It is, and I must say that I don't recall any, of any brand, failing within the first year.That's a very high failure ratio indeed!
In terms of the memory-dependent recollections I recently mentioned, what I 'convinced myself' back the, was that of the brands I's experienced, the longest-living (and probably cheapest) were the Homebase ones, and that the shortest-living (and probably most expensive) were the Bosch ones.
If nothing else, that did teach me that price and brand were very poor predictors of the life expectancy of a (cordless tool) battery!
