Be careful Purchasing Deltec Batteries

My Brother kindly gifted us a 24v inverter with 2x 12v 105ah deep cycle batteries for Christmas to power the TV and computer during loadshedding. When I was at the shop, I was taken through everything with the shop consultant. They also set it all up for me. I was told the average lifespan of the batteries was 2-3 years at 300 cycles. I was completely shocked to see that my batteries lasted a year. I was told by other people that are in the business of solar energy etc that these batteries should have lasted longer. So I approached deltec with my batteries and initially they kept repeating over and over again about the 300 cycles and because there has been stage 6 loadshedding a few times this has had an affect on the battery life. Now remember, we are under the City of Cape Town with loadshedding. The majority of loadshedding in the past year has been only stage 2. Yet again, like a broken record they kept repeating the mantra of 300 cycles etc etc. They then sent the batteries back to deltec for them to be inspected. Now, I knew this would be a futile exercise as they are not going to take responsibility... A trait that has become quite relevant in South Africa. Pass the buck and deny any responsibility. Although I was advised this would take 2 days, they took a week. Nonetheless, Deltec did give me a couple of batteries which were no good for holding a charge but at least I wouldn't have to worry about power surges damaging my equipment. They came back and once again had to listen to the same broken record. The branch manager popped in this morning to check my system at home to see if it was set up properly. Again, same story.

I have since investigated further online. I'm pretty shocked for what I have found. Companies selling the same Deltec batteries as mine, are saying they are only good for 200-250 cycles with a 1 year warranty. This is not what I was advised when the system was purchased. I was advised that 300 cycles and no mention of a warranty directly from Deltec on the batteries. It has come to light, that it was all a sales pitch to try and sell their product to me. Also the rating that these deltec batteries have received by consumers have been poor on some sites. My part in all this, is I should have done more research before I allowed my brother to purchase this product. Take it or leave it, but I advise doing your homework 1st. Very sad but expected, that deltec take no responsibility.
