Hi guys. New guy here, I have little knowledge when it comes to repairing battery packs for cordless drills.
What concerns me is the AMPS in all this "story".
I have an older(from 2007) 14,4v cordless drill that I got as a gift from grandad.
Battery is almost dead, barely holds up for 1 minute.
But the drill is working fine and I like it, so I would like to repair the battery pack.
I opened the pack and inside I found four "Sanyo l UR18650SA 025A" cells.
I can't find exact specs, some pages say its discharge current is 10A, others say its 18A but cell has mentions of 025A on it.
I was looking trough the store, and I found these **broken link removed**
They have Max Continuous Discharging Current without temperature cut: 20A
But also Max Continuous Discharging Current: 30A (with temperature cutoff circuitry at 80 degrees)
I bolded this for reason I don't understand it, what does this mean ?
Now the main thing.
Lets say this, these Sanyo cells have discharge current of 10A, but Sony VCT5 cell have discharge current of 20A.
If I replace my old cells with these Sony VCT5 cells that have higher discharge current, will that cause any problems ?
Can the drill, or the motor or the board inside the battery pack, can anything burn out ?
