The Optimate charger I'm using at the moment is the Optimate 2 Duo battery charger / maintainer. It has a 2A constant charging current. Is this OK for 24/7 connection to a motorcycle battery? Would the Optimate 1 Duo with 0.6A constant charging current be a better option? I'm thinking about longevity of the battery (sealed AGM) Thanks guys!
Do you really need to keep a trickle charger on it? I thought one of the benefits of Lithium batteries is not needing to keep them on a maintainer. I had a shorai lifepo battery on one of my bikes some years ago and never had it hooked to a tender.
I have both units mentioned. My 900st is on one and the 765 is on the other, both can be connected 24/7 and no issues. The cyclic charging will give what it needs so I wouldn't worry. Sealed AGM ( absorbed glass matting) isn't a lithium battery @zvezdah1 but I do like the Duo idea as I have in addition lithium batteries so the charger risk mix up is negated.
Thanks for that info. It's that 'real world' usage I was wanting to hear about. I need to buy another charger (too many batteries!!) so wondered if I should go for the Duo 1 or Duo 2 so sounds like either one will be fine. Thanks again!
Duo 1 gives less charge rate so as a trickle charger it makes no difference but is cheaper to purchase than a Duo 2. The Duo idea appealed because a normal charger can't be used on lithium. I gave my remaining non-lithium compatabile charger to my son, so that I couldn't mistakenly connect it up with my x2 chargers living next to each other on the wall.
The use of the term “trickle charger” in respect of Optimates is wrong. It is a battery tender, not a trickle charger. As such it can be connected 24/7 to a machine’s battery when not being ridden and will regularly test/charge the battery depending on what it finds during a test phase. Like @Eldon i have an older Optimate 4 and one of the newer Duo units connected to the bikes permanently. The fact that the Odessey AGM battery is still going strong on the Ducati after 15 years is proof that this strategy works.
If you want a battery maintainer that will work on anything - flooded, AGM or lithium, look at the Noco chargers. I have a Noco Genius 2 (about $50) that I use on the lithium battery in my DR650 every month or so during the winter. It's tiny and works great. The only drawback is that Noco uses a non-standard connector between the harness they provide for the battery and the charger lead, but they provide another harness with clamps for the battery terminal in case you want to use the charger on another bike. The Genius 2 has a two amp maximum rate, which is plenty for maintaining a battery, and there's a one amp Genius 1 (about $30) and a five amp Genius 5 (about $70).
Hi, Iv got a optimate charger that i don't use as i bought th Optimate 2 ?? that does my EFB car battery as well (Stop start). Ill see if i can find th photo of of th site and post... You see if it good for you and if so just P&P will be good. Here you go...
Yep totally agree @Baza and like I said on post 4, the cyclic charging mode of these devices overules any notion of trickle charging or otherwise. @Scoot65 do a bit of research and buy one, connect it up, forget about it and it will last you years. Making it lithium compatible adds a bit of future proofing and hopefully eliminates possible mistakes/fires

I think this will be useful for one of my other batteries, so can you pm me what the P&P will be? Cheers!
[QUOTE@Scoot65 do a bit of research and buy one, connect it up, forget about it and it will last you years.

My current Optimate 2 Duo is good for the bike and car (car is sometimes stood for a month or more each year) so a 1Duo will cover my other bike battery. Thanks again all, much appreciatedf!
Ok. Our post office is closed so ill av to take it to be weighed at th other one when im passing... Just been in hospital so dont feel like walking to far, so bare with... For a few days. Ps, How do you PM on here.
Scroll up to the top and next to the Triumph logo is an envelope, click on that, then choose the "Start a new conversation" option. Then in the Participants box start typing the person's user name you want to message.
I bought one of these when I bought my Ducati. After some 20 odd years it appeared to give up the ghost as the power LED didn’t light up so I bought myself an Optimate 4 to replace it. it turns out that it was just the LED that had failed and it still works so if that happens test the output with a multimeter before you splash the cash on a new one.
