Assuming a daily charge/discharge a 1000 cycle battery needs to be replaced every 3 years. That would suggest that the majority of installers that guarantee the batteries for 10-15 years are going to lose their shirt on warranty replacements.
- pfdietz 4y agoWhich should tell you the 1000 cycle figure is not correct. I mean, they could test the cells to 1000 cycles even faster, by doing 3 charge/discharge cycles a day. They've had time to do that.
- scythe 4y agoBatteries tend to longer if you don't completely drain them in each cycle. I strongly doubt the typical driver covers 200 miles in a day — otherwise cars would only last three years. IIRC you can extend the useful life of a typical Li-ion battery significantly by only charging it to 80% most of the time.
