How long does a cheap eBike last?

neutron said:

From what I understand, charging to 100% is ok as long as you use the battery right away and don't let it sit at 100% for long. I'd like to know that I can use 100% down to 20% to get the maximum mileage out of my battery. 90% down to 20% seems extra cautious just to get a few more charge cycles out of a battery.

Below is a very commonly reproduced graphic whose origin is Grin Technologies. Its simple and straightforward in terms of giving you a ballpark of the typical numbers.

The 100%-and-use-it-immediately reasoning is sound. The reason for this is the damage that occurs from a 100% charge takes place as the battery sits at that State Of Charge. Its still not good to have it touch 100%, but its not a big deal so long as you ride the bike immediately and draw down that charge.

Here's an article whose title is self explanatory. Note how old it is. Like I said above... Settled science. None of this is new info but there are plenty of one-trick knuckleheads on the internet who will pipe up and tell you how they charge to 100% and leave the pack sitting like that for weeks and them thar scientists are all full o' hooie. Listen to the people who know wtf they are talking about instead.

How to make a lithium battery last, or…kill it, if you like.

We have written in the past about tips that will help your expensive lithium battery pack last as long as possible. This article will cover some additional information about what happens inside the…

The above is a rather technical article. Skip to the conclusion section for the TL/DR version.

The 20% at the bottom end is not extra cautious. Its extra-generous. Really the battery is going to be happiest at about 40%. This is called Depth of Discharge and it is every bit as bad for the cells as a 100% SOC. The reason you don't hear so much about it is its tough enough to get the layman to accept and follow an 80% regimen. Telling someone that the battery is best kept in a narrower range is a bridge too far for the general consumer to wrap their heads around and accept.

The way you navigate thru this is always buy a bigger battery than you need and go a step further and make it bigger than you think you will ever need. At that point, if your battery is say double the size needed for you to do your stuff, then more limited percentage-use range is easy. FYI I am over 2500 cycles on an XL 52v pack that I bought in 2015. It was charged twice daily, once at home and once at work so I didn't have to drain it down hard and could live with a lower SOC when I pulled it off the charger.

Here's one place where DoD *is* discussed.

BU-808: How to Prolong Lithium-based Batteries

Once you know all this: Then what?

The answer is ride the bike and, if you need to, charge the crap out of it so you can ride the bike the way you want to.

Use the above info to know more about wtf you are doing. When you can, when it doesn't impact your enjoyment of the bike, treat that expensive battery right. When you buy another one someday, buy it smarter than you did the first time around knowing more about the subject than you did before.

As @HumanPerson noted, everyone does things differently. The science on this is pretty much settled: Charging to 80% increases pack life by a wider than 20% margin. In other words, you aren't just getting a 20% increase in life by foregoing 20% of the charge (the battery will actually last longer; the 800 cycle count is not set in stone, so to speak).Below is a very commonly reproduced graphic whose origin is Grin Technologies.

Well, you bought the ebike of your dreams! As far as we know, ebikes are types of bicycles that are powered by motor and battery.  The battery of the bike is the one that keeps it moving. Thus, you need to know how long do eBike batteries last. This way, you can work on taking care of your ebike battery and ensure it lasts at optimal performance for years.

Here is a general rule for calculating battery range

 

 

An ebike battery can work on a thousand charge cycle, meaning if you take care of the battery and it's a good quality battery, you could get up to 1,000 full charges before the cells start decay. But this also depends on the battery type that your electric bike is using. Before purchasing an ebike, you must check and do thorough research about it. Know before you buy.

 Lithium Batteries runs almost all ebikes today. They can hold up to 1000 cycles. No doubt, most ebike users, especially hunters, prefer it.

How to Prolong Your eBike’s Battery Life?

 

With proper care and maintenance, your ebike batteries can last up to three years. Bike batteries price is not cheap! You cannot just simply throw a bunch of your savings to buy new. That is why you need to learn some tips in prolonging your battery's life.

Check out some tips below.

 

Avoid Storing Your Battery in Extreme Cold or Hot Environment

For hunters, they often go on a trip most of the time. Their bike endures cold and hot environments, and the same goes for their battery. It is completely fine to ride your bike in extreme weather conditions, and your battery can endure that. But one thing that you must practice doing is storing your battery in a moderate temperature. That means that during winter, make sure to keep your battery and the bike itself in a place where it is not shortly exposed to the frigid cold.

 

Don’t Submerge Your Battery in Water

Yes! You read it right. Electric mountain bike is one of the best bikes in terrain because it can endure any obstacle. But one thing you missed to know is that some users fail to acknowledge that the battery of electric mountain bike is not waterproof. All ebikes are water-resistant, but not waterproof. If the water penetrates inside the battery, it will inevitably affect the state of your battery. So, don't ever submerge your battery in water.

 

Remove your Ebike’s Battery While Transporting

Don't forget to remove your battery in the bike during transit. The constant harsh vibrations from your car are not suitable for the internal components in the battery. Remove the battery during transportation, and this will also make your ebike lighter and more manageable.

 

Charging etiquette

When plugging your ebike battery in to charge, be sure to plug your battery or ebike in first before you plug it into the wall. The instant high voltage from the charger may shock your battery if you plug it into the wall first.

Tips

Storage and Charging

 

• Store your battery and bike in a room with room temperature between 35° to 80° F.
• Keep your battery away from the heat source.
• Avoid leaving your battery charging overnight. Make sure to disconnect the charger from the battery and the wiring after charging.
• Never completely drain the battery, but always try charging it to 100%.

Cleaning

 

• Before cleaning your bike, remove the battery.
• Do not use high pressure hoses when cleaning your electric bike.
• Do not immerse your battery in water. Use a damp cloth in cleaning it, simply wipe it and avoid direct contact of water.

 

Conclusion

So, How Long Do eBike Batteries Last? Typically, an electric bike’s battery can last up to 8 years. This depends on how you treat it and the battery type you are using. Make sure to regularly check the status of your battery so that you can act instantly if you find any problem.

When shopping for an eBike the battery supplier is also to be considered. Ebike brands that use high quality components tend to use good battery manufacturers. A general rule is you can't go wrong with Samsung and Panasonic. While LG is also up there as a good battery maker. Generally the cells are better quality and they hold, and release energy slower during use, instead of depleting quickly.
