seisobs Posted December 24, 2008 Report Share Posted December 24, 2008 I dont know if this is of any help but we use Lithium batteries at work (260 of them). They last for 6 months. We have to be very careful not to get them wet as they will cook off. Jake Quote Link to comment Share on other sites More sharing options...

steve_b_wales Posted December 25, 2008 Report Share Posted December 25, 2008 My mate bought one. We used it one evening and it was good. The only down side is, you get no warning when the battery goes flat. Quote Link to comment Share on other sites More sharing options...

webber Posted December 25, 2008 Report Share Posted December 25, 2008 My mate bought one. We used it one evening and it was good. The only down side is, you get no warning when the battery goes flat. That's correct, its one of the downsides of Lithium Ion batteries. I am currently working on a range of Lithium Ion battery packs for field sports. The cells used in the currently available package are from China, make of that what you may. We shall be utilising very high quality cells as used in professional equipment. The consequence of this will be that the price will be less attractive but the cells will accept a greater number of charges before replacement is required. PW members should also be aware that Lithium Ion batteries require a different charging regime to Lead Acid. Under no circumstances should you use your bog standard charger on Lithium Ion.

Welsh Stinger Posted December 25, 2008 Report Share Posted December 25, 2008 I use lithium batteries in my night scope and they cost around £5.00 each over hear but for £8.50 I got 4 rechargable lithium batteries and the charger from Hong Kong and that included the postage , they only took 5 days to get here .

Shootingman Posted December 25, 2008 Report Share Posted December 25, 2008 I bought 1 back in Oct, & said on here how great it was, they weigh 1/7 the weight of my 17a battery which is great & lasted a full 5hr session ( approx 1 1/4hrs lamping), does this regular, BUT last Friday went out & weather changed to torrential rain, battery got damp(not soaked, just damp) 16mins later, 1 dead battery, so I think its dry weather only.

Shootingman Posted December 25, 2008 Report Share Posted December 25, 2008 Hi John, the battery comes in a canvas case, which I then had in my jacket pocket & zipped shut, as I said earlier the weather was really bad, I was soaked through but because the battery was in a case & in my pocket,it only got damp yet still died on me. Don't get me wrong, I'm not knocking the battery, its very good, very light in weight but I won't use it in wet eather again. Quote Link to comment Share on other sites More sharing options...

Baldrick Posted July 23, 2009 Report Share Posted July 23, 2009 I'd be interested in any comments about the longevity of these batteries, and whether there is any truth in the speculation about the fire risks associated with over-charging Lithium Ion batteries (see You Tube footage).

Dave-G Posted July 24, 2009 Report Share Posted July 24, 2009 I'd be interested in any comments about the longevity of these batteries, and whether there is any truth in the speculation about the fire risks associated with over-charging Lithium Ion batteries (see You Tube footage). I could be wrong but AFAIK fire risks are mainly associated with LIPO's (Lithium Polymer) rather than Lithium Ion cells. Quote Link to comment Share on other sites More sharing options...
MC Posted July 24, 2009 Report Share Posted July 24, 2009 Lipo's are a bit more sensitive than Li-ion but I wouldn't leave either of them unattended while being charged. There are some fairly sophisticated chargers around these days that monitor and balance the cells while charging them. They are a lot lighter and you can get some very high capacity ones that will last you ages. Butu as with all modern technology you pay for the privelige.

Dunkield Posted July 24, 2009 Report Share Posted July 24, 2009 Firstly I can't believe this conversation started on Christmas Eve and then carried on into Christmas day Secondly, yes there are risks with LI batteries, I won't get into naming and shaming but some major manufacturers have had massive recalls as a result. They do not like being knocked in any way, and I would never leave a LI battery charging unattended in my house. I am fairly sure Pin made a video of blowing one up just by overcharging it.

Dunkield Posted July 24, 2009 Report Share Posted July 24, 2009 John it happens a lot, but mainly to damaged cells, and normally when on charge. A nice video just for you (and of interest to anyone who uses a notebook on their lap ) http://www.youtube.com/watch?v=WeWq6rWzChw...feature=related Quote Link to comment Share on other sites More sharing options...

Dunkield Posted July 24, 2009 Report Share Posted July 24, 2009 They are only potentially dangerous, if mis-used the major manufacturers will always stress that. Notebooks (not laptops ) have had them in for years, they are generally fine if you don't mistreat them. Think of how much fuel you can get in a cars tank, it is only dangerous when something goes wrong. Quote Link to comment Share on other sites More sharing options...
