lithium batteries wont last long in my browning black ice light, why?

I don't know if you're saying they don't last as long as the manufacturer says they should or just that they don't last long, but: the xenon bulbs use a lot of power, about 5 watts compared to the LED's 1 watt. Lithium battery lifetime is given as 2 hours with xenon bulb. See the ref. for the specs.

One of the latest(?) engineering breakthroughs is the nanotechnology Lithium Titinate battery material that promises to revolutionize portable power.  It is expect that golf carts using this material will recharge in about three minutes and last about three times longer and operate at much lower temperatures without to much lost performance.  Also the nano material will avoid explosions that non-nano material risks in large batteries.  The batteries will also power vehicles and hand tools and last perhaps ten years.

That's the reason. It's old.  Batteries don't last forever. Sounds like you need a new one.

You sure do need help....\nWhen you were cutting the LED off, you created a short circuit, first with the wire cutter (or whatever you were using), and then you most likely allowed the 2 lose wires to touch each other (or both touch a common metallic item).\nYour battery is now kaput !  They don't like short circuits, you know....

The cold is hard on the battery.

How does the chemistry of a dry cell battery affect it's voltage yield..\n\nget 2 or 3 types of dry cell batteries, (as in alkaline/nickel, not AA or AAA) research on the chemistry and stuff of it, get 2 or 3 flashlights or something that can use up the batteries, and a voltage meter.\n\nsee which battery runs out fastest (keep the flashlight or whatever you use on 24/7).

"A better battery? A better mousetrap." \n\n"Every laptop and cell phone owner I know wants more battery time.  If it works as advertised, we'll soon see laptops with 10 hour batteries."\n\n"Saphion technology is superior because Saphion technology possesses safety and excellent cost/performance characteristics that cathode materials currently used in Lithium-ion batteries do not."

The best way to make it last longest is to make sure you let the battery drain.  Fully recharge it and use it until it is completley drained.  Just do that over and over and it should last a long time.  \n\nMany Ni-Cd and rechargables in general will last longer if you cycle up and down.  \n\nDo NOT always leave it at low power and try not to always leave it fully charged.

No real methods.  They are NiMh (nickel-metal-hydride) and very resiliant.  They are generally good for about 600-700 charge cycles before they start to break down.  Just the nature of batteries.

Just stick it on the charger.  How long do you think it is going to last anyway?  The batteries will keep it going fine like that for 5 years.  \n\nWhat does it matter if it lasts a week or 10 mins when you only brush your teeth for 2 min?

There's several options really. Could just be a battery issue, a memory issue, maybe something in there fried (which sadly is the most likely). Honestly though, I would recommend taking it in to the place where you bought it/ calling the manufacturer to find out, provided it's not adressed in the owners manual. They'd know, where-as we can only make half-assed geusses.

It may be related to the humidity in the air and the contact interface.  If you have some batteries of this type, try them in a humid room like the bath.  Let the batteries and device sit out in the humidity for 30 minutes or so.

CMOS battery is dead.  Just replace it with the same type.  Little coin battery on the motherboard.\n\nEdit -  these are watch batteries easily found at the nearest drug store.

lithium batteries are better in any electronic, they don't have to be totally drained before recharging them.

Because they have a low atomic number Li (Z=3) Be (Z=4). Theoretically, they should give one electron in the case of Li and 2 electrons in the case of Be giving rise to ions Li+ and Be ++. But since their small sises the electron are attached to the nucleus and difficult to remove. So , the lithium ha so their properties than the other alkali metals

Make sure you put them in right....then try some different batteries if it still is not working.

yes they will hold a charge longer.  batteries natually burn off a small amount of energy due to an imperfect storage method.  putting them in a colder environment slows down the chemical reaction responsible for this.
