Why does the battery capacity change greatly
But wouldn''t this reduce your capacity i.e. your brand new battery now only has 80% of its rated capacity, which means more frequent recharge and all that. Even if you do charge it to 100% for the occasional road trips or whatever reason that you need to have the battery to last longer, I still don''t see the real benefit of capping your battery …
