Hello:

I've just purchased a replacement battery for my 7.2 volt Makita cordless drill 6070D. The battery is the type that needs to soldered to the terminals, as opposed to the click/snap in variety. I asked the service department to charge the battery prior to sending it to me to make sure it would take and hold a charge before sending it to me. My qustion is this. On the supplied sales slip the service department wrote a note that read: "Note the battery is fully charged, make sure to discharge battery prior to soldering in into your cordless tool".
Does any one know why I need to do this and is it not possible to just solder the battery in the way I received it?

Thanks to all those who reply. Sincerely,

Jack

 

Jack,

One reason could be that if the terminals were accidently shorted, the battery could explode.

Just out of curiosity, what does a replacement battery cost?

 

I live in Canada and I paid about $40.00 which is about what I paid for the drill 15 years prior. The safety factor is the only thing I could think of as well. I also purchased a new charger, as I found mine to be faulty. Price for that was another $15.00. I should just have bought a new drill for all the money I've laid out so far. Thanks for your input.

Jack
