Battery runs out in less than 60 min, used to go for hours.
My dad's wheelchair is running out of battery after a short 40 minute ride. We used to be able to go for 60 minute walks for 5 or 6 days before it even was down to the red lights on the meter. Now it runs out fast on a full charge, the red lights begin blinking at around 35 minutes, what's going on ? If it needs a new battery can I change it myself? The chair is apx. 6 years old and gets no use during the winter and maybe 60 minutes a day 3 or 4 times a week in the summer. It's his only way to get outside and it's very important. It's model P-220.

Hi. With batteries it is very important to recharge them after each use, overnight. I have seen batteries last 7 years in a mobility scooter, because the batteries were charged properly. Batteries store electrical energy by means of a cemical reaction, and if left in a discharged condition for too long, damage is done to the internal plates of the battery.
Batteries are designed to do so many charge cycles.
If a battery is run down to 75% or more, you will not get many cycles out of it. If you only run it down by 25%, you will get 100's of charge cycles out of it.
I would say that you will need to purchase new batteries for it.
When changing the batteries, change one completely first, and then the other. This way you will be less likely to mix up the wires.
Red is positive, and black is negative.
Good luck. Neil.

Hi, How long does it run? Typically you should get at least 45 min of run time out a fully charged battery. If it's slowing gradually and dying in just a few minutes its the battery. If it's goign full speed and then stopping suddenly, it's probably the thermal breaker located in the shift mechanism.
Check if the charging system works ok. At idle with lights off, you should see 13.5-14.5V on battery's terminals and 0.5V less with high beams on, at idle speed as well as at 4000rpm. Use a fresh good verified battery to take the readings.
How Long Does the Nokia E65 battery REALLY last? Ever wonder how long the phone battery actually lasts? For the first use of my Nokia E65, I charged the phone for 24 hours after receiving it (still not sure if this is necessary), then took it off the charger Saturday afternoon. The battery low warning first sounded 54 hours later. This was after
•Calls: Around 15 calls made and about 3 calls received, with almost 40 minutes call duration in total. •Data: 726kb data sent and 3.96mb downloaded •WIFI: About 20 minutes of WIFI use •Applications: Use of Skype and Gmail application as well as a bit of Nokia Maps and Google Maps The battery eventually gave up after 2 more hourse of standby. The Nokia website says the following about the Nokia E65 battery:
•BP-4L 1500 mAh Li-Po standard battery •Talk time (maximum): GSM up to 11 hours; WCDMA up to 4h 40 min •Standby time (maximum): GSM up to 18 days; WCDMA up to 20 days;WLAN idle up to 170 hours
If you are wanting to make comparisons with the Nokia E71 battery life, this is what the Nokia website claims for the Nokia E71. The Nokia E65 and E71 both use the same battery - BP-4L 1500 mAh Li-Po battery but E71 is slightly more demanding on the battery life.
•Talk time:- GSM up to 10 h 30 min- WCDMA up to 4 h 30 min •Standby time:- GSM up to 17 days- WCDMA up to 20 days- WLAN idle up to 166 hours If you are willing to help, maybe you can do the same experiment for your Nokia E65. Use the call logs and the data counter under "Connectivity" and measure how long your Nokia E63 battery lasts with "normal" usage. Report your findings in the comments below and someone just as curious as you googling battery life E65 will also benefit from your efforts.
Your mobile habits may not be as demanding as me but I hope this helped you in your battery life calculations for the Nokia E65.
To charge a battery from empty to full, it took 2 hours and 40 minutes
....... If you are willing to help, maybe you can do the same experiment ... It lasts me about 40 hours before I get a battery low warning .... I got my Nokia E65
Hi and Welcome to FixYa, I am Kelly. You did not mention the age of this scooter or an estimate of the hours it was used. This sounds like the plates in the battery have deteriorated to the point that the battery must be replaced. Old batteries will self discharge do to corrosion or multiple re-charge residue that causes internal battery plate shorts or there is no longer enough plate material to provide the amperage necessary to operate your scooters motor. The only remedy is to replace the battery. If it is relatively new... then there can be a short in the chassis wiring. I doubt there is a short in the wiring as the controls seem to be functioning normally per your comments.
I have over 40 years of real world battery experience autos, aircraft, battery packs et al. This just sounds like the battery life has been reached and the battery needs replaced.
With power wheelchairs letting the batteries sit for 4 months without charging them leads to early battery death. The lead plates inside the battery sulfate over time and the battery discharges. If the batteries were fairly new (less than 1 year) before they sat for 4 months they can be resurrected and recharged but may not hold a charge very well. Distance traveled will be very reduced. You can try removing the dead batteries from the wheelchair and charge each individually with a 12 volt battery charger set to deep cycle. You will be able to see if the batteries come back up to full charge and do not burn. They cannot be recharged easily or safely inside the equipment and the charger that came with your equipment will not turn on. They should be removed from the wheelchair first. If the batteries take a charge and the PWC runs plan on using your power chair charger on them for at least 12 to 20 hours to bring the charge back up. Test the batteries over a short distance so you don't get stuck far from home. If you don't get very far before the batteries quit, invest in some new ones. Hope this helps.
Unfortunatly, it sounds like your batteries will not take a full charge need to be replaced.
The batteries contain a gel that needs to have current run through it on a regular basis (at least 8 hours once a week) or it will solidify. If you attach the charger, what will most likely happen is the green light will either stay green or go to green after a very short time. The charger will indicate the batteries are full, but instead of being full of pwer, they are full of crud. Since you are the second owner, the repairs are up to you. You can probably find compatible replacement batteries from Interstate Batteries, Batteries Plus or Battery Warehouse. Good luck!
Absolutely not. Higher amphour batts don't put out more voltage, just more voltage longer.
The 2800 takes U-1 gel cell batts that run about 33 amphours...good for about 12-16 miles. You might be able to fit bigger batts in it, but measure first before you buy...gel batts are pricey.
