Thank you for suggestions. I checked all D cell reviews here. And it seems Soshine is a good choice as per reviews.
where to buy soshine or tenergy centura, for India shipping. Above mentioned post (Massive post on where to get lithium-ion batteries everywhere in the world!) does not provide any Asia related site.
https://ru.nkon.nl/ or somewhere else. Shipping and covid19 restriction are important.
Need 1 more suggestion for 2032 batteries. Panasonic or Duracell?

For 18650, as I posted earlier, after watching YouTube comparison I selected LG MJ1 but there are more batteries available compared in this old video. So guidance needed.
I checked battery index (https://lygte-info.dk/info/batteryIndex.html), for max 3A and 3.7v, LG, Samsung are good and available locally as I mentioned sites above post. but no Keeppower locally available.
primary applications will be 3V-5V 3A diy arc generator, arc plasma gas lighter circuit, replacing very old Dell Latitude D530 laptop battery 6 li-ion cell, 11.1V, 56WH (year 2007) (Type M9014)
secondary applications diy power bank and some other stuffs.
Batteries with ridiculous ratings - https://lygte-info.dk/info/BatteriesRidiculousRatings%20UK.html
I think I will try 1st high capacity batteries, from below whichever costs lower.
Samsung INR18650-35E 3500mAh (Pink),
Sanyo/Panasonic NCR18650GA 3500mAh (Red),
LG 18650 MJ1 3500mAh (Green)
If they discharge fast then I will try high current + high capacity batteries mentioned there, from below whichever costs lower.
Samsung INR18650-30Q 3000mAh (Pink),
LG 18650 HG2 3000mAh (Brown),
Sony US18650VTC6 3000mAh (Green)
Any suggestions for this?
