Hi,

It seems like the Schumacher brand doesn't get much respect, when doing a past search on this site.

Of those 3 brands (if all are indeed separate companies), which would you choose?

Looking for general charger, have some deep cycle marine batteries to maintain and any impending auto issues.

Thanks.

I currently have an older 6 amp Schumacher manual charger, just want to get something with a minimum of 10 amp charging.

None of the above, although I still have an old Schumacher and its fine for what it is.

My current pick is a Prologix Solar smart charger/maintainer. Has a very good 7-stage charge/desulphate/maintain profile that has resurrected batteries that wouldn't hold a charge for more than a day using the old manual Schumacher.

Also if you choose to leave a battery on it for months at a time, it doesn't constantly apply voltage like a typical "maintainer," which can lead to sulphation. It just monitors most of the time, then periodically will put a light load on the battery for a while, then re-charge it.

I've had my Schumacher for 12 years now not any problems. They have a pretty nice one at Walmart at the moment at least at my local store. Mine is 2/10 amp and an Auto/manual unit. The one at Wally world was pretty much the same $59.

I bought a 6 amp Stanley last summer and it worked pretty good until my brother hooked it up backwards to a battery (supposed to be able to take it, obviously can't). So I ordered the ProLogix that 440Magnum posted above. Really like this charger!

I have an older Schumacher buzz box identical to the one in the picture. I mostly just leave it on 10 amp mode, but sometimes use the 30/50 amp boost setting. It does the job for the most part. another bonus is if it's raining or snowing out and I need to charge a battery, I can just stick the charger under the hood. if I need more, I use the rolling battery charger that is 2/15/50/250 amp and 12v/6v. (Both chargers are fully manual, but I monitor both charging amperage and voltage)

Not on your list but I'm having good luck with BatteryMinder chargers (not to be confused with Battery Tender) They have settings for various battery types and a temp sensor that allows an internal circuit to adjust the charging rate to keep batteries from getting too hot while charging. They also have a desulfating mode that I question whether it actually works but they charge batteries very well. Adjustable for 2, 4, or 8 Amps which is a bit below your 10 Amp requirement.

An old iron-core manual or semi-automatic Schumacher is good to keep in the garage because it is best at (attempting to) revive a battery that has been run down completely dead. The fancy digital stuff often refuses to charge at all. Maintaining a battery in storage is a different situation that calls for a completely different machine.

I have experience with CTEK and Noco and have been happy with those.

Does anyone know if the Stanley and Peak are actually Schumacher? Just throwing out some common brands that I see at Walmart, Menards, Fleet Farm, etc.

I have to admit that Solar Prologic is tempting.... if I could save some money and get a reliable unit with these other brands, I would probably go in that direction.

I'm looking for a good solar powered battery charger. So this one isn't solar powered even though it's in the name?

Pretty simple way around that. Wire a battery with some charge in it in parallel with the dead battery and charger. Let the charger start working, then after a few minutes remove the extra battery from the circuit. The charger will take it from there. You just need some initial voltage to get the charger going.

+1. I own both, and both are good.
However, I prefer the CTEK, as I find it easier to use.

I have had the Stanley 25 Amp/75 amp charger now for about three years and it has been very reliable.

I would never buy another Schumacher as I have had two them that have failed and their specs are over rated.

Correct. I don't know why they put 'Solar' in the name, maybe the company started out making solar chargers.
