eBike Battery 101: What to Expect, and How to Take Care of It

When you invest in an eBike such as the Birch Grolar, on top of a powerful ride with dual 750W motors and 160Nm torque — you're also getting a long-lasting, reliable battery that’s crucial for powering your adventures. Whether you’re hitting rugged trails, cruising through the city, or embarking on an extended hunting trip, your battery is the heart of your eBike.

To ensure that “heart” stays pumping, proper care and maintenance are essential. Here’s what to expect from your Grolar's 48V 25Ah 1200Wh battery, along with some key tips for extending its life, especially on extended trips.

What to Expect from the Birch Grolar Battery

The Birch Grolar is designed for serious outdoor adventures with a 48V 25Ah, 1200Wh battery that can give you up to 45 miles on full throttle and 85 miles on pedal assist mode. With a 400lb payload capacity and climbing capabilities up to 40% (45% with pedal assist), this bike is built for handling rugged conditions. Its 26” x 4” puncture-proof tires also give you the stability and traction you need on tough trails, making it the perfect companion for off-road exploration.

While the Grolar’s battery is powerful, its lifespan depends heavily on how well you take care of it. Here's how you can ensure it lasts as long as possible.

Tips for Extending Your eBike Battery Life

Store Your Battery Properly

When you're not using your bike, storing the battery correctly is critical. If you're planning to leave your Grolar unused for a while, especially during off-seasons, remove the battery and store it in a cool, dry place. For optimal battery health, aim to store it at around 40-60% charge. This prevents the battery from becoming over-discharged or overcharged during long periods of non-use.

Avoid Charging in Extreme Conditions

The Grolar’s battery is designed to perform well in various conditions, but extreme temperatures can shorten its lifespan. Always charge your battery in temperate conditions, away from direct sunlight or coldness. Charging your bike’s battery in freezing or overly hot weather can cause irreversible damage.

Don’t Leave Your Battery Plugged In After Full Charge

Once your battery reaches 100%, unplug it to avoid overcharging. Even though modern eBike batteries like the Grolar's have built-in overcharge protection, it’s still a good habit to unplug the charger as soon as the battery is fully charged. Overcharging can generate excess heat and gradually reduce the overall lifespan of the battery.

Clean Your Battery Regularly

Just like any other part of your bike, the battery requires regular maintenance. Wipe down the battery terminals and connections with a dry cloth to remove dust or grime. Make sure to do this after riding through wet or muddy conditions. Keeping your battery clean will help ensure a proper connection and prevent dirt from interfering with the charging process.

Regularly Check for Damage or Wear

Inspect your battery and electrical connections regularly for any visible signs of damage. If you notice cracks, bulges, or any leakage, do not use the battery and consult a professional immediately. Catching issues early can help avoid unexpected failures during your trip.

Tips for Managing Battery Life on Extended Hunting Trips

If you’re using your Grolar on extended hunting trips, managing your battery life becomes even more important. Here are some tips specifically for long rides:

Charge After Every Ride

Even if you're out in the wild, try to charge your battery after every ride. It's tempting to wait until the battery is completely drained, but partial charges are actually better for the battery in the long run and help avoid deep discharge, which can harm battery health.

Keep Your Battery Well-Protected

During hunting trips, your bike is bound to face tough conditions. To ensure your battery stays safe, use protective covers or cases to shield it from debris, dirt, and moisture. Although the Grolar's battery is built to be tough with an IPX5 weatherproof rating, extra protection helps prevent any further damage from accidents. 

Monitor Battery Voltage Regularly

The Grolar comes with an easy-to-read battery indicator, so you can monitor your charge levels while on the go. Keep an eye on the voltage levels to avoid running out of power unexpectedly. On long trips, always try to keep the battery at around 30 - 50% charge when you’re far from home or a power source. This gives you a buffer if you need to use full throttle in a pinch.

Avoid Sudden Power Drains

If you're riding through challenging terrain during your hunting trip, avoid sudden full-throttle acceleration. Quick bursts of power can quickly deplete the battery. Instead, aim for a more consistent riding pace, which will help you preserve battery life and also reduce wear on other key components like the motor and controller.

Conclusion: Enjoy the Ride, Keep the Battery Healthy

Your Birch Grolar is a reliable companion for outdoor adventures, whether you’re navigating rugged trails, commuting in the city, or heading out on an extended hunting trip. With proper care, the 48V 25Ah 1200Wh battery will give you plenty of range, climbing power, and durability to keep you going for miles — up to 85 miles on pedal assist mode and 45 miles on full throttle.

By following these tips for battery care and maintenance, you can ensure your Grolar stays in top shape, providing reliable power no matter where your journey takes you. Whether you're tackling rough terrain or cruising through a quiet forest trail, with a little attention to battery care, your eBike can deliver years of adventure.

Happy trails!
