   I use 4Ah 18V (that's "badge-engineered" to 20V in the USA) batteries in   
   the SDS-drill I use for drilling sockets in granite.   
   Seems to work very well.   
   About battery size and finding that not the most massive battery seems   
   necessary to get performance which seems absolutely fine.   
      
   Have previously asked on r.c.m. when looking to set up this capability.   
      
   Are DeWalt drill and battery.   
   Is DCH263.  Largest drill using "small tool" batteries (?).   
      
   Drill is best no pilot drill to 12mm into hard granite including elvan   
   (very hard fine-grained dykes where magma has infilled fissures in   
   previously solidified granite).  14mm there might be an advantage in   
   pilot-drilling - not less than 7mm because the drill over-powers   
   anything smaller and melts the tool - but not more than 8mm - seem to   
   want to pilot at half the final drill size.   
   Talking about carbide-tipped masonry drills.   
      
   4Ah does quite a lot of holes.   
   Working hard breaking rocks, get through 1~1/2 4Ah batteries in 3~1/2   
   hours.  That's both drilling sockets and using the feathers-and-wedge   
   sets to break-up boulders.   
      
   Locally the price for 18V DeWalt Li-ion batteries is GBP13 per Ah.   
   Had 4's but no 5's, so as price is pro-rata here, got another 4Ah.   
      
   Coming back to your point - the batteries seem just fine, and I let you   
   be the judge of that by describing the work they do.
