211 Replacement Batteries
|
Bob Wilson
Yesterday I bought a model 211 scope at the Dalton hamfest. While it works
I need to replace the batteries. He seller already has the batteries out and I assume they are bad. It works without the batteries installed but maybe it not good to run it that way. My question is what kind of batteries can I use? It came with Nicad but NiMH are common these days. If I had my choice I would like Eneloop batteries or something like that so they would hold there charge for a long time. Bob

Hi Bob,

Years ago I posted this information about the batteries I found for the model 214 which I own. With a little research comparing the battery size of your 211 to my 214 I think you will find the 211 uses the same rechargeable battery pack. If that is the case then you are in luck because this link will connect you with a company that makes an identical replacement for the Tek batteries. The cost was dirt cheap, and they were absolutely perfect plugin replacements. The quality was excellent. The new batteries ran my 214 50% longer than the specification in the Service Manual showed the original batteries were capable of. Dennis Tillman W7pF

Please share the link you mentioned so I can check out their batteries. ALSO, beware that the power supply sections of some of the "2XX" models that use these batteries will not regulate unless a good battery is installed, and will send excessive voltages to the rest of the circuitry. Thanks, Bruce KA2IVY

This is the email I wrote years ago: Note: the link is broken across 3 lines. It is very hard to find this battery pack on this site so use the link. Dennis Tillman W7pF

It's under Medical and Scientific batteries. The company that makes them is called BulbTronics. They are the ones that supplied me with the batteries for my 214 scope. The battery packs they made up were a perfect fit, very professionally made, and dirt cheap. The scope ran for over 5½ hours on them which was almost twice the Tek specification. Best thing to do is go to their web site and fill out an email request. This is the way you have to request that they make up a pack for you. It's more than a little strange but it is worth it. You will appreciate that when the batteries arrive.

I could not find the pack listed at the link you sent. But I think the 5 in line AA's is a common item. I saw some at Amazon for less than $5 each.
And my local Batteries and Bulbs store probably has them too. The original ones were probably 600MA and now they are all higher capacity. Bob

Yes, unfortunately I could not find it either.

Be careful, those are probably NiMH packs. The simple charger in the 211 will quickly ruin NiMH cells. The Bulbtronics pack is NiCd. Here's an updated link: https://www.bulbtronics.com/Search-The-Warehouse/ProductDetail.aspx?sid=0029911&pid=BAMED4149++++++&Source=SearchResults# If that doesn't work, search for 5149. They call it "Medical Battery 5149".

KeepIt SimpleStupid
Do a search for osibatteries tektronix 212. $22.00 per pack. their site is broken right at the moment I'm posting, but Google gave the $22.00 USD result.

The 211 uses the same batteries as the 212. The scope won't work without the batteries. Be aware of the charging circuit and battery modification (fuse in the pack). http://www.hakanh.com/dl/docs/kitinstructions/050-1841-00.pdf I have one scope with the kit and one without. I did install the kit some 15+ years ago in a work 212 scope. I'd love to have another kit.
