Buying Guide: What to Look For
-
Inverter Type: Always opt for Pure Sine Wave inverters. They provide “clean” electricity similar to the grid, which prevents humming sounds in fans and protects your expensive gadgets.
-
Capacity (VA vs. Ah): VA (Volt-Ampere) tells you how many devices you can run at once. Ah (Ampere-hours) tells you how long the battery will last.
-
Warranty: Summer puts a high strain on batteries. Look for products offering at least 36 to 48 months of warranty for peace of mind.
-
Maintenance: Traditional tall tubular batteries require periodic distilled water top-ups, while Lithium options are maintenance-free.
Pro Tip: To extend your backup time during an outage, turn off non-essential items like heavy decorative lighting or extra fans in unoccupied rooms. Even a high-capacity battery lasts longer when the load is managed smartly!
