Lalela Inverters only last 8 months - BEWARE!

I bought an inverter only 8 months ago and Lalela is saying that the batteries have reached their life cycle and must be replaced at an expense of nearly R4000 minimum. Their warranty is for 6 months and this helps them get around the fact that they're selling something that only lasts 8 months without warning. Disappointing for a South African product taking advantage of load shedding challenges for small businesses. A very expensive mistake.
