My family uses lots of bicycle lights and I need to buy some more now because they break or get lost or stolen.
I'm trying to work out whether it is better to buy the bike lights that use AA or AAA rechargeable batteries, or a bike light that has a built-in battery which needs charging via a USB cable.
I have a good battery recharger which will not only charge batteries using different modes, but will also "recondition" the batteries. This function refreshes the capacity of the battery to either take more load, or to hold it for longer (or both, I'm not sure).
I'm not sure how effective this is but I always sense that some batteries run out a lot quicker than other ones and then I put them through the recondition programme.
It strikes me that it's impossible to recondition a built-in battery because my battery charger doesn't have a USB port.
Is this something I should take into consideration when choosing my next bicycle light?
