Pocket Multimeter

basically used straight away, as my other two seen better days, especially recieving a new battery, delivered with 10.76 volts, van had 12.71. so i charged this new battery, with 4 yr warranty, after a full charge, let it settle, 20.88 registered on new meter. think i was sold old stock, or brand new second ! but with out that i may have put staright on van, and wondered why it wouldnt start !!!! got my money back and they said i could keep it. only good for ? good scrap value
