Lithium batteries are really great, they have a higher voltage(doesn’t drop much under load to), more cranking amps and way more lighter witch is good for any sport bike. You just have to be careful if ever need to charge it. If I wouldn’t be in a cold weather country it’ll be the replacement when ever the OEM is gone.Yuasa batteries have always served me well too. Had a WPS lithium battery in my Stand up jet ski (salt water surf only) for 5 years, never once charged it and it was still working when I sold the ski. Was always impressed by that battery.
Looking at a lithium replacement myself, I ride through winter so it’s probably not the best idea, but seldom out below freezing and would like to give it a go.In general you simply cannot beat YUASA. I am big fan of LiFePO4 - but they have some issues if it is cool outside - and the usually "warm up" tricks are going to be an issue with a 790.
I have used Motobatt AGM often. I will investigate their LI.Any recommendations? The Shido’s seem to have been discontinued. Been looking at Exide, Motobatt and quite like the look of ReLion (although not the price).
Do you have a link to a compatible one that you can actually buy online?If you want a GOOD and I do mean very good LiFePO4 battery - the best I know of are I-tecc in Germany. They use A123 cells and this gives them a VERY high discharge rate. I have used A123 in the past to make my own 1120CCA monsters. Expensive? - Yes!.
The Terminal orientation I would say IS IMPORTANT on a 790/890D - The cables are short.Does anyone know how important the side the terminals are on? My bike has the negative on the left from memory and the batteries I seem to see recommend for the 790 Duke have the positive on the left. Are the cables long enough that this is not an issue? This is the battery I'm thinking of YTX9-BS Lithium Motorcycle Battery - Save 2.3kg over stock!
...And $100 for a Duke compatible battery looks very competitive.I am interested to know if anybody has tried the NOCO LiFePO4 batteries. I am impressed by their chargers and also their booster packs. What's more - (yes I know, I know) they look a damn sight better (prettier) than most.
Motobatt seem to be very LOVE THEM or HATE THEM. I have one (NOT A LITHIUM) in my Guzzi and it's been fine. Came with 2 year warranty.I looked int hybrids Motobatt MH14B4 Hybrid Lithium Battery
Sounds great but has bad reviews In Australia and only 12 month warranty
