I’ve read many people saying that long drives aren’t good for battery longevity. What’s considered a long drive? Is my 32 mile each way highway Maine commute a long drive?
I’ve also read that the answer probably changes with the seasons.
Well, any rechargeable battery has a planned lifetime of an XXX number of charge/ discharge cycles.
So, those maximum number of charge/ discharge cycles will be reached MOST quickly if you use the battery's entire charge (100% down to 0% or 10%) and then recharge/ discharge again the next day...
If you only drive the car and use a partial charge range of the battery (e.g., 60% to 40%) and then charge again to 60%, there will be minimum "wear" on the battery. Then the battery may last 2X or more number of charges.
SO, if you daily drain the battery down significantly, you will wear out the battery than if you only partially use the battery daily.. For example, construction contractors use their cordless drills so much that they use up their rechargeable batteries in only a few months, where a casual user will use the battery in a drill for years...
