batteries

[Bielie45]

I have a 5 year old Lithium Iron battery in my 14.
Alien Nation brand and as KiwiCol said by the sandards of Litium Iron batterys today mine is a dinasor but has not missed a beat even for the last 2 or more years I recon I only done 1200km and dont trickle charge at all, so very inpressed so far

AGM, seem to be the recod ones. bigger can of worms than which oil. so many diff. opinions, hard to know what is truth. i have a lithium phosphate jump pack, weighs same as a six pack of beer, puts out 1500cca, re charges in 40 seconds. i use it average 10 times a day, my job. it starts a v8 diesel landcruiser with ease. had a motobatt, just replaced it, useless. might as well just buy yuasa oem, they last but less than 200cca. does the job. hvt8 is my choice now, agm vrla batt. tests at 350cca. bike just zings over, quite amazing. lithium is much lighter, who would notice it? https://superstart.com.au/hvt-8-ultra-high-performance-agm-motorcycle-battery.html

@grog  These sound like a very good battery.  How do you assess the cca rating at 350? I'm assuming you've load tested it or something to determine that it's putting out 350, so I's like to know how to do that test.  I'd use it on other batteries as both bikes have new ones in them.
I can test my batteries using my carbon pile load tester, which shows if they stand up to the load or not, but it doesn't say 'this battery is producing  xxx amount of cca & has xx rc value'  I'd like to know how this is done, thought it was just applied by the manufacturer & sold as that spec, but there must be a way to test it too.

Col,
I use electrical meters which can read 100 plus amps while the starter motor is cranking, then using basic electrical calculations can determine if it electrical or mechanic problem, load and no load. As I mentioned in a previous post it could be anything, easy way to know is if your mate has a similar size battery with no starting problems borrow it, however a good/new battery will recover quickly from extra load but it will weaken if under pressure.

I have to say I never had any starting problems with my bike until it was about 8 years old then the clock reset problem started, new battery no problem. I think with battery you can be lucky regardless of type who really knows what is happening under different conditions, UK cold Australia Hot, but aren't they all built for those different country conditions

Not a bike battery but Lithium Ion, I bought 3 years ago in a Hitachi drill kit, was charged when I left UK 2 years six months ago I was reusing it with same charge 2 months ago and has been charged several times since and still going.

Agree Irish, all batteries a bit of luck required. Col, my Midtronics & DHC. Both work well. Have a google.

[KiwiCol]

Brought one of the DHC type. Not exact same as they're out of stock on those ones, but the one I got does the same stuff & can connect to laptop for printing if I want that - not really as it's just my stuff. 
I was counting up on the way home, just how many batteries I've got in things. 5 bikes, 3 cars & a boat with 4 batterys in it. That's a dozen 12v batterys! (plus a couple of spares in the garage, so 14 all up)  Might have to change my handle to batteryboy!

Plus the 5th wheeler, so 15 & counting!  + helping friends & family out.

You gotta lotta toys !

But no Landy Mike!  The Merc scoffs enough juice as it is,    Couldn't afford to run a proper 4wd as well.

[grog]

well done Col.Mr Toyman. to test your batteries, correct way. charge each one, let them sit 24 hrs or use your carbon pile bring volts down.  voltage around 12.6 to 12.9. away you go. higher voltage reduces cca, false reading. if volts are less, failed battery. simples. agm run slightly higher volts but only .2 or .3. lithium another story.

My K6 is still on original battery and dosn't seem to be loosing any of its power even after standing for months at a time with no trickle charge .

YUASSA!

Yuasa seems to be the brand of choice. Fairly sure Lord Barmy Esq  recommends them. 

That's what I got recently when I replaced my OEM battery.

Indeed he does! Never had an issue with Yuasa and they have great longevity. Will always be my battery of choice

Aye that's what I put in my 14 about 5-6years ago when the original one died.

As a battery changing tip though, don't walk over a mile to the shop to buy it as you fancy walking the dog too. They get quite heavy on the way back...
