Renology batteries

Capt Helges · Oct 28, 2024

Has anyone used Renology AGM batteries?
I'm looking to buy 4 more AGM batteries for my 51 Defever poc and saw they are half what I just paid for my lifeline AGM batteries and are advertised as direct replacements?
Thanks

Renogy has a wide product line of electrical stuff for boats and RVs. I have had good luck with them.

No one knows how long anything made today/this year will last, just guesses. Same with opinions on good/bad are based on past usuage, not current model.
I have 8 Renogy 100Ah LFP for almost 2 years and still happy with performance. After research the Will Prowse disection and approval closed the deal.

ETA: But buying them today may offer different opinions. As we all know once a successful product North American product is farmed out to chinese cheaper construction, quality suffers.

Rod Collins is highly respected in the community. In the past, like me, he doesn't have much good to say about Renogy.

However.......@DavidM has my respect. He's pushed back on me about Renogy in the past. He hasn't converted me, but has softened my stance. That said, I look to Will Prowse YouTube reviews for dependable information as he has a large following who feedback information in addition to his tear downs (not sure if he's ever done a renogy test down). Tough to argue against that.

Amazon has the Renology 100ah for $189. I just bought a pair of no name dual purpose 900cca 95ah AGM’s for $149each. That includes shipping. I can’t even buy FLA this cheap.

My house is LFP. These batteries are for my thruster bank.

I would pretty much take Rods opinions to the bank. He does great work. Marinehowto.com

I believe rod was referring to lithium and or their electronics?

I put a cheapie Renogy solar system (100W panel, PWM controller, 20AH LiFePO4 battery) on my shed to run the 12 volt lights in the shed and also the attic ventilator fan in the house. Five years, still running.

Yeah, it's cheap stuff and it looks that way. But hey, 5 years is 5 years eh?

Marine How To & Renogy
Read the comments from Rod and decide for yourself. These articles were probably valid the day they were written, notice they are not time stamped. In any event Rod has a bias against Renogy as there are many others in the USA like Renogy and they are not mentioned by name.

I know many uneducated battery buyers buy Renogy thinking all AGM’s are the same. Nothing could be further from the truth.

I don’t often do this as I hate to ever advise against any manufacturer but there is one manufacturer that we would urge a very strong caution on and that is Renogy. We’ve not seen a manufacturer with this many failure prone products in 30+ years

The safety of knocks-offs can be scary and they CAN CAUSE FIRES due to hot spots. Renogy, one of the Chinese made knock-offs, had a recall due to fires.

We do not make cheat sheets for batteries sold by “sticker application companies” such as auto-parts stores, West Marine, Costco, or cheaply made off-shore batteries such as Renogy or most any non USA made battery sold on Amazon.

Now,
Where are LiFePO4 cells manufactured?
Made in the USA & Assembled in the USA is not the same thing.

I have Renogy flex panels, charge controller and battery monitor on my boat. I don't think I'd trust their batteries personally. The flex panels failed and were replaced under warranty after some struggle (2 years old). The monitor display failed and they wouldn't replace (2 years).

I think they're good semi-disposable units to help you get yourself configured, but batteries are mission critical and I wouldn't trust them from Renogy.
