Sanyo NCR18650GA vs sony vtc5a?

[raggie33]

Which would you choose?

 

[SYZYGY]

obviously NCR18650GA (the best 18650 ). or VTC5A if you need more drain.

what kind of question is this? lol

 

[raggie33]

I mean for dependable

 

[SYZYGY]

dependable under what conditions? if you're using a quality 18650 while respecting its specs (incl current and temperature), are some really known to be more dependable than others?

just use NCR18650GA unless you need more current.

OK I'm talking power grid failure and I'm to my bug out place out in the wild

Unless you need more than 8A-10A, NCR18650GA has 35% more capacity than VTC5A and can cost half as much. And if you do, I'd like to know, for what?

 

[raggie33]

It is in my zebra

 

[SYZYGY]

NCR18650GA.

 

[chillinn]

I concur.

 

[raggie33]

Cool ty you both this was a hard choice I love sony since my first Walkman then my first play station

 

[Sjvalleydave]

I agree. I think the GA is a great battery, just doesn't work for me very often. I rebuild power tools, really need a CDR of, very, very minimum is 10A. Normally look for 15A minimum, much happier with 20+A. Still hard to beat the 25R

CDR = continuous discharge rating?

Do you have a solar charger for this? Lithium Ions don't do very well when they are discharged. Also, they don't like the cold too much regardless of charge.

Lithium Ions don't do very well when they are discharged.

They drop out of school? They're crabby and not good company? Help me out here, ampdude. What are you really saying?

 

[ampdude]

They tend to go bad pretty fast when they are below 30% charge. I think below 20% for too often is flirting with death. If they get that low or lower, charge them up right away. Doesn't have to be full charge, but put a decent charge back on them. And they get worse the colder the climate they're in. 45-80% charge is kind of the sweet spot for Li-ion longevity. But the chemistry just does not like cold. And neither do their circuit boards. In colder climates I would always prefer to keep them fully charged as possible. However, I live in the midwest tundra, so you might have different concerns. I keep a good stash of primaries around. And keep the Lithium-Ions I use warm and charged. And if I take them out on a trip, I understand their possible limitations. I don't know if you're familiar with lead acid car batteries and what they do compared to these, but they are a lot more robust. However.. they are normally considered 12 volt batteries right? Well they are actually 14.4 volt batteries. If you ever put a battery tester on a car battery and it actually reads 12 volts, it's basically done.

Why VTC5A and not VTC6?
VTC6 = 3120mAh and 30A CDR

While Sonys have a great specs and are spectacular when new, I've found that their cycle life is not the greatest. Their characteristics (DCAP and IR) deteriorate faster than say, Samsung or Panasonic/Sanyo cells, all else being equal. These days, I prefer more robust cells, and I'm fully ready to exchange some performance (when new) for extended cycle life.

PS: The max continuous discharge rate of the VTC6 without temperature cut off is 20 A.
