My batteries were 2008 lead acid models and had given up the ghost after 8 years. I replaced them with 2 x Hubble S120 in 1921 and been a happy camper ever since. They handle 2 x 4,5 hour load shedding (11,5-hour session) with 2,5 hour charging in between with a smile on a 250W to 300W load. I charge them with 30A.
I unfortunately had to modify my battery box handles to accommodate the longer S120 batteries.
