Desulfators

Featured Replies

Hi All

 

I have a few Royal 12v 105Ah "batteries" showing at 12.7volts or there about, at rest. Plug a lightbulb onto them and there is no amps after about 15 minutes.

 

Im considering buying a battery desulfator (ctek vs optimate)

 

Anybody with personal experiences to share? Are the batteries gone? Can they be revived? Which is a better desulfator etc

 

 

Thx

I have used my C-tek for quite a few years, but was used for car batteries. It is only now that I am getting into the solar stuffs.

I have found that standard car batteries a-la Willard, Sabat, Varta etc usually easily given quite a decent life extension. The 7Ah "alarm system" batteries however usually don't give such good results.

1) Yes.
2) Nope.
3) The one where you say you will buy the XYZ desulfator IF the battery you want revived, has been revived to your satisfaction. Buy that one.

Yip that's the one. Lol

As far as I'm concerned, desulfators are a scam. Well, not entirely, I think they may provide a little extra life. Maybe. I get the feeling this is one of those products that people buy... and then don't review later because they feel a little ashamed of believing the hype (and they ended up buying new batteries anyway) 🙂
