Charging AGM battgery


Gadgetman

Question

was in my local auto parts store recently and looking at AGM batteries and was told that I would need a special charger to charge them with. Anybody heard of this before? Will my normal 10 amp deep cycle charger do the job ok?

You may need a new one. The onboard charger I have is a 7 year old Dual Pro. I just checked with the manufacturer and they said it would work OK with all AGMs on the market today. I had a specific question about Cabela's AGMs which have a label on them describing some charger requirements. Try and check with the manufacturer of your charger.

you will need to trickle charge using 2amp mode only and will take a long time to charge. Hope this helps! grin.gif

I disagree. A charger with an AGM curve would be ideal, but not absolutely necessary - nor is a 2A charger a necessity.

What is an "AGM curve" does that mean that my normal charger is good enough or not?

I have a optima and a cabelas AGM and I am charging them with a 2 bank Guest 20 amp (10 amp per battery) charger. The guest manual says it's safe for sealed batteries. Am I doing something wrong?

My new smart charger has a selection from wet,gel to agm. I know between gel and wet their is a diffence. I would go with correct chrager for maxium life of battery. The charge cost's as much a battery. I finally laid to rest my 1982 craftsman trickle charger and bought a new one. Good luck!

P.S.

Still have it though!

You can use your 10 amp deep cycle charger for AGM batteries.

Like shachbash said the smart charger is probably the best option but they cost a lot.

      Very low, probably 2 feet lower than last year at ice out.

      what do they look like this spring?

      I might have missed a guess, but here are the ones that I noted:   JerkinLips – March 27th, then April 7th Brianf. – March 28th Bobberwatcher – April…. MikeG3Boat – April 10th SkunkedAgain – early April, then April 21st   Definitely a tough year for guesses, as it seemed to be a no-brainer early ice out. Then it got cold and snowed again.

      MN DNR posted April 13 as Ice out date for Vermilion

      No, that wasn't me.  I drive a 621 Ranger.

      On the south end...   Lots of ice on the main basin, but it is definitely deteriorating.  Some anglers have been fishing the open water at the mouth of the Rainy River in front of the Lighthouse Gap.  The rest of the basin is still iced over. Pike enthusiasts caught some big pike earlier last week tip up fishing in pre-spawn areas adjacent to traditional spawning areas.  8 - 14' of water using tip ups with live suckers or dead bait such as smelt and herring has been the ticket.  Ice fishing for all practical purposes is done for the year. The focus for the basin moving forward will be pike transitioning into back bays to spawn,  This is open water fishing and an opportunity available as the pike season is open year round on Lake of the Woods. The limit is 3 pike per day with one being able to be more than 40 inches. All fish 30 - 40 inches must be released. With both the ice fishing and spring fishing on the Rainy River being so good, many are looking forward to the MN Fishing Opener on Saturday, May 11th.  It should be epic. On the Rainy River...  An absolutely incredible week of walleye and sturgeon fishing on the Rain Rainy River.     Walleye anglers, as a rule, caught good numbers of fish and lots of big fish.  This spring was one for the books.   To follow that up, the sturgeon season is currently underway and although every day can be different, many boats have caught 30 - 40 sturgeon in a day!  We have heard of fish measuring into the low 70 inch range.  Lots in the 60 - 70 inch range as well.   The sturgeon season continues through May 15th and resumes again July 1st.   Oct 1 - April 23, Catch and Release April 24 - May 7, Harvest Season May 8 - May 15, Catch and Release May 16 - June 30, Sturgeon Fishing Closed July 1 - Sep 30, Harvest Season If you fish during the sturgeon harvest season and you want to keep a sturgeon, you must purchase a sturgeon tag for $5 prior to fishing.    One sturgeon per calendar year (45 - 50" inclusive, or over 75"). Most sturgeon anglers are either a glob of crawlers or a combo of crawlers and frozen emerald shiners on a sturgeon rig, which is an 18" leader with a 4/0 circle hook combined with a no roll sinker.  Local bait shops have all of the gear and bait. Up at the NW Angle...  Open water is continuing to expand in areas with current.  The sight of open water simply is wetting the pallet of those eager for the MN Fishing Opener on May 11th.   A few locals were on the ice this week, targeting pike.  Some big slimers were iced along with some muskies as well.  If you like fishing for predators, LOW is healthy!

      Early bird gets the worm some say...   I have it on good authority that this very special angler caught no walleyes or muskies and that any panfish caught were released unharmed.
