I just had the same thing happen to me with an 18V 4Ah Ryobi battery. It was not charging or showing any voltage at the connector post (FETs cut off apparently). I pushed 21V thru the whole pack until all the cells were showing around 4.1V. Still the voltage at the ...
About Photovoltaic Energy StorageThis means that, for a typical 10 Ah battery with a Peukert constant of 1.2, a 10 A discharge rate will discharge the battery in just 0.63 hours or 63 per cent of the expected time. Note that Peukert''s equation holds true for other types of cell technology, but the Peukert''s constant must be known for the cell type and age.
