How can I identify the battery I own?
Most every battery has a tag located somewhere on the outside, identifying the battery chemistry (Ni-Cd, Ni-MH or Li-Ion) and voltage. If the tag is missing, sometimes you can locate the information on the charger that came with the tool and battery.
How do I know if my battery is a type you can recondition or rebuild ?

On what kind of battery can I use my existing charger?
If you own a Ni-MH battery charger, you can use it to charge your Ni-Cd batteries. You cannot use your Ni-Cd charger on a Ni-MH battery. Li-Ion batteries can only be charged on Li-ion chargers and Li-ion chargers can only be used on Li-ion batteries..
What kind of equipment do you use to recondition or rebuild my batteries?
We use a Sunstone pulse spot welder and a Cadex battery analyzer. Sunstone is a US based company. Cadex is a Canadian company. The founder of Cadex wrote a book about batteries titled Batteries in a portable world.
Why would I rebuild an old battery instead of buying a new one?
Many times it is cheaper to rebuild a battery rather that buy a new one, but that's not the only reason why you should consider rebuilding your battery. It is very possible that we will use more powerful cells to rebuild your battery pack than originally were used by the manufacturer. That means your battery will be "better than new".
What is the proper way to recharge my battery?
Always follow manufacturer's recommendations, however the general rule of thumb for nickel based batteries are as follows; a fast charge is better than a trickle charge (trickle charges are for lead-acid batteries), remove the batteries from the charger as soon as they are charged, and don't try to charge them when they are very cold or very hot (room temperature is best, between 50 and 80 degrees F).
