Frequently Asked Questions

Can this charger handle both lead-acid and lithium batteries?

Yes — the Genius 3.0 automatically detects and charges both battery chemistries without manual switching.

What if my battery is completely dead?

The Genius 2D includes force mode to charge batteries down to 0 volts, even when the charger won't detect them normally.

Can I mount this permanently on my bike?

Yes — the Genius 2D comes with a mounting bracket and strap for under-seat or frame installation. Use the detachable clamps to wire it directly to the battery.

Will it reverse-polarity protection if I hook it up backwards?

Yes — the smart indicator detects reverse polarity and shows a warning so you can correct the connection before charging starts.

Is this a trickle charger or a fast charger?

The Genius 2D is a 2-amp maintenance and recovery charger — ideal for conditioning and maintaining batteries during storage or between rides, not a fast charger for rapid charging.
