One of the most important components of an electric bicycle is the battery. There are major differences among the various types of batteries sold. So buyer, be aware!
People like electric bicycles because they exemplify an environmentally friendly lifestyle. The trick is to make “going Green” more than a slogan by using a battery that is less harmful to the environment.
Older Technologies in Electric Bicycle Batteries
Many electric bikes today use sealed lead acid (SLA) batteries, which are older technology but much lower in cost. But you get what you pay for. There are problems with 'going cheap' with these batteries:
• Long charge time - Up to 8 hours.
• Short cycle life - Good for up to 300 recharges, they need to be replaced every 12 months.
• Extremely toxic pollution produced by the used battery
• Heavy in weight - Increasing the load will decrease the life expectancy
Keep you're electric bike as light as possible! These low cost electric bicycles will cost you in the long run in additional batteries.
Some electric bicycle brands use a Nickel Metal Hydride (NiMH) battery, which are lighter, with a high energy density, both important for an electric bicycle. Their life is longer than the SLA, at 400 - 600 recharges. But this battery has shortcomings:
• They lose performance in cold conditions.
• They have a reputation for suffering from memory effect
• This technology is no longer state-of-the-art, so the cost of replacement batteries can be high.
