I have just purchased an EGO leaf blower with 5 amp battery and charger. I plan to also buy a leaf blower, currently available at $180 complete with 2.5 amp battery and charger, or $150 alone. Even if I consider the additional charger worthless despite its individual $70 list price, I am paying only $50 for the battery, while it would be $150 if bought separately. I do not use these tools frequently, so I will not have to worry about running out of power using one battery for both pieces, or all 3 if I also get a chain saw (I can always wait to finish my occasional job until next day). So do I pass up what looks like a real bargain on a second battery for my tools, or do I spend the extra $50 so that I can have another at 1/3 the separate cost in preparation for my original battery dying in 3 years? And then how likely is it that the “new” $50 battery will die on the shelf as it waits 3 years to be used? (I’ve seen the advice to run it occasionally.) Any thoughts for one who likes to get the best deal? And while I’m not complaining about the prices, I wonder: why the weird pricing of these individual components?
