Battery question

Not compatible with stock cables..it's a battery change ..and was looking for a few options that work year round as I ride for a chapter of BACA and we ride on a moment notice day and night, 12 months a year in cold climates

Annndddd still looking for suggestions for a cold weather battery. Thread seems have been highjacked in three diections. Actually lots of great info but still looking for some basic recommendations

Not sure what your running I used to be picky but long about 2009 I added a second battery to my system and otger then replacing the main battery a couple times the extra 600 amp 20 cell lithium ferous Speed Cell is still kicking. I'm not sure what your doing with your air box but I store tge extra battery there with some tools my PCV and the drain control valve on my baffled oil catch can.

Anyway 920 cca turns over like a mad man. Feels like you can do a burn out with the starter. In fact still have the 1.4kw starter to install. Had it for 3 years now just haven't been to pressed to put it in.

Tis totally compatible with stock cables - and even 2 sets, which I have done for improved starting.

My error and thanks. Your running tandem?

Never had a problem with the batteries that wallyworld sells but then again I replace my battery no later then every four years usually sooner , I do not wait for the battery to give out.

I do wish I had your scenario!
My batteries $hit the bed every two to three years, regardless.

Yes indeed. I opted for a second set of OEM cables from Ebay in order to improve the cranking.

Well leave them to sleep on the floor!.

Scott - I have discovered that keeping them connected like that ALL THE TIME - actually can damage the lead acid one.

@patrol21 One issue I discovered early on - when I was making my own LiFePO4 batteries - is that Lithium's will try to maintain VOLTAGE as they discharge at the expense of AMPS. Lead ACID will tend to maintain AMPS at the EXPENSE of VOLTAGE. On old vehicles this was not an issue - but ECU's are fussy about Voltage. If it drops below 9V whilst cranking it does not matter haw many amps you have. I made an 1120CCA Lithium to prove the point.

I have experimented at having 2 batteries (one to feed the starter and another to feed the rest) - This works very very well indeed.
BUT I had problems keeping them charged correctly. I used a split charging box but somewhere in my logic I was creating a huge surge and kept blowing fuses.
Split charge systems need both batteries to be the same type for a start.

MY ADVICE STANDS. Have a good Lead Acid in. Add a Q/D cable connector and keep a small lithium booster in your jacket (keep it warm). Plug it in to start . Disconnect once started. Recharge teh booster once you stop to keep it 100%.

I'm not sure my regular natteries life soan was dhortened or not. The last one the bike had was great then I took it to carpenter's for what was suppose to be a month and well 9 monthd later they called and said the battery was shot. Mind you I pulled the speed cell and thru it up on the shelf so it went yo the shop with just a 320 good scorpion battery. Anyway if it is shortening the life span its not enough for me to notice. In fact the last battery's life span was the shortest but well but it was also the first time I did not have the bike to start up and run during the winter months.

Hi guys can anyone recommend a good starter battery and how long do you expect one to last ? Mine stays on a trickle charger but still fails to crank when really cold . Cheers
