You'll have to have an expert disassemble the unit and replace the U2 & U4 MOSFETS in the charging circuit. They are a known problem. I got a Discovery 4210 with this problem and fixed it with stronger MOSFETs. Go here for the details: http://www.instructables.com/id/Roomba-400-Series-Disassembly-and-U2U4-Charging-F/

I received two batteries the same day, I charged the first all night and seen blue lights blinking and staying on. I left the battery in o/n and placed it in the Hoover LINX to no avail.So, I tried it again and this time nothing, I change it to the another so call new and it lit up ok and I charged it all night. The following day I put it in the LINX and WOW it works, this ismy favorite vacuum and started to vacuum, it lasted approx. 5-7 minutes and quit and I tried again to no avail. I originally was going to pay for both to avoid the problem, however you cameback and ask what I thought of and did they worked. The only rating I could give is -0, it was a waste of my time/effort.

That is what we did and battery would not charge after only a few months. I do not know if letting it completely discharge before recharging and not storing it in its built-in storage bracket will help. Electrolux is absolutely no help with this, nor with replacement parts or service.

The original that came with the product lasted a year or more if I remember correctly and that was with a good bit of use. I ordered another one from Roomba and it did not last but a couple of months. They sent a replacement, but the same thing happened. It sat unused for numerous months until I decided to give this company a try. So far so good but it's only been a month. So hard to tell at this point. Ask me again in a few months! Hard to beat though as it was about 1/3 the price.

I am not that technical, but I just installed the battery in my Roomba and I charge it with the Roomba charger without any problems. The first couple of times it doesn't have quite the charge I was expecting but now the Roomba will run 2 hours or more. I am very pleased with it! .

Did you ever resolve this? I have just tried to recharge my batteries after long non use - one seems to have fully discharged and unit won't come on. I stated to charge second battery and it too is discharging. I have taken it off charger in case I lose it too. Love to know your outcome.

You need to return it. Amazon promises a 3-year-life on this product. My first one lasted a little over 18 months but I used it a great deal over that time and felt that I got my money's worth. It always fully charged until it suddenly started to show a full charge but only last less than an hour. If you are having trouble with it this early then return it. I'm on my second battery now and so far it is charging and performing as it should. Hope that this helps. My second battery has lasted about 18 months also. I tried the below suggestion of the freezer and that didn't work. My feeling is that if you use the battery a great deal then it is still a decent buy as its cost is far, far less than a Panasonic made one.

I had similar experience. Try ordering a new AC adapter cord too. My battery now holds the full charge and its been 2 months and its still okay.

I have not had that problem, yet! Sometimes a battery will not receive a charge. I would buy a new battery for a cure>

Dyson has replaced my battery and various electronic parts 3 times now. And right now it still doesn't work. So I don't know what is happening with yours. They thought mine was a charging problem but it really isn't. It works just fine now as long as it has a good suction on the floor. Customer service is great. The product is great when it works. But it is an inherently flawed product.

We just had a similar incident with one of ours. we just let it run itself down till there was NO battery life left. I almost threw it out because I thought it was broken! I decided to charge it one more time to see if I could get it to work and it had reset itself and came on and worked properly. just let it go till it is dead dead dead and then try recharging it and see if that works

I charged them initially for about three hours. One of the batteries seems to take a charge overnight, but the other is pretty bad. I love the unit when it is working, but all too often, the battery goes dead without any warning. I've tried to get replacement batteries (thinking I may have a bad one), but can't find them anywhere. This is totally unacceptable! If anyone knows where to get replacements, please let me know.

I had my Roomba model 4210 for at about 7 years before I gave it away to a friend that was interested in getting one, The only thing I had to replace in the time frame was the battery a couple of times, Other then that it always worked. I purchased a newer model after I have that one away.

The battery inside the wand is not holding a charge. My first one did that after 2 years. I was told it was not a user replaceable part. I bought a new one, it works great. So if it's under warranty get in touch with Silk'n. If not look for a new one on Amazon. I got a new one in the box for $135.00. It retails for $300.00 I love it, people guess me at 15 years younger than I am.

It's a simple battery replacement in the roomba. Charges just like you would normally charge it. Make sure to charge it for a full 8 eight hours before using the first time.
