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 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.
