every cell is charged to 100%. In practice that means an even discharge, a longer life for the pack both in use and in storage, and better safety. The battery has no memory effect - it can be charged at any time without losing capacity.

4-LED charge indicator

The housing carries a four-LED fuel gauge, each LED standing for 25% of the charge - the readings are 100%, 75%, 50% and 25%. One button on the pack shows the state, with no need to put the battery into a tool or a charger. The pack runs at full power until it is empty, instead of fading away towards the end of the cycle, which is the characteristic behaviour of lithium packs.

Protection and construction

The pack has built-in electronic protection against overload and overheating and a reinforced impact-resistant housing. It weighs 0.7 kg, which for a 5.0 Ah capacity is a sensible compromise between endurance and how the tool balances in the hand.
