Maximizing Battery Life

There are many myths about batteries and many people do not know how to treat them well which results in reduced mileage and shorter battery life.

Here are some useful facts about sealed lead acid (SLA) batteries which are found in most electric vehicles.

  • Lead-acid batteries do not have a memory effect, so you don't need to worry about charging them often

  • SLA batteries retain nearly their full charge for two months or more just sitting on the shelf, unattached to a charger.

  • SLA batteries can be severely damaged by being deeply discharged to down below 75% of their rated voltage.

  • Typical batteries have a life of 300 recharge cycles before reaching 80% of their capacity.

  • Batteries not have the same amp-hour (Ah) capacity when discharged at different rates

Everyday Tips

The following tips will make a big difference to the life of your vehicle.

Recharge Often

As and electric vehicle owner, you should charge up your vehicle as often as possible. Do not wait till it gets empty since it will decrease the life of your battery. The depth of discharge (DOD) dramatically affects your battery. Ideally you should plug in your vehicle to recharge after every drive.

Accelerate Slowly

As I mentioned above, a battery does not have the same capacity when discharged at different rates. If, for example, your batteries are 20Ah (typical to most scooters), always driving at full throttle will make them give you only 50% to 70% of their actual rating. This means that when you drive your vehicle aggressively it will effectively reduce the range since it takes more power. To increase your mileage, try to accelerate slowly rather than using full throttle. The initial acceleration of your vehicle takes excessive current from your batteries and hence regular acceleration and braking will quickly drain them.


Storage Tips

When going on a holiday, recharge your batteries fully before leaving. If you are going for longer than one month, have someone come and recharge the battery every month.

Please make sure that the battery charger cuts off after maximimum of 6-8 hours. if charger does not cut for a significant period say 12-18 hours or more there is obviously a charger malfunction. This can lead to battery overcharging and can result in battery bulging & premature failure. Take the charger to your dealer & have the fault rectified. This is extremely important.

i am a terrified at the pollution and thinning of the ozone layer. But! what is the use of making electric vehicles, As 80% of the people are not interested in E-V. Aleast planting plants is not encouranging. So, My opinion is in place of city buses run electric city trains, like in kolkata and use e-vehicles. So, E-mail your opinion on my comment to
