A big problem that many MFLB users experience is a gradual decline in the power that the MFLB seems to be putting out. Some may think its due to some sort of tolerance problem, and in some cases it can be, but for the most part its due to the stock batteries being worn out. They wear out very quickly and continue to degrade with every charge. You will notice the orange light not lighting up as bright even after a fresh charge.
The fact of the matter is, the stock batteries do not bring the MFLB to its potential.
MFLB Mod #3 - How To Upgrade The MFLB Batteries
I. THE BATTERIES:
The MFLB can take any rechargeable batteries that are over a 2000mAh rating, and the higher the mAh, the hotter the box will run. Any replacement batteries will have to be peeled before they can be used with the MFLB.
For my choice, I chose the Powerex 2700mAh 4-Battery set from Amazon. These batteries are a very popular choice for an upgrade, because they are a very high mAh and are very cheap. Heres a link:

Mine arrived in only a few days in a nice plastic case.
Something I noticed about these batteries right off the bat is that they seem heavier then the stock batteries. I did not test to see if this was true, but they definitely feel denser.
The first thing you will need to do after receiving your batteries is peel the wrappers off of them. This allows them to fit into the MFLB and make contact.
I usually start with the tiny exposed flap at either end.
Just begin peeling away at the wrapper until it is completely off and has left a nice big patch of glue for us to deal with.
Now its time for the hard part, cleaning them.
I start by rubbing them against a thick piece of paper to get the glue to ball up and fall off. After doing this for a while, I usually get a towel and rub them to try to get any more glue off.
This is a VERY annoying and slow process, but it must be done.
You will notice there will be one big line of glue that just wont come off easily after all the other glue comes off, this is normal. I used a piece of hard plastic to scrape at it and then I kept polishing it until it came off (after what seemed like hours).
Now do this 3 more times
At this point, you will have 4 new batteries that are as shiny as the ones that came with the MFLB.
Now for the comparison.
So heres a comparison of the stock batteries versus the new 2700mAh batteries in regards to the light brightness:
Both were at full charge at the time of this photo.
Its clear that the 2700mAh's put out ALOT more energy and in turn, a lot more vapor and a lot more heat. They old a charge well and seem to last a lot longer then the stock batteries did for me.
I highly suggest upgrading from the stock batteries especially if you have had a MFLB for a while.
