E-Bike Battery Care in Perth's Summer Heat
Heat is the number one enemy of e-bike batteries, and Perth summers are brutal. Here's how to charge, store and ride your e-bike so the battery lasts years, not seasons.
Heat is the number one enemy of e-bike batteries, and Perth summers are brutal. Here's how to charge, store and ride your e-bike so the battery lasts years, not seasons.
Lithium-ion cells age faster when they're hot. High temperatures speed up the chemical wear inside each cell, which permanently reduces how much charge the battery can hold. You won't notice it straight away. You'll just find that the ride to Cottesloe and back that used to leave you on 40% now has you limping home in eco mode.
Heat also increases the risk of a battery fault, which is why every e-bike manufacturer gives temperature limits for charging and storage.
On a 35-degree day, the inside of a parked car can get far hotter than the air outside. That's well past what any e-bike battery is designed to handle. If you're carrying your e-bike on a rack or in the back of the car, take the battery off and bring it inside with you whenever you can.
If you're going away over Christmas or won't ride for a few weeks, don't store the battery full or empty. Somewhere between half and two-thirds charge is ideal. Keep it inside, in the coolest room of the house, and top it up every month or so.
It sounds obvious, but a black battery sitting in full sun outside the café gets very hot, very quickly. Find some shade, or take the battery with you if it's quick to remove.
If you notice swelling, damage or a burning smell, stop using the battery and don't charge it. Get it checked.
Our E-Bike Service ($179) covers the motor, battery health, firmware, wiring and connectors, plus the full drivetrain and brake service that heavy e-bikes need. We have access to Bosch diagnostic software and work on Shimano, Bafang and other common systems too. If something's not right, we'll tell you straight and quote before any extra work.
And because e-bikes are heavy and awkward to transport, we come to you at home or work across Perth and Fremantle. No wrestling a 25 kg bike into the car.
