Crap Tenergy Nimh Cells from Amazon

Well kinda shows you how u save money by buying 1/2 price batteries what you get. Anyways, mine kept buzzing in my flashlight the TK70. After a few charges, I can tell it’s not calibrated right etc…
Anyways long story short they cycle like very fast, under a second discharge and 15 mintues charging. I think the batteries hold about 500-600 mah from the quoted 10,000 mah. Just gonna guess wildly that they hold turbo for about 5-10 mintues until they will just only do bursts of turbo. I’m gonna buy some powerex to see if this solves it. Anyways just wondering if you guys have the same problem. Also how long do you guys charge yours? or should I invest in a dedicated D nimh charger? I already have an accucell 6 & was hoping that it can charge them.

I bought mine from “Battery Superstore”. Other brands seem to be selling 2 for 30+ dollars. Wondering if these are flooded or fire damaged cells from other threads I’ve been reading.

If you have an Accucel 6 just charge one and then do a discharge test to see their capacity.

The tenergy blues or the premiums (white)?

The tenergy blues buzz in my TK70 as well. Guess its time for some runtime tests.

Man fasttech needs to get in some hobby chargers. I know as soon as I buy one elsewhere they will have them

They are whites. link here.
