Use the dropdown menu above to select battery or battery and kit.
You can order the battery by itself, or the better deal is the battery and the kit as it is the cheapest battery of this type and Tadiran brand on Ebay since it's a bundle and we can save on shipping.
If you don't buy the kit, you will need to get your own holder as these per the picture don't have solder tabs and you should never solder a battery.
These are 1/2 AA 3.6V batteries from a large reputable US electronics house.
This is probably the best kit you can get without soldering.
The wires are push/twist connected to the battery leads on the board. VERY secure and should not come off by accident like other kits that use clips etc.
OR:
You could also clip the battery leads then solder just the battery holder to them and bend it over so it does not overhang the board (I think it's all long enough), or solder the wires to the clipped leads.
FAQ:
1. Q: Why don't you include tape/zip ties/etc.? A: Because there are several solutions for mounting and we don't want to include pieces people won't use. I prefer a twist tie like the kind that comes on your bread to secure my wires and battery alongside the power cable, well out of the way. You might like zip ties. Those are all common household items. The parts we include are the more difficult pieces to get the right size (wire ends) and in small quantities. (Wires and Battery holder.) The hard part's done.
2. Why don't you use a 3 AA battery holder? A: Those are WAY more likely to leak and destroy stuff. I've seen the lithium batteries at ZERO voltage, under one volt, etc. that are 20+ years old and didn't leak. AA batteries? NO WAY.
Instructions:
Remove the power supply: Unplug it from the outlet power, then the motherboard. There's a tab at the front of the power supply that you pull slightly then lift the power supply out.
Take a pic before you start to confirm battery polarity but the motherboard should be marked.
Simply cut the battery leads as close as you can to the battery. Hold that lead with a small pair of tweezers, needle nose pliers, or just support the wire with a small flat blade screwdriver. Then push the red wire on the positive side, and the black wire on the negative side while twisting gently back and forth. The wire will go in and be very secure. It's a tight fit. If you forget, the + and - sides (should be) silkscreened on the motherboard.
The leads on the battery holder are long, if you like, you may trim them about 1/8 inch if you want it to look a little neater. Push and turn gently to connect the wires to the holder. The leads only go so far into the wire.
If it's easier, connect the wires first to the motherboard. If you want to remove the wires from the holder, pull on the plastic black part, not the wire! Wiggle it gently and it should come off. It's also a very tight fit.
Mount it how you like. I prefer using zip ties or twist ties and putting it alongside the power wires. You could probably simply lay it in the empty space besides the motherboard, tape it under the power supply with regular tape or double sided, etc.
That's it. Very simple!
