Fronus FR-2204 Pro Max Tubular Battery 220Ah Price in Pakistan

The Fronus FR-2204 Pro Max is a 12 volt, 220Ah tubular battery from the Fronus Pro-Max VRLA Tubular series. Its standout point is the listed warranty of 30 months, longer than many flooded tubular batteries in the market. The series name says VRLA, which stands for valve-regulated lead-acid, a sealed design.

At 220Ah, our formula (Ah x 12 x 0.5 x 0.85 / watts) gives about 1122 usable watt-hours. On a 300W load of fans, lights and a router it runs for about 3 hours 44 minutes. On a 600W load with a fridge it runs for about 1 hour 52 minutes. We use 50 percent depth here too, as that is what keeps lead-acid batteries healthy over many cycles.

It is a good match for 12V solar inverters of 1 to 1.5 kVA, and two in series suit 24V hybrid inverters of 2 to 3 kVA, including Fronus inverters. The charger or solar controller should give around 22 to 33 amps. Because it is a sealed design, set the inverter to the battery type the maker recommends rather than the flooded profile. The plate count is not listed, so check the datasheet if you need it.

Maintenance is lighter than with flooded tubular batteries. A VRLA battery is normally not opened for water, but please confirm this on the label when it arrives. Keep it in a cool, shaded spot, since heat shortens the life of every lead-acid battery, and keep the terminals tight.

The 30 month warranty is listed; ask for the warranty card and terms with your order. Life depends on depth of discharge, heat and charging settings. Only two shop listings were found for this model, so the live price on this page is the best guide. Compare it with flooded tubular options on our tubular battery page (Tubular Battery), or see the full brand range (Fronus Battery prices). Lithium is the next step up in usable capacity (Lithium vs Tubular Battery: Which Is Better for Solar?).

On arrival, check the label date and battery type, and register the warranty if the brand asks for it. Syed Non Custom Solar sells the FR-2204 Pro Max and shows its current price here.
