||Batteries 101 - Interview with Journeyman
When I got my first AEG (a Tokyo
Marui MP5SD5), it was meant to use a large 8.4v battery but the one I had was a 7.2v
I needed to know if I had to buy another
battery. So, I decided to interview Journeyman, a seasoned player, on this topic
since I know there's a lot of newbies out there who may
have this same question.
I have a Tamiya 7.2v 1700mah battery
that has been charged for a couple of weeks now... I only
shot a couple of hundred rounds with it. When I tested the
gun at the field I used someone else's battery. It was a
Sanyo 8.4v 1800mah Platinum, and simply left mine at home...
Am I supposed to discharge the battery before I put the
The guys told me to buy an 8.4v battery
since my gun would "lack performance" if I used
the 7.2v. I'm on a tight budget and I need to buy a charger
too... so, should I really get the 8.4v battery AND a
battery discharger??? And what difference does it make which
one I use?
All stock AEG motors need 8.4v battery power to work at
their best performance. There are batteries with higher
voltage like 9.6v or even 12v that are used for upgraded
guns with more powerful motors, or just to speed up more
the regular motors. If you use the "more punch than
8.4v" batteries with a non-upgraded gun you'll damage
- Voltage related to the battery's power and a higher
voltage results in higher rate of fire.
- mAh is simply the battery's
Most batteries are of the Ni Cd kind and have to be fully
discharged, through use or using a discharger, before they
are recharged again. This results in better performance
of the battery, they last longer and reduces any possibility
of the so called "memory effect" that reduces
it's capacity. I'd recommend using a discharger (about 10€).
I am also of the opinion of buying the right battery for
your gun. I have the official Tokyo Marui 8.4v MiniSD which
is specifically for my gun (a Tokyo Marui G36c). It's a
small capacity battery (600mAh) but it gives me no worries.
I bought my charger from an electric equipment shop for
about 25.00 € if I remember correctly.

That information really helps out. I
had thought all along that voltage would only affect the rate
of fire and not actually increment the speed of the BBs, but
I needed to confirm with an expert.
So, I really, REALLY don't need to
by an 8.4 battery unless I want to shoot faster... AND I
need to get a discharger to prolong the battery's life and
ensure it works right, for a longer time.
You also mentioned that a small 600mah
battery didn't give you any trouble... which brings me to
my next question...
How many shots can you get off
your 600mah battery before it starts running out? Furthermore,
from what I understood, a 7.2v 1700mah battery will shoot
as many rounds as an 8.4v 1700mah battery since what determines
the length of battery is the mah number.... so, after you
answer how many shots you get off the 600mah, then I can
just multiply that by 3 to know how many shots I'd get off
With my 8.4v 600mAh battery which powers up the EG1000 motor
of my Tokyo Marui G36c, I can shoot approximately 10 standard mags
(50 shots each), so this adds up to about 500 bbs. I don't
use hi cap magazines so I try to pick my shots and that's
why it doesn't bother me that much that the bb count is
<<< After paying closer attention,
I noted that my G&P 600mah battery has shot over
1000 rounds without running out using an ICS M4A1 >>>
Mind that temperature affects the total amount of shots
your battery can provide for a given capacity so, for example,
on a hot day I might be able to shoot more than 500bbs with
