Carbide die grinder bits and any roloc stuff up to 2", not got the power to do over 2"

I love mine.

I cant recommend non genuine no and the cost of Milwaukee batteries isnt really that bad unless your wanting the higher 8 or 12 amps ones then it gets expensive, but so are the tools that require the higher amp.
Genuine batteries in my experience last forever unless you drop them awkwardly.

Question,
I have 1 x 9 amp, and 6 x 5 amp,
Used in Angle grinder, impact wrenches, zip saw, and blower, recently notice, they soon run out of charge, put in charger, and immediately go to charged lights,
I’ve a feeling, possibly the angle grinder, is damaging the batteries,
Any ideas ??

how old the batteries

 

[grainboy]

Yes they have done a lot of work, but 2 are lots younger,

try a different charger, if you dont have one then you certainly want to buy the rapid charger anyway.

grinder wont damage the batteries but it will flatten them quicker than most tools.

i have too very old 4 amp batteries and they work fine, all mine get used on the grinder 4amp, 5amp and the 9amp. i use what ever needs making flat first so it can be fully recharged, not a fan of leaving batteries flat or part charged any longer than necessary, the only exception to this is my remote control car batteries that are lipo's which you always want to put in to storage charge after use as leaving flat will damage them just as much as leaving them fully charged, also the fire risk of leaving fully charged is much greater.

I have 3 chargers,
batteries are used till dead, then charged,
My 9 amp, will not charge now,

Leaving Lithium Ion batteries flat for more than a few days risks killing them. They do not tolerate being discharged much passed their tool cut-off point. Better to store them partly or fully charged than discharged. All my various batteries are recharged as soon as they cut off due to low charge and they last years. Ideally they would be stored with 60 to 70% charge but it's a clever person that can manage that consistently.

Jump start the 9amp for a couple of seconds off a fully charged battery.
Then charge it.

It will raise the cell voltage to were the charger can recognise it.

If that dont work then its toast.

How do you jump start one ?
sorry for my ignorance,

How do you jump start one ?
sorry for my ignorance,

Link the two batteries together with bits of wire + to + & - to -.

Ive done it but i believe it is a bomb
