Question: I plugged in my Roomba with the new battery. The charge light is pulsing red. Been like that for an hour. Did this happen to you?
Document: I should have paid attention to the negative comments before purchasing this but I gave it a shot. My mistake. Once the battery arrived I put it in my Roomba then let it go through the 16 hour charge process. Once the time was up the green light was on indicating a successful charge but once I took it off of the charge unit the light went red. I then repeated the process on my second Roomba with the same results. Just for fun I tested the battery and it only showed 10.67 volts.
I received a replacement battery for my Roomba. I charged it for 24 hours before using it. The Roomba ran for 5 minutes and then no more charge. I recharged for another 24 hours and then it wouldn't run at all. After returning it for a replacement, the company sent me a replacement within 2 weeks. I charged it for 24 hours. Even though the Roomba has a green light when it's plugged into the charger, when I take it off the charger and try to turn it on, it does not even turn on.
****UPDATED REVIEW****My Roomba developed a charging issue which I initially blamed on the first Pwr+ battery I received. Alex from Pwr+ contacted me based on my initial review of 1 star and wanted to help resolve my problem. He sent me another battery to try and the Roomba would not charge it either. The blinking red light would turn solid green after ~ 12 hours but would turn red as soon as I pressed the power button.I connected the battery to a car battery charger while monitoring the voltage to make sure I wouldn't damage the battery.
I made an informed decision when I ordered the Pwr+Extended 3ah. Still, I was anxious for the shipment to arrive. When it did, i plugged it in uninterrupted as other buyers recommended. Now, my Roomba Discovery works like it's brand new.
With a new battery from Pwr+, my Dirt Dog is running like new again. I've been using it for about 2 months with zero problems - always have it plugged in and fully charged. Now my Dirt Dog runs longer than another Roomba I have.I would not hesitate buying another battery from Pwr+ when the time comes - good battery at a good price. Delivery was fast and as advertised. No complaints here. If your Dirt Dog seems to be running a short amount of time, try giving it a boost with a new battery.
My roomba used to leave the charger with a green light, get 10 feet and turn yellow, 10 more feet it would turn orange and race back to it's base station to recharge. I got this battery and now the roomba runs like day 1 out of the box. It cleans the house for 3 hours before turning yellow now. Another 3 hours (the next day) then it turns orange and runs back home. Make sure you clean your filters and buy new brushes and bristles.
Thinking this was not an "extended period of time," the battery was left in the unit. I must say after plugging the equipment back in, I was pretty disappointed to realize even 3 days on the charger has not made a bit of difference. The battery seems to be completely dead. The Roomba will glow red and sing its sad little "I'm tired" song only when it's on the charger. Once it's removed, it's dead, Jim. No light, no musical tones.I've sent an email to Pwr+ and am hoping to hear from someone soon.
I was completely aggravated that a 2nd battery for my roomba had gone bad. I bought this battery and charged it, the roomba worked brilliantly....for 20 minutes. Then I couldn't get the battery to recharge. I tried all the 'push this button three times, hold the other one down for 15 seconds' nonsense to no avail. Boy was I unhappy.It dawned on me that the roomba worked perfectly as long as the battery had some juice, so perhaps the roomba could no longer charge batteries. Hoping I wasn't throwing good money after bad, I ordered a Pwr+ external battery charger.The external battery charger started making happy green light strobes and 2 hours later,  my roomba was zooming around like old times.
We were looking to purchase a robot cleaner, but before buying one we inherited a Roomba from a friend who had just bought a new one after the old one stopped running very long. I charged the old battery overnight and it worked, but would only hold a charge for about 30 minutes. Since the Roomba obviously worked, I decided to try a new battery. Much to my delight, the roomba now has a green light on for a looong time. It runs much much longer now. I haven't timed it, because it runs so long that I forget about it.
This is my second battery for different Roomba appliances. The first was for the Scooba. After being told by Roomba that my unit needed a new internal power device and offered to sell me a replacement Roomba for about a 30% discount from a new machine, I decided to try a new battery first. After all, it's Amazon, and if it didn't work, I could return it.Plugged in the unit, charged it, and it's been working perfectly ever since. Considering the long warranty offerec by Pwr+, I highly recommend them.When the Roomba wouldn't hold a charge any longer (it had been in storage for over a year), the first thing I did was order a new Powr battery.I now have 2 perfectly working units.
Answer: No it didn't. I charged mine over night and it has worked great ever since.
