Rechargeable C Batteries - Tenergy Premium Quality

Amazon Customer: The charger that came with the batteries claimed to have completely charged them but they didn't hold their charge & by the time I needed them, the batteries were dead & I needed to charge them again

Fernando V. Padilla: I saw them and they looked nice, but they discharge too soon, are not high capacity, and did not out perform a cheap alkalyne from a 99 cent store

burnem79: I used a set of 10 batteries to rebuild a battery pack for a HID flashlight after the original cells died. I ended up 3D printing a battery holder and bought battery terminals/springs to make these replaceable vs the solder tabs on battery packs. So far so good with these, they hold a charge for a long time. The output is great too for this high drain light. I will buy these again if I need C cells for any other device I have.

J. Bruha: I always had good luck with Tenergy batteries, and see no reason to think otherwise with these. These are the Tenergy 'premium' line, and I haven't had them long enough to know how many charges they will last, but they do seem to last a bit longer per charge than the Tenergy standard line.
I am moving to putting rechargeable batteries everywhere it is practical, for two reasons. First, keeps acid and chemicals out of landfills, and second, I have yet to have a rechargeable battery leak and damage the device I put them in. Yes, if run down and ignored for a long time, they are stone cold dead, but at least they are not sitting in a blob of acid and corrosion.

Nils Valentin: [Capacity:]
Tenergy seems to have world wide the highest rated capacities for rechargeable NI-MH batteries.
Looks like Tenergy has almost maxed out of whats technically possible.
No other maker has these capacity range, hats off !!

Even the best Japanese makers have max roughly only 60% capacity (3000 mah), again respect for this !!
It's awesome how much capacity this rechargeable batteries have.

[Weight:]
Lets face it, batteries are heavy. Capacity limits and weight are probably their worst obstacles.
Fortunately the extended capacity plays as advantage as you might come by with one battery pack where you used
two or more in the past. This comes in VERY handy when either every gram counts or stamina is everything.

[Charging:]
We all know that increased capacity not only gives you better mileage but also requires fewer (but long) charging cycles.
Generally speaking high capacity is a good thing but long charging times might be a turn off when you are in hurry.

In addition quick charging or charging to often (to early) might decrease life cycle of the battery (read: damage it). So it
makes sense that you also invest in an...
