Product Highlights
- Multiple banks - a one-bank onboard battery charger rated a 5-amps - 5-amps per bank - for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries.
- Enjoy precision charging - an integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
- Redefined mounting - a simplified mounting system allows for quick and easy installations in any direction - even up-side-down - with an integrated anti-vibration backing to isolate shock, vibration, and noise.
- What's in the box - gen5x1 5-amp 1-bank waterproof onboard marine battery chargers (120-240vac) with a 72-inch dc cables with 3/8-inch eyelets and a 72-inch type-b ac cable, (2) self-tapping mounting screws, user guide, and 3-year warranty.
- Meet the gen5x1 - similar to our genm1, only better. it's 37% smaller and delivers 43% more power. it's one of the best performing onboard marine battery chargers we have ever made.
- Charging modes - independently charge and control each battery bank with selectable charging modes - including 12v, 12v agm, 12v lithium, and 12v repair mode - for all types of lead-acid and lithium-ion batteries.

Product Highlights
- Do more with genius - designed for 6-volt and 12-volt sealed lead-acid automotive, marine, rv, powersport, and deep-cycle batteries, including flooded, gel, agm, sla, vrla and maintenance-free, plus lithium-ion batteries (lifepo4).
- Charge dead batteries - charges batteries as low as 1-volt. or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts.
- Beyond maintenance - it's not just a battery trickle charger, it's an advanced battery charger maintainer. a fully-automatic, worry-free smart battery charger for everyday use - 24/7 - with zero overcharge.
- Meet the genius5 - similar to our g3500, just better. it's 34% smaller and delivers over 65% more power. it's the all-in-one universal charging solution - battery charger, battery maintainer, trickle charger, float charger, plus battery desulfator.
- Enjoy precision charging - an integrated digital thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
- Restore your battery - an advanced battery repair mode uses slow pulse reconditioner technology to detect battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life.

Product Highlights
- Ambient temperature sensor – installed temperature compensation precisely adjusts battery voltage based on temperature sensor readings. this ensures your battery will always be properly charged and maintained no matter what conditions it is subject to. reverse polarity, short-circuit and over temperature protection.
- Includes – included in the box is model 2012-agm, an installed ambient temperature sensor, 2’ battery clip cord with quick connector, 2’ fused ring terminal, and a 6’ ac and 6’ dc cord.
- Extended battery life - automatic full time desulfator reverses sulfation (a buildup of lead sulfate crystals) the primary cause of early battery failure by using a patented range of high frequency pulse desulfation (not high voltage) to safely remove sulfation and recondition weak 12v agm batteries. sulfated batteries once considered beyond recovery can now be brought ...
- Six batteries at a time - maintains up to six 12v agm batteries (of the same type) at a time when connected in parallel. requires the use of y-connectors 210ay (sold separately). intended for high-performance agm sealed batteries such as odyssey, hawker and other agm batteries that contain pure lead thin plate technology (plt). worldwide 100-240 vac 50/60 hz input.
- Fcc certified - certified by the california energy commission as meeting the current efficiency standards which means it meets strict energy efficiency guidelines set by the us environmental protection agency and the department of energy.

Product Highlights
- Precise charging with two 12 volt and 24 volt charge modes, dialling in the right charge level for flooded batteries, sealed agm and gel or lead-calcium ca-ca batteries.
- Charging is fully automatic and worry free. ampmatic charge control with built-in temperature compensation automatically adjusts charge rate according to battery size and condition and ambient temperature, guaranteeing an optimal charge every time.
- Designed to optimize performance and extend life of 12v and 24v deep cycle batteries in your rv or other craft, also works great for any starter battery in cars, pickup trucks, atv or motorcycle.
- Your charge mode selection remains in memory even if the ac power is lost or battery is disconnected. safe selection ensures you don’t accidentally charge a 12v battery if you previously selected a 24v mode.
- The automatic 8-step program saves a deep discharged battery from as low as 0.5 volts and the accurate pulsing absorption completes charging to 100% without gassing followed by long term maintenance mode that keeps the battery at its optimal level 24-7.
