Sodium Ion batteries

(1/4) > >>

Orcade-Ian:
The battery on our 5 KVA standby generator has never been brilliant and needed charging every month or so.  As a temporary measure I fitted the Motobatt from my 400/4 - a noticeable improvement in speed of starting - it's a Honda GX 270 single engine.  Looking for a replacement - I was quoted £110 plus post and vat.  A friend showed me an article in a bike mag from a company called 'Biker's Toolbox' who had a Sodium Ion battery on test on a big BMW and were very impressed with its performance.  Difficult to believe that it's only a 3AH rating BUT has 300 cold cranking amps as opposed to the original BMW one of 200 CCA.

I ordered one (£51 inc del to Orkney) and it arrived today.  I can't believe how little it weighs!  Under 1Kg.  Fitted to the Genny it flings the thing over faster than the original battery ever did, or  the almost new, fully charged Motobatt.

It would easily fit the 350/400 and 550 fours I have and has dual terminals.

I'll see how things go but apparently they do not suffer the problems associated with lead acid batteries - time will tell but worth a gamble to me!

That’s great news on the battery front Ian! Interesting to see how it lasts, and unbelievable CCA’s too. Not needing a battery at the moment but will consider ad and when.

I am a mobatt convert , I had an issue with my Triumph 1050 sport every time I stopped and the engine was hot it wouldn’t start until it had cooled down and various posts mentioned changing cabling from battery to starter motor and I also stripped  down the starter motor and changing the earthing but the thing that fixed the issue was changing to a Mobatt battery.
With the slightly higher current output it cured my issue for good.
I have subsequently also fitted one to my 400 4 but will be interested to see how you get on with this new battery.
The Mobatt is more expensive but I was spending a fortune on coffees waiting for my bike to cool down

Orcade-Ian:
Ken,
I can't believe just how good this battery appears to be!  True, at 3AH its not going to be any good if you leave all the lights on with the engine stopped but not many folk do that anyway.  300 CCA can only be drawn for a very short period (on paper 1/100th of an hour but less in practice). How long do we normally hold the starter button for?
As I say, very light in weight and no lead or cadmium - only sea-water as electrolyte.  They will never compete with Lithium Ion batteries for EVs for charge density but seem fine for our usage.
I'll keep it on the Genny for a while (nothing to draw current when off) and then swap to one of the bikes - probably my 550 if all is well.  Seems just too good to be true - bound to have an unforseen drawback but I like testing emerging tech.

Depends how critical the charging current and voltage is, our old style regulators are not good enough for li on so definately not sure about the sodium
