I bought a second battery two years ago soley to increase my range. Cost about $1,000. Today same battery sells for about $1,400. A second battery might be very useful for you since you intend to keep your battery only 60% charged. Less than 2/3 charge is also less than 2/3 range.

Stocking up on replacement parts that you might need someday (uncertain) but don't need right now makes sense only in some cases: You suspect the part shortage continues, or you suspect the part will be discontinued The part is likely to fail or wear The part is not very expensive and not likely to become much much cheaper soon, instead maintaining its ...

Partly in response to @ChrisH, I thought I should check how much capacity a lithium ion battery potentially loses in prolonged storage. The answer is complicated. I think that potentially, lithium ion batteries can last several years in storage with only some loss of capacity. However, the answer is a bit more complicated than that. Battery University has an ...

Li-ion batteries lose some capacity in prolonged storage no matter the state of charge, so I certainly wouldn't buy one now. Apart from the option in mattnz's answer (battery rebuild services, which can be slow and cost more than a replacement), you have an alternative: Keep an eye on the condition of the rest of the bike, the battery capacity (as measured ...

Probably better asked on Electrical Engineering SE. From my RV experience, batteries have a limited shelf life no matter how well they are stored. Shelf life reports vary from 2-6 years (I thought longer). Regular recharging (6months to a year) will extend the storage life. Lithium have a typical useful cycle life of 1000-2000 cycles. If you are riding ...
