Direct Replacement for Genio E300–E355

This Cameron Sino battery replaces the original cell in Genio E300, E310, E330, E335, E340, E350 and E355 jump starters. It restores starting capability and portable power for automotive and workshop use. The pack fits the exact footprint and connector layout of the factory unit. Users needing a different voltage or a higher capacity must choose another product.

Chemistry and Safety Limits

The pack uses the same lithium chemistry as the original and includes integrated protection against overcharging and short-circuiting. It delivers the rated voltage and current the Genio firmware expects, so the charger and jump-start functions behave identically. Exceeding the device's specified cranking current or using an incompatible charger will trip the safety circuit or damage the cells.

Simple Swap, Common Pitfalls

Installation requires opening the jump-starter case, disconnecting the old pack and connecting the new one to the existing header. The connector is keyed, but forcing it can bend pins or crack the housing. A frequent issue is forgetting to reseat the case gasket, which compromises splash resistance. Verify polarity before the first charge cycle.
