Recently, our house battery was clearly on its last legs, barely lasting a night. Te Moana had two 140 Amp hour (Ah), giving it a total of 280Ah. When I started looking for a replacement, I was taken a back by some of the prices I found for direct replacements (approx A$2000).
After a bit of Googling and phone calls, it was clear that Chinese battery manufacturers are establishing themselves and that there were some good deals to had. In the end I settled for three 100 Ah sealed AGM batteries from FullRiver. I ordered them from a small company in South West Sydney , All Purpose Batteries in Narellan and went to pick them up.
He was out of stock of the 100Ah units and I ended up with three 110Ah units in stead, giving Te Moana a healthy 330 Ah capacity for a total outlay of A$870.
As you can see on the left, the three new batteries fit approximately the same space as the two original batteries.
I purchased another set of battery leads to be able to parallel up all three units and with a few small mods to Te Moana's battery compartment, we're back in business.
The next project is to look at fitting Solar Panels to help keep the batteries charged.
