The battery is lasting 5 minutes after a long recharge. had the machine 7 months. It used to be good. How can we extend the run time

Hello, Janrt -

Depending upon how old the vacuum cleaner is, the rechargeable battery may need to be replaced so that the battery will hold a charge longer than it does now.

Rechargeable batteries do not last forever.

You will need to find the right replacement rechargeable battery for your vacuum cleaner. The web site for the maker of your vacuum may offer the right replacement batteries for sale.

Note: I have found that some replacement rechargeable batteries for some items cost more than the price of purchasing a replacement appliance.

Best wishes.

To extend Roomba's battery life and keep Roomba cleaning at peak performance: • Always keep Roomba plugged in when not in use. • Recharge Roomba as soon as possible. Waiting several days to recharge Roomba can damage the battery. • For storage off the charger, remove the battery from Roomba and store in a cool, dry place. • Blue or black batteries should be stored after Roomba has been used. • Yellow batteries should be stored after being fully charged.
16-Hour Refresh Charge If Roomba has been left off the charger for an extended period, Roomba will initiate a special 16-hour charge cycle. This extensive charge refreshes Roomba's battery and extends the battery life. While charging, Roomba's "Clean" button will pulse quickly. Note: For best results, do not interrupt this Refresh Charge.

batteries do have a life. its probably reached its end, sad to say. if the battery can be removed, i would attempt to find a replacement.

hi right to be honest both ways are correct, but if your using it every day then its best to put it back on the charger after every use, but the problem with this is that the battery never goes totally flat, so never does a full recharge this reduces the life of the battery by upto 50% so if you are using it regular and need it charged daily then its best to once a month let the battery go totally flat so that it wont even make a sound then do a full recharge.
Doing this will ensure the battery remains at peak performance and make it last longer.

If how ever your only using it say once a week then its best to only charge after the battery has gone flat due to the fact that it would remain on charge longer and cause the battery to over heat reducing the life span of the battery.

But witch ever method you use always let the battery go totally flat once a month then do full recharge this will prolong the life of the battery and ensure it keeps working at full power.

Let me know if you have further questions ok

If it runs on NiCad batteries it probably has programmed batteries which can happen, best solution, get new battery, and use til dead before recharge, every time.

Likely your battery has failed and you need to replace the unit. If you have test meter you can test the charger output to see if it matches the rating on the outside of the case, Rechargeable batteries fail from being dropped, or charged continually especially if they are not run down to zero before recharging. You can try to drain the battery fully then recharge overnight as a test.

NiCD and LiOn batteries have this tendency. They work great for a year, then slowly die off. The problem is you. When new, the device MUST be charged for 14hr nonstop, then every 2-3 months run dead, and recharged again 14hrs nonstop. This is done so the CPU of the Roomba (cool toy) KNOWS what DEAD is and what FULL is. It does this by measuring the amount of currrent flowing thru a very precise resistance. If you do hit and miss charge cycles of the roomba or leave it charging too long, it either develops a flase memory of the above two conditions, or gets HOT and the electrolyte paste dries out. Fix is to wear it out, charge 14hrs, wer it out againand repeat 3-4x. Then recharge and use. If that doesn't fix it, the batteries are too dried and need to be replaced.

DUST BUSTER 7.2 POWER LASTS FOR
Posted by bettedxx on July 31, 2008
DUST BUSTER 7.2 -- POWER LASTS FOR UNDER ONE MINUTE??
Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. The problem that people have with dustbusters is that when they 1st get them they need to say train the dustbusters to extend the battery life, the process is simple – when you 1st buy the dustbuster then you charge it up the 1st time and then you turn it on and drain the battery down to nothing, and then recharge the dustbusters again, and by doing that you have a larger battery life and it will run longer – but dustbuster and vacuums like that do not tell you and when people buy the item they just turn it on for a minute or two and then the battery does not get a “memory” as per how long it should run. By doing this the dustbuster will last and run longer and will have fewer problems. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
Thanks, Don the Vac Man

The best for the battery if (NiMH). Discharge completly, than charge full (charge more even the charger indicates full charge)

Clean every part, maybe a hair slow down the wheels and thats why need more power.

Here some tip from the web:


With proper care, one iRobot Roomba battery can last for hundreds of cleaning cycles before you need to replace it. Here are some things you can do to extend Roomba's battery life and keep Roomba cleaning at peak performance:



Use your Roomba frequently. Your Roomba is powered by a rechargeable nickel metal hydride (NiMH) battery, which lasts the longest when you use it regularly.



Keep the brushes clean. If the brushes and brush axles get clogged with hair and other debris, your Roomba will strain to spin them, using more battery power than normal. In extreme cases, the battery can even be damaged. See How to remove and clean Roomba's brushes



Keep your Roomba plugged in when not in use. If you have a Home Base®, keep your Roomba docked in the Home Base and plugged into the charging brick. If you don’t have a Home Base, keep your Roomba plugged into the APS Fast Charger.



Make sure you are charging your Roomba correctly. When your Roomba is plugged in correctly, the solid green light should be illuminated on the charger or on the Home Base.



Plug your Roomba in as soon as possible after using Max Mode. Leaving your Roomba unplugged for more than 24 hours can damage the battery.



Place your Roomba and the Home Base on a smooth, hard surface when yourRoomba is plugged in. Make sure your Roomba and the Home Base have plenty of space for ventilation. Do not charge your Roomba on a carpet or rug.



Charge and store your Roomba in a cool, dry place. Keep your Roomba out of direct sunlight and away from sources of heat such as windows, radiators, heating vents, and large appliances.



Remove the battery when not using your Roomba for a long period of time. If you will not be using your Roomba for more than a few weeks, fully charge the battery, remove it, and store it in a cool, dry place. When you want to use your Roomba again, insert the battery and fully charge it. Leaving your Roomba plugged in for weeks when it is not being used can damage the battery.

You can purchase a second battery or replacement online at the iRobot Store.
