When a person gets in his late 70's he believes he knows most things. Rest assured that is not true and I have allowed myself to learn anything I can.Here is what I have learned lately;
Makita in their wisdom created a battery protection system unlike any other on the market. There Li-Ion batteries and chargers operate from four parameters of information. All parameters must be met before the battery can be charged. If one parameter fails the circuit board in the battery gives the charger three attempts to function. If it fails to comply the chip in the battery shuts the charging circuit down permanently. This wisdom was probably implemented in a safety protocol all corporations use against liability these days. They think.
I thought this was some conspiracy theory by other entities, but in my opinion it is not.
Bottom line,
I have two perfectly good batteries sitting here that I can charge with all safety features intact, but they can't be charged with a Makita charger.
I use a universal smart charger that performs all safety parameters as the Makita but is not influenced by the Makita chip. My charger has the ability to charge multiple batteries at a time of all brands but cannot perform the function of product brand specifics.
Once I run the gambit of tests and conclude the battery is functional I still do not know if the specific brand charger will charge or not without having that charger. This implies that I have to have dozens of chargers in house to know if I am finished or not.
I think technology has come close to perfecting the perfect OSHA approved device. If the charger does not charge no one can be hurt. Perfect world, unless you need to use power tools.
