Tenergy Replacement Battery for iRobot 400 series Roomba 4905 Review

The Tenergy replacement battery that I purchased worked well for 7 months and then failed.Unfortunately, the warranty is only for 6 months.The vendor I purchased from (Battery Superstore) offered free shipping on my next purchase, but was firm on the 6 month warranty.

Bottom line - The Tenergy batteries seem to have short lifespans.If they typically lasted a year, I suspect the warranty would have been made to match.

HQRP APS Battery for iROBOT Roomba 500 Series Replacement plus HQRP Coaster Review

Failed after four recharge cycles.
Original 500 series NiMh battery lasted 200 full discharge cycles (cleaning two rooms once per week two years, always left on the charger between; resetting and long recharge did not revive it).This replacement charged and ran properly out of the box but for only four charges.There appears to be no warranty by the company, and after use may not be returnable to Amazon (still within 30 days and appears as refundable by Amazon, so will return it to them and see). (Was refunded -- Amazon is supplying the backup the suppliers don't do themselves, probably more efficient over-all for small items and all the shipping).
After failing does not hold a charge; the full charge light comes on after 15 minutes, and the Roomba is dead when turned on or runs 5 minutes. This is after being on the charger a week, starting with supposedly full charge. Same symptoms as with the original battery.But it worked well a few times, so the system seems intact -- the only variation is the battery.

iRobot Roomba APS 4905 Battery Review

Your Roomba may be experiencing an issue where the battery is deeply discharged and may need to charge longer than the standard 2.5 hours. (or 6 hours if you have a standard charger)

If you have fully charged your Battery (the Roomba Power light is solid green) and it charging time was short(less than 20 minutes) and its run time was short (less than 20 minutes) you will need to do the following.

Reset the Roomba charging system. Do this by removing the Battery and holding down the "power" button for at least 5 seconds. Then reinstall the Battery.

Plug the Charger into Roomba (avoid using the Home Base if you have one so as to ensure the Roomba's charging cycle is not interrupted.)

Charge the Battery until the Roomba Power light is solid green and keep the Roomba on the Charger for an additional 72 hours (3 days). Note: Do not interrupt this charging cycle.

In Max mode, run the Roomba for one complete cycle without a Home Base present, to deplete the battery. Keep track of the runtime and if it has improved, repeat steps 3 and 4 a few times. If your Roomba does not have Max mode, run several Clean cycles until Roomba stops and plays the "dead battery" song.

HQRP 3300mAh APS Battery for iROBOT Roomba 4905 Series Replacement plus HQRP Coaster Review

Our Roomba was down to running 15 minutes or so on a charge.As usual, I tried the reset procedure - which helped a little, but not much.I rebuilt a battery a couple of years ago with one of those battery pack / triangular screwdriver kits (sold here and elsewhere) which, other than taking me over an hour to remove the glued-on top, went well.I just didn't feel like messing with it this time, didn't want to pay the Roomba highway robbery price, and wanted a higher capacity battery than the OEM, so I ordered this battery.When it arrived (nicely packed BTW) I did the right thing and charged it for a few days before using it the first time.Our Roomba can now do the living room and dining room before needing a recharge, which is somewhat better than the original battery.So far so good!

HQRP 3300mAh APS Battery for iROBOT Roomba 550 / 560 / 570 / 580 [Vacuum Cleaning Robot] Replacement plus HQRP Coaster Review

The original battery pack in my Roomba 550 was able to run the vacuum for about two hours initially. After the first year, its run time has dropped to about one hour. It deteriorated quickly during the next 6 months, to the point that the vacuum can only run for 3-4 minutes before the dreaded 'I-am-dying' beep. I tried everything to revive the battery, including removing the pack and deep-discharging/charging it manually. Finally, I concluded that the battery has developed high internal resistance and cannot be rescued. That's why I ordered this item (HQRP 3300mAh APS Battery for iROBOT Roomba 550-580) last November.

There were several similar products that showed up when I searched for 'Roomba 500 replacement battery' on Amazon. This one is not the lowest-priced item, but I selected it mainly because the product description is more specific (it says the capacity is 3300mAh, which is 10% higher than the 3000mAh for original Roomba battery), and it comes with an 100-day warranty. In contrast, other cheaper battery packs (such as the iRobot R3 500 series APS Battery) don't even specify the capacity, but simply make vague claims such as "50 percent greater useful life than original Roomba batteries". Furthermore, their pictures show a plain battery pack without any brand names. So there's no telling what kind of generic battery you will receive.

I installed this HQRP battery pack upon its arrival, and my Roomba 550 powered up immediately. It was even able to run the vacuum for a few minutes before recharging. This is a good sign because it means the battery pack does not suffer from rapid-self-discharge problem like many other NiMH cells. After several charging/discharging cycles (which were necessary to bring the battery pack up to its full capacity ), my Roomba was then able to run for at least 2 hours, with the indicator light still at Orange (instead of Red). Therefore I believe the stated capacity of '3300mAh' to be accurate.

Of course, it is still too early to tell whether this replacement pack will last longer than 12 months in my Roomba. But so far, it has performed beautifully after more than 3 months, with no signs of slowing down - yet. I'll update this review if any problem turns up in the future.

[Update on June 6, 2010]:
Battery pack still going strong after 6 months.

iRobot R3 500 series 14.4V APS Battery Review

Very disappointed in this product. They describe this as an iRobot battery, and even put a picture of the iRobot battery in the product listing, however, and this should have been obvious from the price, this is NOT an iRobot battery! Now, I'm not an iRobot snob, and I would be perfectly happy with a generic replacement battery, IF IT WORKED! It holds juice, and it will power the Roomba, but upon docking with the home base, I get a one red blink error light (battery problem) and a fast red blink on the charge indicator light (never turns green after charging). I thought this could have been due to the Roomba forcing a deep recharge (16 hour cycle), but I left the Roomba on the home base for 24 hours, took it off, and the Roomba was still indicating it had no charge. I did a reset of the Roomba software (hold down the "spot" and "dock" buttons at the same time for 10 seconds), and only then did the indicator light turn green. As soon as I placed it back on the homebase however, the flashing red lights came back. It's not a problem with the Roomba either, I put the old iRobot battery back in, and the charge indicator light worked like it was supposed to. Until I get a REAL replacement, I'm stuck using my old, dying, iRobot battery... which is still better than the defective, generic battery that was sent by Battery Superstore.

Keep an eye out for an updated review. I have a message into Battery Superstore asking for a replacement of the defective battery they sent me. I will update this review with a review of their support, as well as any replacement they send out.******UPDATE******

I sent a message to the seller, via the Amazon interface, telling them of the problem with the battery. They were quick to respond, and upon answering a few of their follow up questions, they were quick to process a replacement for the defective battery. I will update this review once I receive the new battery.

******UPDATE******

The battery they sent out to replace the defective battery, is defective as well. Same problems as the first one they sent out. I will be contacting the seller again to see if possibly there was a problem with the entire lot, or if I am just extremely unlucky in the batteries they have been sending me.

****** FINAL UPDATE******

Rather than keep sending me defective batteries, the seller has agreed to refund my money. They even sent a prepaid mailing label for me to return the defective batteries.

Overall, I'm disappointed that the product did not work, but I couldn't have been happier with the customer service. I ordered an authentic iRobot battery finally, and it works perfectly.

iRobot 4905 Battery Review

I have owned a ROOMBA Discovery for about 3 years and am just now finding it necessary to replace the battery. Sure, I had major problems like many others with short battery life beginning when the unit was about 14 months old.

I did a bit of research and found a discussion group that listed a good "try this before you panic" solution. Reset the ROOMBA and refresh the battery. And it worked! How?

Run the ROOMBA until the unit stops. Let it sit for about 15 minutes and try running it again. Do this until it no longer will start up. Then, remove the battery. Flip it over and hold down the POWER button for 20-25 seconds. Release. Flip back over and insert the battery. (I also took this opportunity to thoroughly clean all of the contacts with a Q-Tip and a little rubbing alcohol - letting it dry completely before putting the battery back in). Finally, I plugged the power supply directly into the ROOMBA (not the docking station) and let it charge for 3 days.

NOTE: It may be necessary to do this 2 or 3 times (for a total of 9 days with no ROOMBA), but that time is cheaper than a replacement battery.

Magic. The battery went back to its 50+ minute running time for another 9-10 months or so. At that time I did the refresh thing again and got back to more that 40 minutes running time.

Finally, after a total of 3 refresh/reset cycles, the battery is just tuckered out and won't go longer than 8 minutes no matter what I do. And that's fine... I've had hundreds of good carpet-cleaning runs with the unit. Now, for about half the iRobot cost, I am ordering a new battery from Amazon and expect years of additional use from my ROOMBA.

So, for those who haven't tried this and find that even a new battery doesn't seem to make their ROOMBA run right, give the above a try. It not only does a refresh on the battery, it also resets the ROOMBA so it can take advantage of the power. Can't guarantee it for everyone, but it sure worked for me.
