Our take on the Mighty Max Battery 12V 100Ah AC Solar

The Mighty Max 12V 100Ah is a sealed lead-acid (AGM) battery built for solar storage, backup power and small off-grid setups. It delivers 100Ah at 12V, about 1.2 kWh, and its sealed design means no watering and safe indoor use. It is heavier and shorter-lived than lithium rivals, so it suits budget-minded buyers who need a simple drop-in battery rather than a long-term investment.

Questions and answers

Is this battery good for solar?
Yes for small, low-draw solar setups. It is a sealed AGM battery that tolerates partial charging better than flooded lead-acid, but it needs a charge controller set for AGM.
How does it compare with lithium?
Lithium weighs much less and lasts several times longer per cycle. This battery costs less up front and works with simple lead-acid chargers, so it suits tight budgets and light use.
Can I connect two in series for 24V?
Yes. Two identical 12V 100Ah units in series give 24V at 100Ah. Use matched batteries of the same age and charge them fully before wiring.
What charger does it need?
Use a 12V smart charger with an AGM setting, roughly 10A or more for reasonable charge times. Avoid old unregulated chargers that can overcharge it.
What is in the box?
The battery alone. Terminal bolts and nuts are usually included, but check the listing; chargers, cables and mounting hardware are not.
Where is the Mighty Max Battery 12V 100Ah AC Solar cheapest?
At Lowe's, for $189.82, as of our latest check.
