Skimping on batteries often results in repairing a burned-out circuit board. A genuine battery is the ideal choice, but if your budget is limited, it's wise to choose a certified factory replacement. Technically, Deji battery is in no way inferior to the original components: they offer stable voltage, full system compatibility, and chips that don't require resoldering. Plus, they offer up to 30% higher capacity than the standard version, and overcharge and deep discharge protection works as expected. They reliably last 500–800 cycles.
