Absolutely terrified of my batteries.

[lost.n.disturbed88]

Alright, so I'd like to keep from blowing my face off... And haven't done much as far as battery safety (I'd let my one battery charge overnight). But I got a battery from my local b&m store yesterday. It's bigger than the battery that came with my zmax, although it still fits and secures. Quite broke right now (first of the month... yay bills) so I'm not in a position to buy better stuff right now. But from the below list, what should be my biggest concerns and how can I keep my current relationship with my face?

Ok, here's my stuffs.

Li-ion charger (came with zmax)
model nk-803
input ac100-240v 50/60Hz
output 4.2v=1000 mah

A blue (no visible brand) (came with zmax) 18650 2200mah 3.6v (with a button on top)

A trustfire 18650 3.7v li-ion 3000mah (also has a button on top)(bought at local b&m)

A sigeli z Max (... came with self )

Thank you.

Oh. And the trustfire Battery never actually made my charger light turn green.... I placed it on my table and watched it for 6 hours. It stayed red. However, my zmax read the battery at 4.0v and quickly went to 3.9v

I'd recommend a quality battery charger. I have a Pila and it's just great. Also a battery case for toting extras around.

Good prices on batteries and chargers. I feel like you need to replace both. I don't have that device, so I won't tell you what batteries to use, but plenty of others will.

A better question might be; do you think these items will safely hold up for about a month before I can afford good stuff

I'm pretty certain they will. Don't let it worry you.

I'd worry about a battery that went red and never turned green. If your charger actually does have a 1000mah charge rate it should take roughly 2 hours to charge a battery.

I'm happy with my Nitecore I4 and very satisfied with the Trustfire TR-001 that served me well for years before that. I've never had a battery not turn the LED green in a reasonable amount of time. Your Trustfire should have hit 4.2 and turned the light green.

It's a common saying around here, "Never buy a battery with trust or fire in its name". That's probably over the top, but there are better brands to love. AW, Panasonic, and Sanyo come to mind and there are many variants and re-labels on the market.

What about my pv? Will I get a warning before a boom?

Sounds like the same charger and blue battery I got with my Vamo V2, except my battery is a flat top. Been working fine for about 2 months now.

If the cartoons I watched as a kid are true, usually a loud ticking sound. (Just kidding).

However:

Lithium battery venting

Bear in mind that this is a worst-case scenario, a direct positive to negative short circuit.

Now, take a deep breath, and turn your Zmax upside-down. See that hole (or those holes) in the bottom cap? Those are there to allow battery gases to escape should the battery vent, instead of allowing pressure to build up inside the tube until it ruptures.
