Voltage, current, and battery construction will all be a deciding factor in how much energy a battery can deliver, and how long it can deliver it for.

i used to think exactly that, i had 3 cheapo drillls, bought the first one from macro, replaced after complaining for similar priced other make, and aquired another of similar pruce and quality. All failed due to shite battery/charger combination, either the charger continued to charge the battery until it cooked it, or the battery just gradualy stoped taking charge until it stopped working, all 3 where dead in 3 months, all 3 had useable battery life that was conciderably shorter than than charge time to make it work in the first place.

So my advice, if it dont have lithium iron batterys then dont buy it unless you want to buy another one in 3months weather its used or not. So ask yourself how many "3months" will go buy before you could have paid for a decent lith ion equiped drill that will last for years, or 2years 6 months so far in my case.... light use counts for nout.

Any cordless drill or saw etc is only ever as good as the battery set with it, and will cost more to replace the failed battery than the whole set cost in the first place at that(cheap) price range....imo lithium iron minimum requirment.

Voltages and battery capacity tells you nothing about how powerful a drill is in use. It's pure marketing speak on the box, chosen for exactly that reason.

A 240v motor from a clock I could stop with one finger. The 12v starter motor from my Omega would probably rip my arm off.

I have a couple of Bosch cordless drills and have always found them fine.

Bought a Rockworth 18V 1.3Ah from Makro a couple of years back.  Don't use it all that much - odd jobs only.  It's done everything needed so far, battery retains charge even if not used for 3 months.

Comes in good case with drills and screwdriver bits. Only cost £20 + VAT.  Highly recommended.  Don't know if they're still available, though.

Only thing I've had hassle with on the Bosch drills is the quick release chucks. I've replaced mine with good old-fashioned Jacobs jobs.

Not an issue with an SDS drill, of course.

Ryobi is nowhere near the same ballpark as Bosch.
In fact, they are so far apart in terms of performance & longevity that it's not even the same game.

14.4 Cordless Dewalt user for past 2 years. When I work on the car I take it out before even thinking of firing up the compressor. Works great
