Let the buyer beware!

<p>I bought eight Omnipower OPS 12-260 batteries, after nine months the UPS system started playing up, it took me three months to pinpoint the problem to two faulty batteries. Sinetech wouldn't even touch the batteries. Their Mekoa Lekalakala told me nobody ever had problems with Omnipower. What a lie.</p> <p> </p> <p> I forcefully removed the top covers, only to discover that some of the rubber vent caps were lying loose next to the breather holes; the cells bled bone dry! Definitely a factory defect. I will never ever buy from Sinetech again.</p>
