Replacement battery for Bosch drill

[kjacko]

Hi all,
i have a Bosch GSR 14.4-2 professional series drill/driver.
Had it about 3 years, came with 2 x 1.5mAh ni-cad batteries. They've lost quite a lot of their umph now but seeing as its a really good drill still im wondering whether i can buy a new battery for it that's maybe more powerful, ie 2.0mAh. Or even a li-ion drill as some drills will take both types.
I'm awaiting replies from emails i've sent to a few etailers, but wondered what you guys think?

Cheers

very very few manufacturers keep the fitting the same when they change the batteries
probably cheaper to buy another tool with 2 batteries
screwfix and its london amounst other sell spare batteries or you could try a recell company

powertools pro a good reliable company

Thanks big-all,
i got a reply from one place who have a ni-mh 2.0mAh battery which will fit my drill. I just need to check if my existing charger will work for the ni-mh battery, if so, then that sounds like a decent upgrade over ni-cad for an extra £15.

A new li-ion battery would cost me well over £100, so a <£50 upgrade option seems the better option sas i'm not a tradesman who uses it daily.

Am i right in assuming that the high the mAh rating the longer the battery will last between charges?
It doesn't make it more powerful than a lower mAh battery does it? Unless you move from ni-cad to ni-mh or li-ion?

Like having bigger fuel tank in your car, doesn't make the car more powerful, just longer between refuels?

volts = the car engine amps = the fuel tank

if your talking about re-cell batteries with li-ions then i personally dont like the idea because li-ions need different charging routine

if its a different battery it wont fit the charger or tool

yes you can upgrade to larger ah batteries as they do batteries above 2 ah so the charger will cope

So, if i were to buy a new 1.5mAh ni-mh battery (as long it my charger will work with it) it should be quite an improvment over my 3 year old 1.5mAh nicad ones, because;
1. its new
2. from what i've read will be more powerful as ni-mh is better technology and not suffer so badly from the memory effect?

if in doubt read the charger or google the charger then it will tell you in the specs
