The Best Power Wheelchair Batteries Reviewed

Depending on your situation, it may not be possible for you to self-propel a manual wheelchair. Also, you may not want to be in a position where you do not have an attendant or caregiver around and your power wheelchair‘s batteries have died in the middle of nowhere. That would be scary, to say the least.

So, it not only matters a lot to consider battery prowess while buying a wheelchair, but it also matters a lot to know which battery to buy once your initial battery has run its life.

Or, if your wheelchair has come with a single battery, you may want to buy one as a backup (in this case, it is best to buy one that has the same characteristics as your existing wheelchair battery).

Here we have a video tutorial to give you a general idea of how to replace a power wheelchair battery.

Specifications of Batteries in a New Power Wheelchair

Best power wheelchair batteries are compact, long lasting and of course, economical!Batteries generally come in 2 configurations: 6 Ah and 10 – 15 Ah. Voltage is 12V. AH stands for ampere hours. It refers to the amount of energy your battery can store. Higher Ah rated batteries will give your power wheelchair a longer range on a full charge.

Wheelchairs which pack 6 AH (12 V) batteries, generally come with 2 batteries, connected in series to produce a 12 Ah (24 V) effect. While the ones with 10 – 15 AH battery come with a single battery, and it is advisable to buy a back up battery to increase the maximum distance that can be covered on single full charge.

What to Consider Before Buying Wheelchair Batteries

  1. Even though your new wheelchair comes with batteries of ranging from 6 to 15 AH, when you are buying a replacement battery you may buy one with a higher configuration of 30 AH – 60 AH to increase the performance of your wheelchair. This will greatly increase the maximum travel distance of your wheelchair.
  2. You have to consider the total charging time for your battery. Obviously, it cannot be taking more than 6-9 hours to fully charge. Otherwise, charging for one full night also would not be sufficient to fully charge your power wheelchair’s battery.
  3. Warranty: You should keep an eye on the length of the warranty period for the battery and should ideally avoid buying a battery with less than 1 year of warranty. Also, you may come across some batteries (and battery companies) where you will have to bear the shipping costs if you are invoking a warranty. Shipping costs to avail of warranty may be prohibitive depending on your location.
  4. Weight: The weight of the battery should not bother you till it’s is less than 10 pounds. However, for larger configurations of battery, the weight of the battery exceeds 25 pounds and that adds to the weight of your wheelchair. If you have to fold your wheelchair and lift it to the back of your car, this extra weight may be a hindrance.
  5. Dimensions of the battery: You should obviously buy a battery that will fit inside the battery box of your power wheelchair. For the most part, this should not bother you unless you are planning to buy an extra-large battery.

Pulse Chargers

Finally, this article will be incomplete if we do not briefly discuss pulse chargers. You may invest in a pulse charger or a desulfator charger that has the capability to extend the useful life of your battery or charge even presumably dead batteries.

The formation of lead sulphate on the electrodes is the principal reason for dead batteries. Pulse chargers can reduce the size of sulphate crystals formed on the electrodes or thin out sulphate layers on them. Pulse chargers are generally able to work with a wide range of batteries and fully automatic ones are easy to operate.

However, this can be a significant investment as compared to the price of a battery. It should be balanced against the idea of buying new batteries. A pulse charger will set you back by about a hundred dollars. But you will be able to quickly get good returns from it if you have multiple battery-operated devices at your home. You can read more about pulse chargers in our article about how to charge a dead wheelchair battery.

Best Practices for Good Battery Care

It is important to note that wheelchair batteries will mostly have a shorter warranty period than your wheelchair motors or body. Therefore, it is all the more important to care for them and use them properly to max out their longevity. Even then, you must have noticed that batteries hardly last more than 2 – 3 years. The following are some of the best practices you may follow to squeeze out the best performance and life from your batteries:

  1. I know that once you receive your wheelchair, you would be very impatient to get your hands on it and go on a ride. However, for the sake of your new batteries, hold on for a little while to charge them up fully. It may take up to ten to twelve hours for your power wheelchair batteries to fully charge the initial few times.
  2. In the initial two weeks of usage, you should take care to not discharge your batteries by more than thirty percent. This may restrict your activities, especially if you are using your wheelchair for your daily commute to work and do not have a car. However, you may have to take a call vis-a-vis securing a long battery life
  3. It is better to charge batteries every night for long periods (6 hours at least), even if they have not been used much during the day
  4. It is advisable to always use the charger which has come with your device. Using compatible but different chargers may reduce battery life
  5. You should not deplete your batteries by more than eighty percent.
