Best Bike Batteries for eBikes & Electric Bikes Review

The growth in cycling in recent years has only been surpassed by the increase in Electric Bike sales. Electric Bikes, or eBikes, have played a significant part in getting people out cycling, whether it’s to aid recovery from injury, enabling older people to cycle further or to give them a bit of help uphill, electric bikes are here to stay and play an important part within the cycling spectrum.

We’ve reviewed a number of Electric Bikes recently and have been impressed by the quality of the Perry eHopper folding electric bike, versatility of the Swifty Electric Bike and price of the Hyuhome Electric Bike, which tops our list of cheap electric bikes in the UK.

Many of the entry-level electric bikes are fitted with basic batteries to power the electric motor, which see standard watts of 250W and 350W. Batteries are normally 8Ah, 10Ah or 13Ah but much larger power packs can be fitted and we’ve listed some of these below in our review of the best bike batteries for electric bikes.

Things to look out for when buying bike batteries within the UK is that they are fitted with British Regulations power units and plugs. Most batteries will be lithium-ion and many are rechargeable, saving a lot of money over the years of use. Charging options often come with USB chargers too, adding to the overall convenience, which for example may be recharging the battery after cycling to work, especially as your fitness increases and the distance you travel increases. Battery discharge should also be taken into consideration, and whilst all batteries lose power without being used, you should look for low discharge rates.

Suitability is of course important so just check that the battery is compatible with your eBike before making the final selection. Another consideration is battery weight. While it may appear attractive to buy a 23Ah battery rather an 8Ah version, larger batteries weigh more.

Frequently Asked Questions About eBike Batteries

  1. How long does an eBike battery last? A typical life expectancy of an electric bike battery is around 4 to 6 years, depending on how well its been maintained, frequency of use and weather conditions. An eBike lithium-ion battery will slowly dissipate its capacity over time.
  2. How long does it take to charge an eBike battery? An electric bike battery is likely to take around 3 to 5 hours to fully charge if starting with an empty battery. Partially charged batteries will of course take less time. Typical charging time is faster up until around 80% full with the remaining portion taking slightly longer as the battery slows down towards the end.
  3. Can I replace my eBike battery? Yes. Replacing an electric bike battery is quite simple on most bikes. Just contact the manufacturer for the battery model and swap on a like-for-like basis.
  4. How do I maintain my eBike battery? Ensure you fully charge the battery after every ride, regardless of how far you’ve ridden. Store your electric bike in a dry location (garage or shed) and try to avoid low temperatures. Covering the battery with an old blanket helps to avoid the cold.
  5. How far can I ride on a single charge of my eBike battery? The short answer is, it depends. A fully charged electric bike battery can be anything up to 80 miles but this depends on riding style, acceleration, weather, rider weight, battery size and so on.
  6. What type of eBike battery is best? The best electric bike batteries are lithium-ion batteries and are generally the ones most common, although lead-acid batteries are also available and whilst they are cheaper, they’re also three times heavier.
  7. How much does an eBike battery cost? Electric bike batteries range from around £150 to £450, depending on quality and capacity.
  8. How heavy are eBike batteries? A typical eBike battery varies in weight based on its size, capacity and its chemical component but expect the weight to be 4 to 8 pounds.
  9. How do I dispose of an eBike battery? Safely and securely. In the UK we have strict recycling schemes for all batteries but the good news is that you can either return the battery to the shop you bought it from or dispose of it at your local recycling centre.

Whilst it would be great to answer all of the FAQs it’s almost impossible as the answers are specific to each eBike and battery. For example, how long does an eBike battery last depends on the size of the battery, with an 8Ah battery having less power than a 23Ah battery. The more powerful battery also weighs more and when combined with the weight of the cyclist will ultimately require more power to propel the bike and rider. There is then the consideration of riding style and terrain. As you can see, these are just some of the complex factors in answering this question.

Having said that, please add your questions in the comments below and we will try to provide you will the best answer.
