Q: Do axtra battery charger better than noco genius 5? axtra battery charger only cost $30

Noco Genius 5 amp battery charger will charge faster than AXTRA 3.6 amp. If you have two cars, you can buy two of AXTRA battery charger for one of the Noco 5 amp charger. Highly recommend AXTRA battery charger: www.amazon.com/AXTRA-Fully-Automatic-Maintainer-Motorcycle-Tractors/dp/B08T7V4VQC I am an auto mechanic for 33 years. I have been testing these two chargers for about 8 months so far. AXTRA battery charger has 3.6 amp and 0.9 amp for small, medium, large size cars and trucks. NOCO has 5 amp only. AXTRA is more adequate to trickle charge motorcycle, lawn mower and ATV.

Q: Should i buy two of axtra battery charger or one unit of noco genius 5 charger?

Well I'm in a unique position as I have BOTH chargers. The axtra charger works fine if you connect it and charge while watching it so to speak. The noco charger works flawless all the time. I have them both hooked to xtreme charger switching units right now. The noco charges fine when it switches to the next vehicle to charge on the switcher. The axtra works a few times then stops charging till you power cycle it. Someone mentioned in another answer than the noco only charges at max amps. This is a wrong. The noco trickle charges just like the axtra does when the battery is fully charged. Its annoying that I have to now purchase another noco charger for the 2nd switching setup since the axtra charger cant do the job so I'm out 30 something dollars on the axtra when I should of just bought two noco 5 chargers to start with. Live and learn. Sometimes a "deal" price wise isn't such a deal after all. So yes I would recommend one noco genius 5 charger over 2 or more axtra chargers :)

Q: How’s noco 5-amp battery charger compares to axtra car battery charger maintainer?

We believe the NOCO GENIUS5 is better. The new GENIUS Series - including the GENIUS5 - incorporates full-throttle technology that holds the maximum charge current throughout the bulk charge cycle. It uses temperature compensation via an external temperature sensor to alter the charging voltage based on the ambient environment, which eliminates overcharging in hot climates and undercharging in cold environments. It charges 6-volt and 12-volt batteries, including lithium-ion. It can be used for a wide variety of functions (recharging from any depth of discharge, maintenance, desulfation, etc.).

Q: Can I use this to maintain the charge in my car and leave it unattended for months during winter storage?
