9v battery protective cap

[Jim]

Trying to find similar in the UK: anyone any idea if anyone sells them - other than ebay plus postage of course

[charles]

why not just buy a battery connector ansd cut the leads off?

Another UK supplier

Amazon reviews say they don't fit very well and fall off.

Some battery manufactures only fit a small plastic cap over one terminal to prevent accidental shorting.

why not just take the connector plate off an old battery and cover the plate back with epoxy?

[Dave Plowman (News)]

Yes- Duracell Pro used to come with them. Threw them away by the hundred. ;-)

[Robin]

Masking tape works for me

[Max Demian]

Is that for PP3 batteries? It doesn't say; there is more than one kind of 9V battery with clip on connectors.

[Mike Clarke]

The dimensions on their datasheet match PP3

Looks like the perfect job for a 3D printer. ;-)

I bet it would cost more than the battery

I bet it would cost less than the 12p each. ;-)

But I guess it depends on how you factor such things. eg. Do you amortise the price of the kitchen and all the appliances you use when you cook a meal?

I wouldn't have bought (built) the printer to print a PP3 cap but could (easily since Mark provided the dimensions ) and do so cheaply now I have. Filament is roughly £15 quid / kg and the electricity wouldn't run to much for something that small.

Just solder a wire across the terminals and cut it when you want to use the battery. Easy.

Cheers

[Dave Plowman (News)]

Hard work, that. Just clip two batteries together.

[Graham.]

Why does that sound plausible as well as ridiculous?

Oh I know, that's what they did to moving-coil multi meters to protect them during shipping.

I once had an argument with the proprietor of an electronics shop when I tried to return a faulty meter, they said I had invalidated the warranty by opening it and snipping the wire.

[Andy Burns]

Or 244 of them...

[alan_m]

Why didn't he test them the traditional way by placing both terminals across his tongue?

[Bill Wright]

The ones made from solid brass are very good.

When I wanted to buy a 1289 cycle-lamp battery I would just ask for a "flat battery"

[Rob Morley]

I just wrap a couple of turns of PVC tape around the battery.

[whisky-dave]

I would, which is why I haven't brought a high end coffee machine for me in stant is good enough I'm glad I don't apprieciate fine coffees or wines. If I had a PP3 battery at home that needed protecting I;d stick a bit of i nsulation tape over the terminals, or find the tops at work from the boxes of 10 PP3s we buy, and with a bit (a lot) of luck I'll find the safe place where I put those rubber cap tops which I knew would be useful in the futu re.

Do you factor in your time too, that is one thing our students don't think of.

How long do you think it would take you to design such a thing ? For sucha small thing I'm not sure you're average 3D printer would print a ccuratly enough for a snug fit, would be fun trying it.
