Cordless Power Tool batteries - Rebuilding for improved performance

CORDLESS POWER TOOL APPLICATIONS - ALL BRANDS AND MODELS

Cordless Tool Batteries - we make them work like they should.

We do not offer new tool battery packs.
Our quotes are for rebuilding your old battery pack. (It must be sent to us.)
If you are considering the purchase of new battery packs from the original manufacturer.. remember this: If your tool is 5 years old... it is likely that the existing replacement packs are also 5 years old. They stopped making the battery packs... when they released the new model, and the gadgets that go with it.. If you do not care about the gadgets that draw most customers into the "buy a new one" trap - then you are our intended customer. Our purpose is to provide improved performance... for use by those who require only the best. It is not our intention to compete with low cost replacement batteries. Remember that the poor quality battery problem will continue... it is sold to you along with the new gadgets and doo-dads. If you do not require more than a casual use of your cordless tools, then you should probably search for the lowest price.
When rebuilding your old battery - we only use factory fresh cells, that exceed the original specifications. There have been considerable increases in the capacity of all rechargeable cells, and they continue to improve every day. Your power tool has never had it so good. Battery packs for cordless tools may be viewed as three categories. They are typically graded by voltage and capacity. The voltage indicates how many 1.2 Volt cells are used. (10 cells = 12 V). The mAh or AH refers to how much energy can be stored. The higher the number, the better the ability to provide continued use without recharging. The physical size of the cells, and if they are NiCd or NiMh ... determine what can be used as a replacement. Battery capacity measurements are based upon finished product testing with top quality cells. Often times cells may be marked with capacity ratings that are misleading - some perform better - others less - we test to make sure.
Standard capacity packs: They are usually sold in pairs, in kits with do-everything attachments. They were made at minimum cost, with small size cells, that provide little operating time. These batteries often spend more time in the charger, than they do in the tools.   The batteries are usually only 1.0 AH cells, we rebuild them with the highest available capacity. (depending of the model the upgrade can be 1.3 AH or higher. The result is usually a 25 to 35% increase in run time.

Extra, XR or Maxi etc. battery packs. These are large capacity NiCd packs, they are usually 1500 to 1700. We automatically replace these with 2.1 to 2.4 AH cells for a 40% increase.

NIMH -Maximum capacity packs: NiMh batteries are usually available in two battery sizes. Small packs were 1.5 AH and large battery packs were 2.2 AH We rebuild the small case with 2.1 AH and the larger packs are improved to 3.3 AH. Either rebuild usually adds 50% more run time.
   Some batteries can be upgraded from NiCd to NiMh cells - The question is can your charger be used with NiMh? Unless the original charger is identified for use with NiMh, it is probably not adaptable to NiMh. The charger may not provide an adequate charge rate to fill the larger capacity NiMh cells. This condition is usually never noticed, since even if not completely filled, the battery will provide much more run time that the original NiCds.

CAUTION: Do not repeatedly recharge the battery without discharging. This will over fill the battery, and result in excessive heating. If it feels very warm it is being over charged, and must be removed from the charger. Failure to do so will result in damage to the cells, and could result in bursting of cells if they are extremely hot. Approach the charge process with caution, monitor the charger and battery to notice any problems.       If you are not satisfied that the performance is adequate, you should purchase a NiMh charger. There are many such chargers available on the internet. (eBay).

You may think there is no way to open your battery case ... but we have the tools and techniques necessary to open and reseal them.    Many contractors, manufacturers, service companies, and maintenance departments, are using our rebuilds - and they say they "will never go back" ... Let us rebuild your old pack with our extra capacity cells.   Stop tossing your valuable tools away - stronger batteries improve the performance to better than new. We guarantee you will like it. Our workmanship, and battery performance, are warranted for 30 days.

Which battery rebuild choice do I need? Let us worry about it: we guarantee that you will like the renewed performance.   There are many variations within styles and brand names. The battery will be returned to you with the highest capacity cells that can be used to rebuild it. Our prices for rebuilding tool batteries, is based upon the voltage of the battery pack, and the choice of NiCd or NiMh. This is because there are so many variations used in the field that it would take volumes to list them all. The capacity values listed represent the minimum. All cells used are greater than the listed 2100mAh. Actually, higher capacity cells are used in many packs, up to 2600, and larger cells are in the future. The values change faster than the web page revisions can be made.
