Bad product and even worst service - stay away

Bought their omnipower batteries, only used them for 15 loadsheddings , pulling only 1 amp per hour load and they only lasted 9 months. The test engineer is rude and use every excuse to not honor the warrantee. The receptionist saying for three weeks that Chris the CEO would call me back as he is in a finance meeting every time you call - to this day no call. Don't buy anything from Sinetech.
