In contrast, the life of the 1.5V rechargeable lithium battery depends on battery cells. T his will inevitably shorten the battery life. On the other hand, although many manufacturers promise that their NiMH batteries can be used 500 times, due to the memory effect, you need to charge and discharge the battery from time to time to release the capacity of the batter y. Small amount of charge and discharge can even reduce the loss of the battery. You can charge and discharge your lithium battery at any time. There is no such concern in using lithium batteries. If the traditional nickel-metal hydride battery is not deeply discharged for a long time, the battery capacity will become smaller and smaller, and the battery life will also be greatly reduced. that use this battery will also maintain stable performance. But the discharge current of the 1.2V rechargeable battery and disposible alkaline battery will gradually decreases during use, just as the following picture shows.Ĭompared with NiMH batteries, lithium batteries have no memory effect, which is a great breakthrough. In this straight line, due to the constant voltage, the devices such as racing cars, remote controls, electric toys, etc. In contrast, the output of the 1.5V rechargeable lithium battery is a constant voltage of 1.5V, and its discharge voltage can be simply understood as a horizontal straight line. So, how do these new 1.5V batteries perform compared to NiMH batteries and disposable alkaline batteries? Let's take a look. Its principle is a 3.6/3.7V lithium battery be stepped down to a 1.5V constant voltage output through a built-in circuit module. In recent years, a new battery - 1.5V rechargeable lithium ion battery has appeared on the market. However, a lthough NiMH rechargeable batteries are comparable to lithium-ion batteries in terms of cycle times and memory effects, the standard voltage of 1.2V cannot play strength on some devices with higher voltage requirements, and only disposable alkaline batteries can be selected. So it will be a good solution provided that the current is not too high when the battery is fully charged.Traditional AA/AAA rechargeable batteries have always been the world of NiMH batteries, especially the appearance of Eneloop. The exhausted NimH will be the same as 3 x 1.33V Alkalines - still rather unused. The fresh 4 x NimH will be somewhat hotter than the new Alkalines. When the batteries are discharged below half capacity Alkalines may have high internal impedance and voltage may drop more under load than expected.Ĥ x NimH: 4V to 4.8V (slightly more at very start). If you are happy to change battery packs you could use 4 x AA NimH plus an extra series resistor or (best) a current regulator. The difference will be noticeable but probably not vast. A NimH battery in heating use will give about 1.1V for most of the discharge period. Reputable NimH AA are available up to 2500 mAh and PERHAPS slightly more.Īn Alkaline battery is about 1.55V when new but drops rapidly to 1.3-1.4V range and then drops with use to about 1V. Batteries of lower capacity with 3800 mAh labels may exist. Note that 3800 mAh AA rechargeable batteries do not exist. If the battery pack just connects to the gloves, with a resistive heating element in the gloves, then the rechargeable batteries will work "well enough". Putting heat at the source is the only thing that works, and I can't use mittens with heat packs as I need full finger control. I have Raynaud's Phenomena so no matter how effective regular gloves are, once my brain signals that it's cold, the hands will go ice cold and stay that way. Whereas the rechargeable batteries and charger are less than 1/3 that price and I can use them for other things too.Īs a cyclist, I'm desperate for a solution. I really want to get some expensive heated gloves that run a custom battery pack at 7.2 volts I'd get them if I could but they are over $100. I'm worried if I get the rechargeables, even if they last longer, they might not run the gloves as warm? What do you think? But they do work! At least enough to stave off my hands from freezing. Whereas I'm looking to get 3800mah rechargeables that will last longer and be reusable.īut will they heat the gloves as much? These particular gloves are super cheap and the heat barely works. If I go rechargeable it'll add up to just 3.6 volts.īut the alkaline (Duracell) are expensive over time and don't even last 2 hours. I have some heated gloves that use 3xAA batteries each. I wonder about the power output of rechargeable batteries vs alkalkine, as there is a slight difference in voltage.
