Ryobi ONE+ battery system

yes, I have a number of items in this range

Yes. Modern chargers handle both types

My original batteries didn't say One* either, but they all (original & new) have the part no BPP 1817. Actually, I might not have my original batteries any more, I know I've ditched some which wouldn't hold charge.

should be fine.

Mine ,both old ones purchased back in Nicad days when they were coloured blue and a couple of later items in the yellow colour from recent times. For a while I used both types of battery but the Nicads finally got too worn to be worth charging and I've purchased Li-ion. Batterys new but charger used .

The Faq page on the Ryobi Website has the question "Will all 18v Batteriws work with all 18v tools ?"

And answers "Yes, with the exception of Lithium-ion batteries. These batteries will not charge on Ni-cad chargers".

Seems a strange way of stating it though.

Yes, I saw that - but wasn't 100% sure "all" meant "ALL" or just all ONE+.

However, my old (pre-ONE+ ?) batteries look the same as current ONE+ NiCads (apart from the markings) - so I'm prepared to have a punt!

Based on what others have said, I think that the second part of the FAQ is saying (rather clumsily!) that if you've got NiCad batteries and a NiCad charger, and you then buy a Lithium-ion battery, you won't be able to charge it with your existing charger. Apparently the latest generation of chargers will charge either type.
