Batteries before and after rebuilding, recycling.

This illustrates what the typical battery looks like when it is sent to me.

I call this a swimmer. Tools are let set in the weather or in tool trays that collects water until the pack looks like this.

There are vents on the bottom of the case that provides ventilation for cooling. The vent tube only go into the battery 3/8" and when the water get higher than that the pack has to tread water.

No matter that you notice,  the water has no way to get out. The only way to dry it out is to dissasemble it.




The pack on the bottom is ready to install in the case for a new lease on life.

Rest assurd, if it sets in more than 3/8" of water it will look like the one on top. They are not good swimmers.

Differences in Eco Friendly battery rebuilds and complete battery rebuild.

Eco Friendly Rebuild

The used batteries that I have offered as Eco Friendly have been disassembled, and cells tested for usability. I take a comparable set of used cells that produce a minimum of 1300mah and install that pack in my cases to complete the repair. They are tested on the computer.

Complete Rebuild 
The batteries that are being sold as Seller Refurbished are those that have been disassembled, all cells removed, a new pack is built and installed utilizing new cells of 2200mah in a customer provided case, tested, and sent back to the customer.

Either battery Eco Friendly or Complete Rebuild are repaired in a battery lab with state of the art equipment by a qualified technician.

In an Eco Friendly world the process of rebuilding batteries alone supports the overall interest to clean up and control hazardous waste in our enviroment.

The big advantage to an Eco Friendly rebuild is the using of all cells that are deemed usable by the test equipment and the overall cost to the consumer. Each rebuild has a warranty and complete support from our operation.

This is a Win Win approach to hazardous waste reduction.

Makita power tool battery circuit board problems

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.

Eco Friendly power tool battery rebuild, recycling

Being Eco Friendly is an important responsibility.

These batteries like others listed in my store are those that have been disposed of either in recycling or in landfills. Most of these batteries were unusable, mostly by the shorting out of a cell or two.

I completely disassemble each unit and test all cells for   usability. 
I add cells from other teardowns of like compatibility until I get a pack that performs.  This minimizes the impact to the enviroment as well as supplying my customers to low cost replacements.

Almost 90% of recycled power tool batteries and similar types of batteries around the job or house are generally put into landfills. There is not enough volume of recyclable materials to promote recovery operations. You might have good intentions and put your batteries in a recycle container but sadly they are not.

Purchasing this battery will not change the worlds problems with hazardous waste, but it all helps. 

I have invested a lot of time in this program and so far it has proven successful. I feel better and the customer gets a good product with a warranty.

The process includes at least the following:

1- Completely dismantle used batteries, Test all cells and replace those that fail. Test the pack on a computer aided breakdown testing unit and confirm the rebuilds usability.

2.  The battery is ready to go back to work,

3. Full replacement 30 day warranty.

4. See my eBay store for details.

Power tool battery rebuild performance information for professional and craftsman.

Most batteries have a limited cellular construction with an average of 1300mah output. This is normally enough for small projects in the vicinity of a charging unit and a ample supply of backup batteries for continuous operation. As a contractor it seemed that the further we were away from support equipment or the higher we worked off the ground the greater the risk of failing to complete the job with the available batteries within arms reach. After climbing down the scaffold or walking across the field a number of times it was obvious the amount of batteries we packed increased as our stamina declined. Most power tools utilize batteries with Nickle Cadmium chemistry. These have worked very well but are restricted by output in a sub c format. There are new higher output cells to replace the lower output OEM units. A discouraging fact with sub c cells is the inherent loss of power as a cell sets. A ni-cd cell will lose 1% of its available power every 24 hours. Or 30% each month. This requires a program of maintenance to keep batteries at their maximum performance level. If not, just expect another trip or two down the ladder. We can rebuild with Nickle Metal Hydride cells. This chemistry allows us a higher output than Nickle Cadmium. In some cases the output is double. Batteries rebuilt with either Ni-Cd or Ni-MH will offer approximately 500 cycles of charge/discharge before problems. The difference is the amount of usability between cycles. NI-MH batteries of 3500mah compared to NI-Cd 1300mah is obvious. Do the math. This increase in performance is significant to the usability of cordless power tools. All batteries we rebuild will be tested on a computer aided battery analyzer prior to shipment. It takes up to four charge/recharge cycles to balance a pack to its maximum capabilities. This record will become a permanent baseline and record of every battery we rebuild. If there is a suspected problem with a battery pack after delivery we can compare tests with the records upon its return to us.   Next blog will explain the advantages of "Eco Friendly Rebuilds". OUR BATTERIES ARE REBUILT FOR THE HARD CORE PROFESSIONAL OR CRAFTSMAN WHO NEEDS PERFORMANCE FROM THEIR POWER TOOLS.
