About Mighty Max Battery ML9-12NB 12 Volt 9 AH Rechargeable SLA Battery
Overall Feedback:
83% positive
81% praised the high capacity
The battery arrived fully charged with the advertised capacity of 12 volts 9AH.
I checked the battery capacity after 3 weeks of charging and found it holding 13.4v.
84% appreciated the compatibility, though 16% experienced issues
The battery arrived quickly, was fully charged, and ready to install. When I put it in the machine, it started right up.
I couldn't charge the battery as the charger wouldn't accept it.
82% were impressed with the long cycle life
I am not sure about the battery's longevity yet, but it is less expensive than the Generac original replacement battery and starts the generator without any strain, even during cranking.
82% liked the maintenance-free design
I wired leads directly onto the battery to keep it plugged into a maintainer for the winter.
After 36 hours of removing it from charging, I can confirm that the unit is still showing full charge and all functions are working perfectly.
I replaced an aging 7Ah battery with this one without any modifications needed.
66% appreciated the safety features
I replaced an aging 7Ah battery with this one and had to modify it. I used screws, terminal bolts, and adhesive foam sheet to give it the same protection as the original battery. It worked right away.
81% were impressed with the lightweight design, while 19% weren't
I cannot provide an experience-rich sentence about the weight of the 12v-batteries as I have not mentioned anything about it.
