Kitchen and Housewares Reviews of Generic iRobot Roomba Replacement Internal Battery Pack for Battery 4905. Fits Discovery, Sage, Red, and Dirt Dog Models
Customer Review: So far So good, better performance than the original Battery
Summary: 5 Stars
Got this item from amazon. The seller upgraded the order to 3400mAH for free. Like the others mentioned, you have to be carefull opening the battery as it is glued. Once it is opened then it is simple procedure of soldering the 3 connection. Write down how the layout is or better take a close up picture. SO you don't connect the black wire where the red one is supposed to go.
After the first charge (about 3-4 hours), the roomba just kept going and going for a long time. I wanted to discharge it totally before recharging it.
Great deal for 29.95
Customer Review: Tenergy battery pack for Roomba Vacuum
Summary: 5 Stars
I bought this battery pack because I wasn't completely sure the problem was with the battery and I didn't want to spent $60 bucks for a complete new battery to find out. It was a little tricky to get the old battery apart because it was glued together so I made sure I could do that before I ordered the insert by filing down an old screwdriver to fit the trianglar screws. I am very satisfied with the performance of the batterypack. After charging it worked perfectly.Customer Review: Tenergy Roomba Battery Replacement Kit
Summary: 3 Stars
Batteries were somewhat easy to replace once the plastic case opened. It seems that some of the cases are glued shut.
The replacement batteries do not have the same running time as the originals. On a full charge the Roomba runs for about 35 minutes. The unit periodically shuts down and then restarts, which was not normal with the original battery pack.
Not sure if this is due to the new batteries or another problem.
Customer Review: Definitely works
Summary: 4 Stars
I have to spend another $28 to get solder iron, solder and solder vaccum, so after all I didn't save much money, but it definitely works.
It is a little hard to open because after removing all the screws, the top is actually glued on. I tried to remove cover by force but nearly broke it. Once the top is removed, the rest is easy, just match the colors and solder the wires to the metal plate. Then put the cover back and that's it.
Customer Review: Roomba 14.4 NiCD battery pack
Summary: 1 Stars
Purchaser must be sure that the pack is compatible with their model IRobot vacuum.
Although this pack was advertised for "400 series" IRobot Vacuum cleaners, it was not compatible with my model, which uses NiMH,not NiCD battery pack.
Amazon Service took no responsibility other than refer me to Tenergy. I had to contact them, return and exchange at my expense.
