Cameron & Co 18V 4.5Ah Li-ion Battery

This Cameron & Co DS-CS-RTB820PW battery supplies 18 volts and 4.5 ampere-hours of lithium-ion capacity. It fits Ryobi ONE+ 18 volt cordless tools and replaces original packs such as the P105, P107, ABP1801, ABP1803, BPL1815, BPL18151 and BPL1820. The black housing matches the standard Ryobi form factor.

Replaces lower-capacity 18V packs

It upgrades from 1.5 Ah or 2.0 Ah batteries that came with early kits, giving noticeably longer run-time on drills, drivers, saws and lights. The jump is worth it when a single charge must last through a full day of intermittent use or when the original pack no longer holds a useful charge. It does not suit users who need a compact pack for tight spaces or who want a higher-voltage platform.

Steady output under continuous draw

Lithium-ion chemistry maintains consistent voltage until the cell is nearly depleted, so tools keep full speed during extended cuts or repeated fastening. The 4.5 Ah rating means the pack can deliver moderate current for longer periods without the voltage sag seen in smaller packs. Heat builds more slowly than in high-drain bursts, allowing sustained work before a cool-down pause is needed.

Questions about this item

Does the DS-CS-RTB820PW battery share the same slide-on form factor as the Ryobi P105 and P107 packs?

Yes, it uses the identical ONE+ slide-on design so it locks into the same tool and charger interfaces as the P105 and P107 models.

What is the correct way to seat the battery on the charger to avoid a false full-charge indication?

Push the pack down until the latch clicks audibly; a partial seat lights the charger but stops the charge cycle early.

After roughly how many charge cycles should I expect the 4.5 Ah capacity to drop to 80 %?

Typical Li-ion cells in this chemistry reach 80 % capacity after about 500 full cycles under normal use.
