What are the differences between wet and gel batteries for use in my electric wheelchair?
Wet batteries will require you to add distilled water about once every two months. Wet batteries can be damaged permanently if the water level falls below the level of the battery plates. Adding water is quite difficult for the wheelchair user because wet batteries are heavy and difficult to reach, so it usually requires the help of a second person.
Gel batteries don't require water, so they eliminate corrosion. The main disadvantage of gel batteries is that they usually cost more and have about 10 to 20% less capacity than wet batteries do.
To add to the solution, You should get sealed batteries to prevent the " water " level problem, and the sealed batteries vs the Gel batteries? Gel is more for approved for airports etc. They have been approved by HomeLand Security as not being a risk to travel by commercial means.

What are the differences between wet and gel batteries for use in my electric wheelchair?
Gel batteries are sealed batteries that have a gelled acid instead of a non-gelled acid. This is for the safety of the user, as well as a requirement for taking the chair on public transportation such as an airplane. If the chair is upset, the battery acid won't leak out which could prove disastrous to navigation and wiring systems in an airplane. By the same token, if you were to somehow flip your chair in your home and it landed atop you, the acid won't leak out onto your person.
The batteries take longer to make as the casing must be sealed air-tight, then a vacuum is applied to the casing and the gel-acid is injected so the casing is at normal pressure inside and out. That's why they cost more than non-sealed deep cycle batteries.

You should never use wet cell batteries, repeat never! only deep cycle glass mat or gel, interstate and MK both manufacture good batteries. my opinion is MK batteries are the superior by far. get the right battery for your chair. acid from a wet battery will eventually corrode the electronics and you can get in the thousands of dollars for that kind of repair, secondly deep cycle batteries charge differently and DISCHARGE differently than wet cell, depending on your usage you'd waste money, i have been doing repairs for 15 years now and NEVER put wet cells in a chair, not to mention the minor risk of explosion, minor risk, but still a risk.
It's 50/50 gel is better in getting on a plain and water has more power whatever your life needs is what you should grt
SOURCE: My Drive Cirrus Plus power wheelchair doesnt move,
The Drive Cirrus Plus power wheelchair is a folding frame chair with a VSI controller. The VSI controller (joystick) will indicate a fault code when it detects a problem with your power chair. It is manufactured by a company called Penny Giles Drive Technology. An LED flash code of 2 on the battery display indicates that the left motor is disconnected. There may be a brake fault also. The left motor can be disconnected at the plug where the VSI harness plugs into the motor plug. The pins for the motor or VSI output may be pushed back in the connector or not making contact due to corrosion or dirt. Unplug this connector and inspect the pins and make sure they are making good contact and are clean. Spray contact cleaner on the contacts to clean or re-orient the pins to make better contact. The folding frame of the chair may have dislodged the connector. The wiring harness from the motor may be pinched or cut. The brake wires and pins may have become disconnected also. The brake lever may be in the disengaged freewheel position causing a fault, so put the brake lever in the correct position. Strictly speaking, this fault code is for the motor only, but always check the motor/ brake assembly since the wiring runs from the same plug. A certified technician will have a hand held programmer to read the computer (VSI) fault log and determine the number of error codes for the various components. Using a digital voltmeter you can check the motor at the plug. The two large wires on this 4 pin plug go to the motor; the two small wires go to the brake. On the resistance scale the motor should read between 0 and 1.6 ohms. The brake should read between 30 to 60 ohms. There is a chance that the output of the VSI controller is bad. To test this swap the left and right motor output connectors from the VSI. If the error code now indicates right motor disconnected (flash code 4) you have a good VSI and bad left motor. Swap the leads back after you are done with this test. Try blocking up the chair and see if the motor runs with no load on it or after spinning the drive wheel by hand. You can also inspect the motor brushes for burning and wear. If you pull the brushes, do this carefully and blow out the dust from the motor armature. This may allow the motor to work again for a short time. You will probably need to hire a technician if, after checking for bad connections and the brake lever in the wrong position, you still have problems. I like to replace the brake/ motor/ gearbox as a complete assembly to avoid future problems. Labor for the diagnosis and reading the fault code log with a hand held programmer should be under 1 hour. A return visit to replace the motor brake gearbox is under 1 hour. Hope this helps.
