    Nothing but gels in all my bikes for the last 12 yrs or so. Cost about the same as lead-acid, no special charger and lasts twice as long. And no chance of leaks.

    Huge shout out to Anti-Gravity.

    I have a 5 year old Micro-Start Mini, long after the warranty expired, and the case had swollen and popped up. Still worked ok, just had me concerned.

    The gave me 30% off the price of a new model, so I jumped on that and a new harness for a new bike I bought that allows jump starting from the SAE charge cord.

    The package came today and much to my surprise, there were some extra goodies thrown in. An audio cap and a lantern/light/speaker power bank.

    I really like these great folks. Tremendous service and awesome to deal with.
    Buy their stuff !!

    We have an old (2014) PPS. It has a different size charging jack than our newer ones.

    What 120V charger do we order?

    It's a discontinued Micro-Start model and unfortunately we no longer offer the replacement charger for the PPS. We apologize for the inconvenience.

    If you give us as call at (310) 527-2330 we can discuss possible replacement options for the unit.

    I've used standard lead acid for about 10 years but recently went to AGM. My understanding is that there's no need to trickle charge an AGM over winter, but here's a couple questions for the obviously very well educated battery experts here...
    1. Where I live, "winter" can mean a good 5 months of no riding, can I still just leave it?
    2. If/ when I do recharge, should I take the battery off the bike?
    I'm sorry if this has been covered already, there's just too much in this thread to wade through :)

    Lots of opinions I'm sure. The way I like to do it is check voltage across the battery every couple weeks when not riding. A fully charged AGM will be about 12.8v. No reason to charge or otherwise "maintain" a battery that is fully charged. If/when your voltage checks at 12.4v or less, that means the battery has dropped to 75% of charge and a good time to put a small charger on for a few hours, then remove.Repeat checking same way all winter and charge only as needed.
    I know there are many that strongly believe in leaving a Battery Tender on 24hrs a day. I don't believe in it myself so many contrasting views.

    Glad you brought that up because advertisers claim that AGMs have a very low level of self-discharge. That is true when they are sitting on a store shelf and not connected to anything. The trouble is, when they are connected to a vehicle, numerous systems (alarm, ECU, etc) draw current that far exceeds the self-discharge rate of the battery...tens to a hundred of times more. So the self-discharge aspect means nothing when it is connected to the vehicle.

    1. I would at least monitor the battery voltage and charge it when necessary. Better still, connect it to a battery maintainer and not worry about it.
    2. If possible. Note though that indoors where it is warm it will self-discharge a bit faster than in a colder environment. If it is below freezing, I'd make sure the battery is fully charged first and then keep it that way. The last think you want to do is charge a frozen battery with any substantial current.

    Pretend you are riding it. Every weekend, walk into the garage and connect the QD battery tender leads. Sometime later that day or weekend, disconnect. Simplest method.

    If you are not going to ride it for 5 months, do what the Manufacturers suggest.
    Fully charge at the end of the season with a proper charger (not a trickle charger)
    Disconnect and come back in Spring.

    Battery charges I own and use (not that these are the best or cheapest). None of these is a trickle charger. Information obtained from the manufacturer's web pages.

    Don't class myself an expert i'm always learning (leave that to the yanks there good at trying claim the fame LOL)
    Just speaking from experience
    Still need to trickle charge AGM just threw out a new AGM as it sat on shelf for 12 mths no trickle held only 16Amp

    As soon my bikes home there on trickle 950SE just replaced the Motobatt AGM after 6 yrs

    Its not my experience.
    Theres no need to charge a battery every week, the charger should cut of in a matter of seconds doing that, if theres no parasittic draw.
    Have alook at the output of your charger, then time how long the charger runs, and you know roughly how much capacity the charger "filled up" the battery

    If there’s no parasitic draw is important here. What you want to do with your battery will depend a lot on how much (if any) parasitic draw there is.

    Exactly
    I have a rally tower on 2 x bikes with nav equipment & Accessories on other with isolation toggles there is still a small amount of draw

    Motobatt recommended to put my AGM motobatt batteries at least on trickle once a month if not in use
    As i said i got 6 yrs out my batteries using trickle once bikes are parked home. my bikes are daily rides not weekend toys

    I'm no battery expert. My last AGM lasted nine years, and still has two thirds of its original capacity. It got disconnected & removed from the bike every winter, and fully charged at the beginning of that storage period. No trickle charging.
    1. My understanding is five months should be fine if there is no parasitic drain, i.e. the battery is disconnected from the bike. I recently installed a main switch for this purpose, and posted about it.
    2. I don't think that is necessary, since you are not going to push the battery beyond 14.8V, and the bike electronics should be ok with that.

    I've got a kick start only bike with a big 12v sealed lead acid battery to run the lights and such. Could I get away with just throwing in a Milwaukee m12 lithium battery in its place?

    Which biked do you have?

    I would think it depends on how you are going to charge it. If you are going to remove it to charge it, I would think that would be fine, though also a hassle. I would not charge a lithium battery directly from the bike unless the battery has some sort of built in charge control.
