eneloop rechargable batteries

  • part 2 of my response

    ano mas magandang battery type na gagamitin sa LED flashlight? thank you

    depende sa situation kasi each has its pros and cons

    for example, i wanted a lantern that could stay idle for 1-2 years and it will be used sparingly, at lowest cost. So I chose a cdrking LED lantern with C-Zn D batteries. Since its unused for a long time and will be used sparingly, lifespan is important and high capacity is not needed. So that rules out almost all rechargeables since even eneloops have a self discharge rate, and li ions have a higher self discharge rate. Plus rechargeables cost more than primary batteries. Primary lithium (not li ion, these are not rechargeable) would have better lifespan but cost more so I live with C-Zn and just replace the batteries every couple of years or so depending sa expiration date.

    for EDC use, decent quality AA flashlights are usually cheaper since 18650 li-ion flashlights of the same quality use up more materials (bigger body) and have bigger LED emitters. If I need the extra lumens I go for li-ion, otherwise I use AA.

    In a situation where you cannot recharge then it may be cheaper to carry multiple alkaline AA's or buy from the local store than to carry multiple rechargeables or carry a large power source to recharge.

    li-ion is flammable. Aside from the higher lumens for the size, I like li ion since you can tell how much power it has left. Some li ion flashlights have indicators just like powerbanks. Thats a big annoyance for SLA batteries, you dont know if they are low batt or full.

    Speaking of SLA, price is low but its heavy and bulky.
  • Thank you for the helpful tip sir amalgam, I will be using an led flashlight for edc and it needs 4 AAA batteries,. Try ko muna mag alkaline,. Thank you
  • 4 AAA? Imo, that's not a good setup. Best for me are AA lights. You can use eneloops and primaries.

    Unfortunately, that's what my flashlight's battery size requirement. How does it become a bad setup? Can you enlighten me please? Thank you bro.

  • How does it become a bad setup?

    caveat, i'm no expert, go to the LED flashlight thread for confirmation

    usually primary AAA's and sometimes rechargeables cost nearly the same as AA's. Or even if slightly cheaper on a per mah basis talo sila. Of course with rechargeables its less of a problem than with primaries

    The only reason I was forced to have AAA's at home is my keychain light which has to be AAA due to the size I wanted and various remote controls for tv's, etc in the house. Otherwise I standardize to AA

    And having more than 2 batteries in a flashlight has some potential issues. It may simply be that they wanted more run time, but why not go with larger cells? Most likely its a cheaper model that uses multiple cells to achieve a higher voltage. Better quality flashlights have whats essentially a transformer that even with a single 1.2v nimh ups the voltage to what the LED requires. And they may be adaptive so that once the battery is getting drained and the voltage drops the transformer compensates. This increases battery drain but in return the brightness is constant until near the end. If there is no transformer then of course you get more dip in brightness as the batteries drain

    Also with some battery chemistries, multiple cells has a danger. If one has less charge than another then as it drains it may eat electricity from the stronger battery, causing various problems.

    Plus it just more difficult to change batteries

    on the other hand well if its what you already have and it works and you are happy with it then just use it, dont spend to buy a new 1 AA or 1 18650 flashlight. sayang pera

    just think about the advice if you need to buy a new one

    however, you mentioned its a cree brand? Thats a red flag, along with the police brand. The manufacturer has no name, has a poor reputation. So it just used the brand name of one of the suppliers of one of the parts instead of its own.

    just like a SUV years ago that was made in china but proudly displayed its mercedes engine

    Usually that means the brand name part - the LED emitter - works well and will last a long time, but the rest of the flashlight may break down sooner. From painful experience usually its either the switch or for metal bodied cylindrical flashlights, the electrical contact across the screw threads from the main body to either the end cap or the head

  • Wow! That was something I really need to put into consideration, I can't thank you enough for that substantial information. Anyway, sorry for going out of the topic (eneloop battery). But I really do appreciate your help! Oh well, it's my first time getting an EDC flashlight (and eventually obtaining other EDC stuff too), and now that i know the reason why nitecore,fenix, and other similar types of lights have only single battery requirement.

    Thanks brother!

  • Based on your experience guys ano mas ok yung plain eneloop or yung pro? Naiisip ko kasi di naman ma utilize yung napakadaming charge cycles. By the time maubos mo yun may bagong technology na. What do you think?
  • ^depends kung saan mo gagamitin. pero sabi mo nga, ok lang sayo plain eneloop.
  • hi po. Original po kaya yung mga tindang eneloops dito sa TPC? Ang mura kasi kumpara sa True Value. heheheh! gagamitin ko sana sa mga ilaw ko sa bike. :D
  • ricperez, orig yan.
