My EV doesn't go as far on a charge anymore
Some range loss over the years is normal as the battery ages. A sudden drop is different and often comes from low tires, heavy AC use, a dragging brake, or a battery cell group that is weak. A battery health check shows how much capacity you really have left.

What to do right now
What to do right now
- 1Check all four tire pressures. Low tires cost an EV a lot of range.
- 2Compare range on similar trips, same speed, same AC setting. Fast highway runs use more.
- 3Precool the car while it is still plugged in so the battery is not doing that work on the road.
- 4Write down the estimated range at full charge now and compare it with what it used to show.

EV battery health check
We read the battery's real capacity and check for any cell group that is weaker than the rest.
See the serviceEV diagnostics
If the battery is healthy, we look for software faults, heat pump or cooling issues, and brakes that drag.
See the serviceTires
EVs are heavy and wear tires fast. Low pressure or the wrong tires can cut your real range.

Does Miami heat hurt my EV battery?
Heat is harder on batteries than cold. Park in shade when you can, avoid sitting at 100 percent in the sun, and let the car's cooling system run. Those habits help the battery last.
How much range loss is normal?
It varies by car and use. A slow, steady drop over years is normal. A big drop in a few months is not, and it is worth a test.
Does charging to 100 percent every day hurt the battery?
For most EVs, daily charging to around 80 percent is gentler. Charge to full before a long trip. Check your owner's manual for what your car recommends.
Is my battery still under warranty?
Many EV batteries have a long capacity warranty from the maker. A health report from us gives you real numbers to bring to the dealer if it qualifies.
