Is it possible to recharge a Jet3 Powerchair once it has been sitting for over a year? I think it has been deeply discharged and wonder if there is any hope or if we need a new battery?? Thank you.

First be sure it is really discharged.

the type of battery these mobility scooters use do not charge if the battery gets really flat. I had a relative who had his scooter taken off him by the nursing home and they left it stored in a shed without plugging it into a charger . Once it got flat the batteries would not charge at all. If only they had left it on a float charge . https://www.everybattery.com.au/deep_cycle_battery_charging.php
"Here's the problem: Most battery chargers have built-in safety features that may prevent chargers from recharging deeply discharged batteries." for more info https://www.optimabatteries.com/en-us/support/charging/resuscitate-deeply-discharged-battery

If a lithium battery is too deeply discharged or the cells matching become unbalanced from many deep discharges, then it can be permanently damaged. The chargers often have over discharge detection circuits, which prevent you from recharging the battery under these circumstances. This is because the battery when overdischarged, could vent or overheat etc. if recharged.
Overdischarge can happen if you don't recharge the camera after using it and then leave it in the closet for a long time before trying to recharge.
This often happens with laptops if you don't remove the battery when storing it for months. The laptop uses a small amount of current even when switched off and this causes the over discharge.
Best bet is to try and charge a new battery, to see that the charger is ok.

I'm afraid that the battery you bought as new, in fact is a battery that was in the shop for years, and can't hold enough power.
If you camera works normal for one minute and does not run hot or even gets warm, I think the battery is not as good as you think.
Can't find since when the camera is around, but my guess is the camera is not that new anymore.
Please recharge the battery and use it, and than recharge it again It could take a few charge cycles, before the battery gets its full capacity, but don't expect wonders.

Rechargeable battery life is not infinite. A few houndered times is about all you get on average. How deeply you let it discharge, the temperature of the space that it is in, how long you let it charge, etc. all affect the number of charge / discharge cycles it can provide.
You should probably have the battery replaced - or if too costly, stick with direct power only.
Good luck!

All batteries have a FINITE amount of time before they can no longer hold a charge, if your battery is older then a year it is no longer covered under warranty either. Have you noticed prior to this that the battery was holding less and less of a charge? ALSO batteries do over heat and stop receiving a charge, best way to tell is to keep the laptop plugged in. unplug the battery for a minute, then plug it back in and see on your task bar if it says charging or plugged in not charging. let me know! good luck to you as well!

There is no way to revive a rechargeable battery once they go bad. Rechargeable batteries have a lifespan that is affected by how many times they have been discharged and recharged and how fully discharged they are between recharges. Most batteries will last longer if they are fully discharged before recharging and allowed to cool completely before recharging, heat being the main culprit to their longgevity. They will eventually reach a point where they will not charge anymore or if they do they will not hold a full charge for any appreciable time. The best test for the batteries ability to take a charge is to completely deplete the battery either through working it or sitting on the couch with the trigger pulled until it stops working completely, let it cool down then put it in the charger. If it charges, use it to see how long it lasts. If it dies quickly it needs to be replaced.

Welcome to FixYa.

First thing we need to verify is what type of battery are you using.

The Capacity of rechargeable Ni-MH batteries may be temporarily reduced when new, after long periods of disuse, or if they are repeatedly recharged before being fully discharged. Capacity can be increased by repeatedly discharging the batteries using the DISCHARGE option and recharging them in a battery charger. Do not use this option with non-rechargeable batteries.

Also possible reason why your battery easily discharge if:

* battery are cold
-warm the battery by placing them in your pocket or other warm place.
* ther is a dirt on the battery terminals
-clean the terminals with soft and dry cloth
* the camera is always on AUTO mode
- choose different shooting mode

I hope this information will help on your issues.

Thank you for using FixYa.

I had to re-boot my computer not long after plugging the Vibe in to add some music and recharge. When the computer rebooted it seemed to be dead.

After reading the above I pressed the reset button. It came up again.

Now, here's the crux. After it went through its language questions the recharge message said: Charging. Do not unplug. (Or similar.)

I suspect that the Vibe was deeply discharged. I haven't used it for a while and don't recall recharging it after the last use so I'm not surprised to find the battery deeply discharged.

In future I'll be more careful to read its little messages when I plug it in.

NiMH tends to have a "memory". What this means is that the batteries will get used to being only charged and discharged a certain amount. What could be happening is that the battery THINKS it is charged when it is not... or.. it THINKS it is discharged when it is not. You can try to recondition them:

1. Charge them
2. reset the charger and charge again
3. put them in your device and drain them
4. let them sit, drain them again
5. recharge them
6. drain them again

Do this a few times. If you don't notice an improvement, you may want to consider getting a new set of batteries - I would recommend lithium rechargeables.
