Thank you although I don't understand 90% of what you said. .
I'll see if I can't give the battery back and maybe get a new one since it shoukd still be under warranty. What is the best battery to get that should last?
Hi. I have a Mecer inverter 1200 with 1 battery. Battery is 6 months old and tested it yesterday, it is still fully charged.
When power goes off, the inverter shows that the battery is low and maybe lasts 15min before it shuts down. What can I do please?
