Prime 12v battery dead

AI Overview:



"Inflammable" means the same as "flammable"—it describes something that can be easily set on fire. Despite the prefix "in-" sometimes meaning "not" (like in "invisible"), in this case, it comes from the Latin "inflammare," which means "to set on fire" or "to put into flames"

 

Since we need more confusion here is the Amazone description

"NOCO GENIUS2: 2A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries"

 

Well maintainers are trickle chargers. They just have the means to not overcharge a full battery.

 

Exactly. Search engine optimizer - use the terms someone is likely to use based on their age and expertise.

These days any low cost charger has logic to prevent overcharging.

Harbor Freight's under $10 charger is safe and often sells for less than $5.



Only grandpa's rusted tool collection may have an unregulated charger - which in most cases won't impact an agm battery but is not great for vehicle ecus.

The real killer is high parasitic draws allowing a full discharge of the 12v battery, often caused by aftermarket additions. Sometimes car manufacturers have code bugs causing high draws but even those are resolved if the owner gets the update.

 

It can say whatever it wants in the description, but Noco Genius is not a dumb trickle charger, which charges the battery indefinitely with a small current. It will stop charging altogether when it thinks the battery is fully charged. It will not restart charging until the battery SOC drops below a certain level (in about three days with Gen 4/Gen 5 Prius). The point was that you don’t want a dumb trickle charger that is always charging.

 

Right, Amazon is the ultimate source of correct descriptions.

 

"Trickle charger" is just what's most familiar to most buyers. The accuracy of the description is not a priority to whoever writes it.

 

I had a cheap battery maintainer in my Gen 3 Prius. It cost me $5 on clearance.
It worked just fine for when my car was parked for more than a week. It had a constant 50 mA drain, which was good for about 9 days before the car wouldn't start.
The reason I went with a NOCO on my Gen 5 was because I didn't have to open the hood to turn it on when I plugged it in.
