One friend of me is in to paint ball. And his “gun” is using AAA batteries. Several stores around the world sells “Extreme power Alkaline” 1.5V batteries, but they are not rechargeable.
I’m thinking he is better off with Eneloop Pro batteries in this case. He will save money since he can recharge them, but, is the “paintball” battery more powerfull then Eneloop Pro? For in “battle” he must have max power at all time.
What do you think?
Not a chance the alkalines are better than Eneloops. Check out this site:

You can see that AAA alkalines are only good when the current is 0.2 amps or less. Ideally, stick to 0.1 amps. Look at the awful voltage sag and pitiful capacity when used above 0.2 amps.
Whereas AAA Eneloops give decent performance up to almost 3 amps.
There’s just no way that alkalines, any alkaline, can deliver the kind of performance that Eneloops can.
The only time that alkalines may be necessary is when you are using them in a very low drain device, where high voltage (1.5 volts) is required. In that case, Eneloops (or other NiMH cells), will only give about 1.3 volts. Very few devices actually require 1.5 volt cells, and none of them are moderate or high drain (because alkalines give lower voltage at higher drain).
tnx, going to order some Eneloops to my friend.
They’re just alkalines with fancy packaging/marketing, no way they can beat an eneloop nimh.
beat me to it.
I was at the shops today and Fuji sells these extreme alkalines they claim they are better then NiHM batteries I think they are high mah capacity alkalines…
Sounds like Fuji are talking poop. Alkalines have dreadful performance, and they will leak. We had a bag of used ones at work, almost all had leaked. Even cheap Chinese LSD NiMH are far better than alkaleaks, and for many purposes as good as Eneloops and rebranded versions thereof.
For any application requiring moderate or high drain, NiMH batteries are always better than alkalines. The capacity of alkalines drops a huge amount if they are used in high drain devices, as well they suffer from big sags in voltage. NiMH suffer very little from these issues.
The only time an alkaline wins is if you use it in a very low drain device, such as a clock or remote control. The capacity of the alkaline can be significantly more than NiMH rechargeables in such low-drain applications, plus their voltage level will be higher than NiMH for about two-thirds of the discharge curve (until the alkaline only has about 33% capacity left).
An alkaline has one other advantage over common NiMH cells: they self-discharge slowly (have a long shelf life). However, NiMH Eneloops solve that issue, by maintaining 70% of their charge after 10 years sitting on a shelf. So, Eneloops are an almost perfect replacement for alkalines. (And Eneloops won’t leak caustic goo all over your device like alkalines will.)
tnx for all info. Somebody have found away to “milk” money out of paintball players, of course only selling onetime use batteries, instead of rechargeable batteries = less money.
He will save money after he has used the 8 batteries 4 times (or any combination alike).
Also NiMH means less waste in landfills so you won’t be killing bunny rabbits and destroying the planet.
if higher voltage helps the gun you could try energizer lithiums too.
Some devices do not work properly with the lower voltage of nimh batteries, but for all the other devices it is better to use low selfdischarge nimh batteries.
And for higher currents nimh is Always a better choice than alkaline.
Lithium AA and AAA batteries can sometimes be the right choice (better at low temperatures, very long shelflife, and the voltage stays higher during discharging), but they are Always more expensive per Wh or Ah than nimh and alkaline.
