Bobba Posted October 20, 2016 Report Share Posted October 20, 2016 My Ludicrous-Lumens IR torch came with a UniqueFire rechargeable battery- UF 18650 3.7v Li-on. Fully charged I used it last night sweeping fields as I strolled the farm (the torch is used to support a 3 1/2 " screen mini spotter mounted on a 410 shotgun). The battery was certainly not in constant use but after about 2 hours switching off and on it died. (Fortunately I had a spare battery). Does anyone know whether this particular battery has a short usage time? Or perhaps I have a rogue battery? Advice welcomed. Quote Link to comment Share on other sites More sharing options...

Most batteries with the word 'fire' named on them are generally not the best. You would be better off buying a different brand.Nitecore make a good one. Get ones that are protected and be aware of the many fakes that are sold. Quote Link to comment Share on other sites More sharing options...

oldypigeonpopper Posted October 24, 2016 Report Share Posted October 24, 2016 (edited) hello, i just tested 3 makes of 18650s 1 x uniquefire 1 x ultrafire and a cheapo called GIF £3.50 for 4, all fully charged and put in torch until battery drained, the 2 unique/ultra lasted a full 2 hours the cheapo 1.5 hours, intermittant use will have a longer time. there is always 4/6 spare batteries in my shooting bag, note the uniquefire was purchased from ludicrous lumins Edited October 24, 2016 by oldypigeonpopper Quote Link to comment Share on other sites More sharing options...

Advice welcomed. hello bobba, check out my post but i think that is the norm for the cheaper type 18650s even worse with the GIFs i purchased, if you want to try some uniques to compare i can send you ?

clakk Posted October 24, 2016 Report Share Posted October 24, 2016 Totally agree with Dave get some old laptop battery,s and take them apart .Theyre far better quality than any "fire" brand and always carry a couple of spares .Panasonic,s are supposed to be the best lasting quality batteries to buy stand alone but theyre not cheap ,laptop batteries are designed to last years so usually give good service life atb Quote Link to comment Share on other sites More sharing options...
fizzbangwhallop Posted October 24, 2016 Report Share Posted October 24, 2016 I'd give Andy at LL a call and ask him what he thinks... helpful guy. I've always bought my 18650's from Torchy the Battery Boy aka big_f_d_d on fleabay (A search on Torchy will bring up his ads)... never had a problem and his stuff is genuine.

Bobba Posted October 25, 2016 Author Report Share Posted October 25, 2016 Thanks one and all for offers and advice. Have sourced two 18650s which look similar to those in Dave-G's photo. From now on I will carry spares at night - lesson learnt. Quote Link to comment Share on other sites More sharing options...
