Do u know???

All along, i know that cannot use the very powerful battery for clock usage, eg Energizer.. so i always buy cheap cheap batteries for clock and din bother wat colour. Apparently, there are different colours cheap cheap batteries.. So i anyhow use... Today bought a new clock, cos old one spoilt.. the lady boss told me MUST use the RED colour cheap cheap battery. Regardless whether its small clock or wall-hanging big clock, even if its $100+, also cannot use any other more powerful battery, else the clock will spoil... aiyo.. din know that oh... I think alot ppl also wont know ah.. So rem to buy the below type for clock...

Other colours batteries are for torch light or radio etc... Aiyo, then i saw my drawer got lots of "wrong batteries".. sigh.. buy too many cant use liao...
