BU-802: What Causes Capacity Loss?
A pack should be replaced when the capacity drops to 80 percent; however, the end-of-life threshold can vary according to application, user preference and company policy.

Yes, battery packs do lose power over time. This phenomenon occurs due to natural chemical processes within the battery. As battery packs age, their internal chemical reactions and
Generally speaking, your EV may use 12 to 15 percent more
Generally speaking, your EV may use 12 to 15 percent more energy than what you add to your battery. That number could be lower or higher depending on charging conditions. There are a
You might assume that a brand-new battery, sealed in its original packaging, stays fully charged forever— but that''s a myth. Even unused batteries gradually lose power due to chemical
A battery''s capacity, whether it''s in amp-hours (Ah) or watt-hours (Wh), shows how much energy it can store and release. Losing capacity doesn''t mean it''s completely dead—it just can''t give
Using a power pack on an appliance with an old Li-ion battery will not use any more power than normal. The power pack will simply take over from the internal battery to supply the power the
This is called "capacity loss" meaning the battery pack holds fewer kiloWatt-hours than when it was new, and that means the electric car will have less driving range.
Lithium-ion batteries lose power as they get older. This happens because of chemical aging, self-discharge, and temperature changes. Do not overcharge or drain your battery too much.
Said another way, as the battery degrades -- is the car losing efficiency (it costs more per mile to drive), or is it simply losing capacity (cost per mile will remain the same, just smaller storage)?
Discover the intriguing world of batteries! Our deep-dive explores what causes a battery to lose capacity, unveiling the science behind this everyday phenomenon.
