![]() And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. but i don't mind that when i know i'm going to always have a steady voltage powering the lightsaber and the blade won't start to behave oddly because the batteries need to be replaced (others may feel that to be a 'feature', which is cool).ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. and they won't last as long as alkaline or lithium iron disulfide batteries, so you'll be removing batteries more often. if left alone, fully charged, after a few weeks they'll need to be charged again. the drawback of these batteries is they will self-discharge much more quickly than alkaline batteries. when the battery needs recharging your blade will simply stop working. your blade won't start changing colors as the battery drains, like alkaline or lithium (iron disulfide) batteries will. the end result is from fully charged to fully drained, these batteries will ALWAYS produce 1.5 volts. the internal lithium ion battery puts out about 3.7 volts and circuitry inside the battery regulates that down to 1.5 volts. they're a different type of lithium battery (lithium ion, whereas the disposable lithium batteries are lithium iron disulfide). if you don't like having to change batteries often and are willing to pay extra for that then these are the way to go.Ī third option i've been using for a while now, and i prefer, are rechargeable lithium batteries such as these. Lithium batteries will last longer, but are more expensive. they perform nearly identically to name brand and will cost significantly less. lithium batteries should have a lower chance of leakage than alkaline batteries.įrom a cost perspective, cheap alkaline batteries are the way to go. the best way to prevent them from leaking is to remove them from any device that you're not going to use for a while (a few weeks or more). The bigger advantage for hobbyists IMO is that you can substitute (AS LONG AS YOU DON'T TRY TO CHARGE IT) them with AA's in a pinch, and AAs have massively longer shelf-life so for rarely used gadget they are superior.Īll batteries have the potential to leak. But then your phone can just decide to do same so I don't buy it as a good reason. ![]() ![]() You can get decent lithium at few times the capacity and more convenient voltage for like $2-3īut yeah, no explosion. > AAA-NiMH cells are $1 each ( ) and available from a wide variety of trusted manufacturers (Eneloop, Energizer, Amazon Basics and more). And you often can get charging circuit for free if you pick one of the more specialized ICs Which is still not "good" for Ni-MH, just not dangrerous. Only difference is that you need voltage limit, instead like for Ni-MH where you just can let battery burn it for heat. Current source with anywhere between 1/10C to 1C and max voltage of 4.2V (4.1 if you want some more cycles out of it or safety limit for parts tolerance will do just fine. Sure if your budget is limited to "a resistor", but if you don't care about quick charging you can "just" do the same thing. ![]() Li-ion has complicated charging circuitry NiMH has extremely simple charging circuitry. ![]()
