Why is My Scooter Battery Not Holding Charge?

INTRODUCTION

Your scooter battery should be routinely checked on a regular basis to ensure it does work properly, the way you would expect it to work, as batteries are prone to malfunction if left untended. Spending a few minutes from time to time to maintain it goes a long way in keeping your battery in perfect shape and a guaranteeing long battery life.  

When it comes to battery charge issues in particular, these can be due to quite a number of different problems. Most of the time, these problems have to do with the battery itself. The battery does not hold charge because it has worn out from long use, or because it might have grown defective. In oher cases, the battery may even broken or ruptured.  

HOW TO MAINTAIN YOUR SCOOTER BATTERIES

Most people fail to realize that whenever is scooter is left unused for extended periods of time, its batteries slowly discharge. Once their level of charge falls below a certain low level, your scooter’s batteries are in danger of dying away completely, as your charger will no longer be capable of bringing them back to their former shape. There are two easy steps you can take to minimize the chances of this happening to you:

  • ​Plug in your battery charger every two weeks, at night time, just before you head for sleep. Unplug it the next morning. This assumes you have a removable pack of batteries, which you can access without too much hassle. Follow through with this through the winter.
  • ​In case you do not have a removable battery pack, you should know that sealed batteries are capable of holding their charge from 6 to 12 months if they are not hooked to the scooter battery terminals. After you have fully charged them, disconnect them from your scooter. Move them to a safe area – both temperature extremities, cold and heat, shorten their life – and hold them there until you need them.

HOW TO TELL IF YOUR BATTERY IS BAD

There are a number of steps you can take to determine, with reasonably accuracy, whether your battery is indeed bad, or some other issue is at the root of your problem:

  • ​How long has the battery pack been left uncharged? Ask yourself this question. If it has been left for more than six months, it is highly likely that the battery pack has grown defective.
  • ​Charge the Battery Pack for 8 Hours: However, make sure you don’t let it charge for more than 12 hours, as in that case, there’s a real possibility of overcharging and damaging the battery pack further.
  • ​Test the Battery Charger: Plug it into a wall and look if one or more of its indicators light up. If none is lit, or if the indicators blink on and off, then the battery charger is defective.
  • ​Test the Battery pack by running the Scooter: Peform a battery test on the scooter by fully charging the battery pack and riding the scooter at full throttle on flat ground. Take note how long the battery pack lasts. Most electric scooters top out at around 45 minutes on flat ground. If the battery pack lasts less than 30 minutes, it is extremely likely that it is somewhat worn out and needs replacement. If the battery pack lasts less than 20, it is surely moderately worn out and should be replaced. And if it onl lasts 5 to 10 minutes, then you should have had it replaced yesterday.
  • ​Alternatively, if your scooter will not run, you can use a 12 Volt automobile battery load tester to perform a check on your scooter’s battery pack. All auto part stores sell these, and, in mosr cases, they will allow you to load test electric scooter batteries for free.

​TEST A BATTERY PACK’S VOLTAGE

An excellent way to to determine the stage of charge is to take a voltage reading of your scooter battery pack. Whenever a battery is reading 0 volts, it is highly likely that the battery has experienced a short circuit. If it is incapable of reaching higher than 10.5 volts when getting charged, then it is likely that the battery has a dead cell. If the battery gets fully charged, but the voltage remains at a level of 12.4 or even less, the battery is probably sulfated.

Sulfation is a byproduct of battery dischargement. By recharging a attery, the sulfation crystals will be reversed and turned back to electrolytes, capable of producing power once again. In cases where the battery remained uncharged, or severly discharged for extended periods of time, the sulfation increases in size and hardens onto the plaes. This essentially removes the required chemicals for power production. It also decreases the potential for reaching a full charge, making the battery discharge quicker than normal.

Charging a sulfated battery is analogous to washing your hands while having them covered with gloves. Charging, at this point, will not be able to restore a battery back to proper shape. In these cases, replacing the battery is recommended, as it is unlikely it can be fixed or get repaired as is.

CONCLUSION

By following these troubleshooting tips you will likely be able to determine whether your battery malfunctions or is on its way to such a state. Unfortunately, in many cases, sealed battery packs will require lengthy testing – simply looking at them will not be enough to determine if they suffer from a defect.

The tools you will need to perform these tests you can easily get from auto part store. If for any reason you are incapable of doing so, and thus unable to perform the testing at home, it might be in your best interest to consult a professional. It is important to realize that when it comes to batteries, they can reach a point of no return. In these cases, stressing over fixing them is unsound. Your best best is to replace them completely.
