I bought an 18v Ozito reciprocating saw from Bunnings ,used it once, fantastic, tried to use it 4mths later the battery would not charge properly and did not last.I tried to take it back to Bunnings but the reciept was unreadable and I was told I should have Photocopied it as this happens all the time.Not happy. I have approx 4 other Ozito tools and I cant find where to get a replacement battery for this one.
