I was going to try to solder bike light batteries I have that died simply because the wires broke, but that got too dicey for a clueless person like me.
I have several bike lights by different manufacturers. They all have very similar connectors on the lights/batteries/chargers…but not identical. If I recall, when I had two that were working, one of the batteries could work on both lights, but only be charged by one of the chargers, something like that.
Was this just poor workmanship, or are these connectors different and how do I know which is which if they are different? Since I can’t find much in the way of reference to the connectors, my guess is that they are supposed to be interchangeable?
The actual batteries are all the same: 18650x2 or x4, each 3.7 volt. (I don’t understand what any of that means, I just know that they are all the same kind of basic batteries that have been somehow combined) And what gives me longer life? More batteries (a 6pack of the same vs. a 2pack?) or the MAH number? (Which many people say is untrustworthy)
Some examples: (the connectors all LOOK the same as my connectors, but even my connectors are not identical, although they can be used as I described)
I have reason to be using these lights a great deal, so I would like a few batteries ready to go or a couple of really long-lasting batteries. But of course I want them to work with the lights I have…der…
