Makita tool battery charger options

YOU ASKED,

What would you recomend for an optional battery charger for a Makita LXT with a bad chip?

MY ANSWER.

I believe that Makita has probably taken care of the discussed problems with there new production but we will never know. Also the fact that there is a device to reset the chip is possibly a figment of someones imagination. I hope it is true but who knows.
 
As a re builder I am very cautious not to mislead my customers about the possibility to rebuild their batteries without a disclaimer. It is possible to change out cells but that does not constitute a rebuild if it can not be charged.
 
The type of charger you need is obviously one designed for Li-Ion batteries and offers at least two parameters of protection. I prefer a third parameter but it is not mandatory.
 
1. Protection from overcharge.
 
2. Protection from undercharge.
 
3. Protection from heat buildup. (Optional) 


No chargers, even the OEM makita will balance cells within the pack. They only detect unbalance. If a cell is bad the charger shuts down. If that happens the only recourse is to find that cell and replace it with another that matches the rest of the pack.
 
The charger I will recomend has the ability to balance individual cells for optimum performance but will not make a bad cell work again.
 
With that said, I will list the charger I like, to replace your OEM unit.
 
This charger is on sale right now and goes off sale on 9/10/11.
 
 
Remember, I am a battery rebuilder and share information for the possibility of future interaction in my small business.
