As our customer support receives numerous questions about e-bike batteries, we’ve decided to share some essential tips on how to properly care for your electric bike battery. We’ve previously covered related topics like battery testing, beginner’s guides, and how to boost your e-bike’s performance.
**How to Charge an E-Bike Battery**
When you’re looking to buy a new electric bike, one of the first things you might wonder is how to charge the battery. The process is straightforward: start by removing the battery pack from your bike, then turn off the switch on the battery. Next, attach the charger to the battery and plug it in.
Lithium-ion batteries, which are the most common type used in the rapidly growing e-bike industry, are designed to be safe even if you unplug them before they're fully charged. Charging usually happens in two stages: the first 80-90% is the fastest, so even if you stop charging early, your battery will still be mostly charged.
Some customers also ask if they can replace their battery. The answer is yes — you can replace it at any time without affecting the bike’s performance.
**How Long Does It Take to Charge an Electric Bike?**
Most e-bike chargers use a red LED to indicate that the battery is charging, switching to green when it's fully charged. The total charging time depends on the battery size, typically ranging from 2 to 6 hours. For example, if your e-bike has a 40-mile range and takes 2 hours to charge, that means it gains about 20 miles per hour of charging.
**Do E-Bikes Charge While You Pedal?**
Some e-bikes allow you to recharge the battery while riding, adding up to 5-10% of range. However, this feature can increase the cost of the bike and may make pedaling more difficult. If you're unsure about your battery life, it's best to avoid relying on this feature during long rides.
**Charging Your E-Bike Battery at Home: Key Tips**
Here are some important guidelines to help you take better care of your e-bike:
1. **Charge regularly.** Even if you don’t plan to use your e-bike for a while, regular charging is crucial. Unlike traditional bikes, e-bikes require more attention during storage. Try not to leave them unused for too long. Before storing your e-bike, clean it thoroughly, charge the battery, and check its condition — these steps ensure its safety and performance over time.
2. **Avoid extreme temperatures.** When you first get a new e-bike, charge the battery fully within 12 hours. This helps activate all the cells and prepares the battery for use. Avoid charging in very cold or hot conditions, as both can damage the battery. In winter, bring the battery indoors before charging, and in summer, keep it in a cool place.
3. **Don’t overcharge.** Leaving your battery on the charger for days can lead to inefficient charging cycles. Instead, set a timer on your phone to remind you to remove the battery once it’s done.
4. **Charge new batteries for 12 hours.** A full initial charge ensures the battery is ready for use and helps maintain its efficiency over time.
5. **Don’t store a completely drained battery.** If you need to store your e-bike for a while, keep the battery between 40-70% charge. Storing it empty can significantly reduce its lifespan.
Remember, proper storage is key to maintaining battery health. Most standard e-bike batteries come with a 3-year warranty, covering at least 70% capacity. At Delfast, we offer a 2-year warranty on batteries and a lifetime warranty on the frame. We also provide various credit options to make buying easier and more convenient for customers worldwide.
