    • 🌟🌟🌟🌟🌟 Surprisingly Lightweight Yet Powerful A Reliable Battery for My Trolling Motor
As someone who uses a trolling motor regularly for fishing trips, I’ve gone through my fair share of marine batteries. This Newport 12V 50Ah Deep Cycle battery impressed me right out of the box. First, it’s much lighter than traditional AGM or lead-acid batteries I’ve used before easy enough to carry with one hand, which makes loading and unloading from my boat or vehicle much less of a hassle. Performance-wise, this battery delivers steady, consistent power. I ran it on a Newport 55lb thrust trolling motor and got a solid 4+ hours on moderate speeds with some bursts at higher throttle. Voltage remained stable the whole time, which means the battery didn’t sag under load like some cheaper options tend to do. Build quality also seems solid tight casing, clean terminals, and no noticeable heat build-up during extended use. It’s sealed and maintenance-free, which is a must for anyone who doesn’t want to deal with checking water levels or corrosion issues. One small point to note: there’s no built-in charge level indicator. I solved this by adding an external voltage meter, but it’s something to keep in mind if you like having that convenience. Overall, this battery strikes a great balance between weight, capacity, and price. It’s not the cheapest out there, but the portability and reliability make it a solid investment for serious boaters, kayak anglers, or even off-grid solar setups. Highly recommended. ... show more

    • Amazon paring the incorrect charger.
Although a great charger, do not use the Noco Genisu 1 1a 6v/12/v smart battery charger will not maintain or charge the Newport 12V50Ah Deep Cycle Heavy-Duty AGM marine battery. It will only charge up to a 30Ah deep-cycle battery. This is not easily known in the product description, and Amazon unfortunately pairs this item with the Newport 12V50Ah Deep Cycle Heavy-Duty Marine Battery, Lightweight & Sealed AGM, Trolling Motor Compatible battery. Very disappointed. The battery is great though! ... show more

    • No terminal posts included.
No terminal posts included. I was not able to use this battery at all, standard 12V battery terminal posts I use with my other two batteries don't fit, and as far as I know manufacturer does not specify what terminal post work with this unit, so I had to return it. Very disappointing experience, will not purchase this brand in the future. ... show more
