Fish Finder battery charger

What brand / model # fish finder battery charger do you use?

I use the Black & Decker charger (BM3B).

Battery Tender.  I have them already for my moto bikes.

i'm using this one from humminbird:

Antonio you can always go to harbor freights and buy a tender for cheap

I use this Triton EQ for its versatility since I have batteries of various chemistry and voltages for my various toys.

This works well, can charge lead acid, NiMH, NiCd, LiPo/LiIon, works off AC or 12v DC, automatic peak charging.

The Schumacher XC6 SpeedCharge 6 Amp Battery Charger gets good reviews and recommendations and is easy on the wallet.

I have the same as rockfish, and it works, but the Black & Decker looks like the slickest for the least amount.

aloha,

I am not a battery or charger expert. One person that is, says this about the Schumacher,

 "...its a 6 amp charger and will charge up a marine battery all the way for you.  Its very budget oriented.  Under NO circumstances would I go lower than a 6 amp battery charger.  DO  NOT buy 1 or 2 amp 'trickle chargers' EVER.  They are not intelligent and they usually end up destroying a battery PLUS they NEVER have the ability to bring a discharged battery back up.  This is also available at Walmart, at Sears under the Diehard brand, but at a higher price."

So it might be worth getting something that will both charge and maintain a FF or even a marine battery.

A 6 amp charger for a 7-8amp battery seems like a bit to much

Deltran Battery Tender Junior ... no complaints here. 

A 6 amp charger for a 7-8amp battery seems like a bit to much

It will tear these 7amp batteries up. You will get far less life out of the battery "cooking" it that fast. Whoever says that 1-2 amp chargers don't work and you can't get intelligent chargers that size is also wrong. And, battery tenders are not chargers. There is a difference. A tender is meant to keep a battery at whatever state it was left in. A trickle charger will keep putting power to the battery and overheat it also and cook it dry till it shorts out if you don't discharge it every once in a while, i.e. use it. . A charger will actually "fill" the battery back up. A tender will give a false positive and look like it charged the battery, when all it did was surface charge it.
I have a 1.5amp Vector smart charger that has kept all 5 of my batteries in great shape for over 3 years. I also have this charger which works well too.

I use this one on almost every battery I have now. FF to race car. Works great and the race car has not failed to start yet. The slower you charge a battery the better it will accept the charge and give it the best charge possible.

The ideal charging current is 1/10 of the AH capacity, so if you have a 7AH battery, you'll want to target a .7 A (700 mA) charge current.  I've used up to 2A chargers, although the one I use now is 1A I believe.

Yes a charger is not the same as a maintainer. He was saying that a charger that can do both is better to have since it will do double duty.
