Replace iRobot Roomba Battery

I have a robot vacuum, iRobot Roomba 551. I can not recall when I bought it. But, I think it is five years old at least 4 or 5 years. I bought it at Costco. Maybe a little bit over $300 at that time.

We use it once a week for three bedrooms in my house. Two months ago, my daughters, who are responsible for vacuuming, told me that the robot does not work. It looks full charged, but run down in one minute. I think it is battery life.

When I came back from San Francisco, I checked the battery replacement vendors on Google. At last, I found one is very close my house.

It is Certified Battery. You can find almost all different battery on their website. They will ship it to your home. But for me, I would like to go there and do my local shopping.

Before I go there, I took off the battery from iRobot Roomba 551.

How to take out the battery?

It is simple. Unscrew a screw on the small yellow tuning brush., and remove it. Then, unscrew four screws and took the cover off.  It looks like below.

How to get a MagicJack adapter Replacement for free

I have a magicJack adapter. The old version. Bought in 2008. It is 6 years old.


It is not magicJack Go, or magicJack Plus. It is traditional magicJack. Work with computer.

Last month the phone jack is broken. The plastic part cracked and RJ11 phone connector can not stay in the jack properly. Tapes help.



Then the question is to get a replacement of it. I searched the support page of magicJack web site. It said $40 will be charged for cost.

Anyway, I am thinking it is reasonable for a device. The old one I got is $40 about 6 years ago.

But, I did not find the place to make an replacement order. So I started an online chat with the support.

Support staff told me that I can get a new magicJack Plus with $5.39 for shipping and handling. I am so surprised. Yes I have magicJack since 2008. I refilled my account for 10 years.

I am very happy with this deal. So I confirmed my credit card information on file. The order is made on Aug 18. And I got the new device on Aug. 21. Perfectly.

The package is simple. The guide is in the front, which show me how to transfer my existing phone number or magicJack account to the new device.


New adapter is magicJack Plus.


This one doesn’t need computer. After I setup it on the computer. I just connect it with USB power adapter, LAN connector, and phone connector.

Conclusion: Get a replacement magicJack Plus for free.

Replace the battery to extend the life of iPod Touch 3rd Generation

I have a iPod touch since 2010. It is 32GB 3rd generation iPod touch. It works all my apps I have. The speed is fine. The only problem is the battery life. I can only use it for 20 minutes, then it needs charge.

After googleing and researching, I found it is not hard to replace the battery to extend the life of iPod touch.

I ordered a replacement battery from DX.COM. This online store has a lot of small stuff which is hard to find in local market. And the price is low. Quality is OK, if you are lucky. But the shipment is slow, or very slower. This time, I wait more than one month to get it.

This is the one I received this morning.


$5.30 only.
