Strong battery with responsive support
This battery performs well and comes with helpful customer service. When a terminal overheated during a 780-watt inverter draw for 15 minutes, support suggested poor contact and sent a replacement battery within days. Two terminal bolt lengths are included; using the shorter bolt may reduce contact area, so the longer bolt is recommended for better overlap. Despite the overheating, performance was strong, using only 13% of capacity for that run. It fits an RV group 24 battery box and is a notable upgrade over the original lead-acid deep cycle battery.
Pros
- + strong battery performance
- + responsive customer service
- + quick replacement sent
- + fits RV group 24 battery box
- + upgrade over lead-acid deep cycle
Cons
- − terminal overheated during high draw
- − shorter terminal bolt may reduce contact area
