Hello,

My cordless screwdriver seems to be on its way out. Its a Bosch model
hat I have had a for a few years. What is the life expectancy of the
batteries in these? I presume they are not replaceable?

I think the battery is worn out because it will not hold a charge.

Is it time to upgrade to a new one? Do you recommend a dedicated
screwdriver or should I use the opportunity to get a cordless drill? I
would think a drill might be a bit too bulky for screws.

I suppose you might recommend an impact driver but they seem very
expensive.

By the way, is there such a thing as a general purpose screw or is it
a matter of a different type for each application? Up to now I have
used Screwfix's Quicksilver range. I only really use it for joining
bits of wood or with a wall plug. I'm running a bit low, is there
something better I should stock up with?
