Battery charging ?

I have flasher and camera batteries that are 7, 7.2, 8, and 9 amp. I'm currently using 3 chargers, outputs are listed as DC 12V 850mA, 12.7VDC 550mA, and 12VDC 500mA.

Do all these chargers work with all these batteries?

The 500 and 550 are painfully slow at charging but eventually get the job done. The 850 is really fast but may have ruined the only 2 batteries charged. The 850 worked fast and well when plugged into the battery cover with the fitting on the camera the 1 time I tried it. I normally remove and leave off the battery cover as I need to change batteries after 4-6 hours of use and its a pain in the butt with the cover on.

The 850mA came with a new aquaview camera that I just returned for moisture in the camera, I forgot to include the charger with my return. I cut the fitting off the end of the charger so i can hook it directly to the batteries (this might be my problem). This charger seems to have shortened the running time on the 2 batteries charged with the 850mA. Its possible that both are at the end of their life but it seems like to much of a coincidence that both lost some life at the same time after using this charger.

I just purchased a new 8 amp and I'm very reluctant to charge it with the 850.

Please help!

The Charger's amp rating is only indicating how much amperage it can deliver. When you're charging your batteries they will take what they can take up to the limits of the ability of the charger. The output of the charger is not hurting your batteries. Overvoltage will damage your batteries. Make sure the chargers you are using are rated for the voltage of your batteries.

Finally, battery type is important. If you are batteries are NiCad make sure you are using a charger designed for recharging NiCad batteries. Likewise, Ni-mh batteries must be recharged with a Ni-mh charger.

Those batterys are sealed lead acid core batterys like car batterys not nicad or ni-mh.

For the past 3-4 years, I have used a 6amp charger for all my flasher and camera batteries and it has worked fine.

I have not had very good luck with the chargers that come with the units so I just went to this charger and it lasts and charges the batteries to a full charge and goes to maintain when they are full so they do not overcharge.

      Problems with Yetti

      By rundrave · Posted

      got this tackled today took about 3 hours to get both sides done. Didnt even get to use a torch....   Thought I was golden with just jacking it up and I could get to everything but no luck. Had to remove the entire axle hub and brake assembly to get to what I needed. Was a pain but still better then taking off the entire pivot arm.    Axle bearings were already greased and in great shape thankfully. Got both leaf springs installed and its ready for the road again.   Probably going to have my electric brakes checked, I am not touching anything with the brake drums. Based on what I saw it doesn't look like my electric brakes have been working anyway. Brakes are nice to have if its slippery out

      It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.
