> a good battery mower may last a very long time
However I’m worried about the availability of the mower’s battery 5-10 years from now. The battery packs have unique shapes, controllers, etc., which might be discontinued or become insanely expensive to replace in the future. If I were to buy a second mower battery as a backup, what would be the optimal strategy for maximizing the total life of my two batteries? Would it be best to:
- never use the second battery until the first one dies
- alternate between the two batteries
- something else?

Modern tools never let you do that, but if you store a "discharged" battery it will fully discharge(by self-discharge) over time. The best way is to charge it to 3.7V and then store it and check it at least yearly.
