It depends - some lights have been shown to work with LiIons even though the manufacturer says they do not. In many ways this may be so as to stop the light from being destroyed if you accidentally use an AA or AAA size LiIon in light, which will have a higher voltage than the standard AA or AAA battery. e.g. Thrunite TiSome ofcourse will just burn out if you do that.It does not mean that this will not affect the health of the light, sooner or later. With lower voltage than the suggested I can not see an issue, apart from the light cutting down on its output, since it is detecting/assuming that the battery is just going flat. I suggest you search in BLF or CPF before you take any risk
Did I suggest that he should use them?
I am just speaking back to the original post and asking a legitimate question about it.Sorry if my quoting your post caused confusion about this.Quote from: dks on March 01, 2018, 02:19:00 PMDid I suggest that he should use them?
