With my new Tivo I am getting maybe 2 days from the batteries (my existing ones are 3+ years old). Where can I buy new batteries?


Steve

where are you located?

Here is how you do it. Needless-to-say, it you don't have the skills, don't do it. The risk is yours!

1)Take an Xacto knife and run it along the long sides of the battery container to cut the 6 dots of glue that hold the cover on. You can also use a small screwdriver. The plastic is pretty flexible.
2)You will see 4 pink NiMCa rectangular batteries wired in series with a fuse on the bottom. Lift the battery pack up and cut the tabs attached to the bottom cover close to the batteries. Mark the tabs + and - so you wire in the new set correctly. You can desolder the fuse link if you wish and reuse it.
3)The batteries you removed are Toshiba F3's which no one seems to have for sale. Their EXACT replacement is Sanyo TH900F5 (1.2V)You will need 4 of them per TT2 battery pack you wish to replace.You can get them at Battery Tech([email protected]) 800-442-4275. They will even solder up the packs with the fuse link if you wish.Those of you on Long Island NY can pick them up. They are located in Hicksville.
4)Solder the new batteries to the tabs you cut earlier and pay attention to the polarity. Keep your soldering pencil away from the batteries.
5)You can glue the cover back on or use electrical tape to hold the cover on if you wish. Now charge the pack up and you are good to go!

I am on Long Island. If I send Battery Tech the battery they will do the replacement? (of course I can only send 1 batery at a time!)

I removed one battery assembly from inside the container that goes into the charger and brought it to them. I had them make up two battery assemblys. I replaced the batteries, charged it up and put it into the TT2 to make sure it worked well. I them took apart the second container and replaced the batteries. I doubt that they will remove the batteries for you but it doesn't hurt to ask them. Call the number above.

What is the difference in price between buying the batteries and installing them versus a new battery pack from rti?

A T2 battery pack lists for around $60.

I callede the number to Battery Tech. They didn't know what I was talking about? He checked his cross refrence to the Sanyo TH900F5 number and said he didn't have or couldn't find the battery? I'm not sure if he couldn't find it or just didn't want to look any harder. Would there be a name of a guy that you talked with? Thanks!

I live on Long Island so I went to their place with the battery pack removed from the case. The receptionist took it to the back and returned to tell me it would cost $20/pack. I had them make up two packs with the fuse link. They work perfectly. Have no idea for their response. The company primarily makes up battery packs for industry and emergency service groups(walkie-talkies, etc.).

To anyone still looking for replacement batteries you can find a 900mAh sanyo replacement with the current sanyo part number of HF-E5U prismatic battery. I checked and double checked the dimensions and they work. If you follow Toad211's instructions you should be good. However now that I have found the battery with the proper dimensions it's been difficult finding someone who has stock. Apparently Sanyo will only accept orders in the many thousands from their distributors for this battery. So good luck. I'm checking with Dantona currently but they haven't gotten back to me. The GP8M is a very close match as well but I haven't actually gotten my hands on one to see if the dimensions will work. You can get those in small quantities from battery connection at 800-817-0526
