I saw a comment about this battery having a T1 (narrow) terminal versus a T2 (wider) terminal. Does this make a difference with the installation?

Yes a little difficult to keep the connectors on when sliding the battery back in place. They sent an adaptor when i emailed them about it

I actually bought this for a relative. I just asked him that question and he said the installation was easy and it has been working fine for a few weeks now. He used it as a replacement battery for his Fios box

Unclear from their Yuasu data catalog as these specific types are not detailed by those numbers. However the pictures of this Yuasu battery on eBay shows the usual 7A, 12VDC battery with terminals on the top. The "S" designation may mean that the terminals are different in some way--perhaps on "side" or "switched" I hope this is useful. I use mine in my home security sysstem as the back-up battery in case of power loss. The plain designator of NP7-12 was the exact replacement I needed and the wires slipped right onto the battery terminals. Check what you are using the battery for as far as size and type of clips used, then check the pics on eBay and see if this is what you need.

No, slightly different size and has 3 or 4 terminals where the K20D battery has only 2. Sorry. I was hoping to use my K20D batteries too but they do not fit.

Jeff, the information in your question is confusing. The battery has the smaller terminals and your cables should match, if your cables have connectors for smaller terminal blades.

Also be sure to make sure you have your radio code if required, if you choose to disconnect the negative battery terminal while installing. Good luck

I received a battery with two F2 terminals. Thankfully, included in the box was a pair of F2-to-F1 Step-Down terminal adapters, which I then used in my system.

I bought the extra capcity battery. The higher cap batteries are approximately 3/4 inch wider than a standard battery. The standard battery would fit flush with the back of the latop. For what it's worth, the battery I purchased is working great.

I concur with Mr. Heinen: mine has F1 terminals. (Bought July 2014 from Mighty Max Battery.)

F1 and F2 represent the type of connector that is located on the top of the battery. F1 terminals are .187 inch wide (the contact towards the end narrows) and F2 terminals are .250 inch wide (the contact towards the end narrows). T1 / T2 are the mating terminal usually on the wire. They are easy to change out and can be found at a local automotive store or Radio shack.

My original UPS battery has .250 inch terminals, the replacement battery has .125 inch terminals. I simply cut off the old terminals and installed the .125 inch size. A bit annoying but easy. Of course I could have purchased the exact replacement from APC for three time the price. Or more.

NO. I suggest not buying the battery from this seller. I bought one a few months ago. I barely fits my T61 and later battery died in 2 hours.

I use this to replace a BD 4-12 (12V, 4.0Ah) battery and it is working fine. Without knowing for sure, the specs on the battery you want to replace sound like they are the same as mine was. The terminals on this type of battery are a little odd. That is what I would mainly look at. They are flat metal prongs that rise up from the top panel of the battery and then fold over horizontally. Your wires to your existing battery should have a female connector that slides onto these flat terminals. If that sounds like what you have, give it a whirl.

The UB1270 (item shown) has the wider f2 terminals (0.25 inch), but the seller may ship a functional equivalent with the narrower f1 terminals. Not a perfect connection match, but as long as the host unit isn't getting jostled a lot, the wider connector will make a sufficiently adequate connection to the battery's terminals.

The terminal sizes on the battery are the same size as opposed to your door opener butt connectors. The size difference is minimal and will work with this battery. If you choose to use this battery, you will save money. BTW, specs wise this battery is equivalent to the OEM battery.

I also had a T61 that I gave to my sister. I ordered this battery below and it worked great. I tried the other option they listed from discountbatt and it' only lasted about 45 min.

Yes - it does. If you exclude the terminals, the battery is 2.05" tall. This is measuring my UB1213 battery that's marked 1.3 AH, which I believe is an upgrade from 1.2 AH.
