I've got a 2013 Leaf that I bought used about 4 years ago. Lately it's only getting maybe 60 miles per charge when it used to do 80-90. Is this normal battery degradation at this point, or could something else be wrong? Should I be looking at battery replacement costs?
It's probably not just battery degradation at this point - there's likely something else going on. A 2013 Leaf losing 25-30% of its range over 4 years is steeper than the typical curve. Most older Leafs degrade slower than that, especially if they haven't been sitting in extreme heat constantly. First thing to check: what's your charging routine? If you're regularly charging to 100% and letting it drop to near-empty, that accelerates wear. Also look at your battery health indicator on the dashboard if it shows one, or grab a scan tool to pull the actual battery stats - you want to know what your capacity is sitting at now.
Weather and driving habits matter too. Cold temperatures tank your range temporarily (that's normal), but if it's been hot where you live and you charge aggressively, your battery could've taken real damage. That said, battery replacement on a 2013 Leaf is pricey - we're talking $5k-8k depending on where you go, so it's worth ruling out other stuff first. Have a proper EV tech run diagnostics before you commit to anything. Could also be a degraded onboard charger or pack balancing issues that are easier fixes. Get the numbers on the battery's actual state of health and go from there 🔋
