governorsam Posted July 11, 2021 Share Posted July 11, 2021 Best time of year for battery sales. winter kills them. used to work in that trade. Quote Link to comment Share on other sites More sharing options...
Kimjon Posted July 24, 2021 Author Share Posted July 24, 2021 ***Update: Swapped out battery, with a known good one from a mates tractor. Took it for a drive, pretty much same as last time...all good for 10 minutes, then no charge going on. So Swapped out alternator...problem gone. so it was the alternator that caused all my issues, just as I suspected. Cheers Mike - fucking legend for giving me an alternator for free!! 8 Quote Link to comment Share on other sites More sharing options...
Stu Posted July 26, 2021 Share Posted July 26, 2021 Nice result! Can you link to the bluetooth battery monitor you use? Quote Link to comment Share on other sites More sharing options...

I paid $30 from ebay delivered. They normally take about 2-3 weeks to turn up. https://m.aliexpress.com/item/1005002038313820.html?albpd=en1005002038313820&acnt=494-037-6276&aff_platform=aaf&albpg=296904914040&netw=u&albcp=9444695485&sk=UneMJZVf&trgt=296904914040&terminal_id=01e04a3f896441319a8986b0c5d6e427&tmLog=new_Detail&needSmbHouyi=false&albbt=Google_7_shopping&_randl_currency=NZD&src=google&crea=en1005002038313820&_randl_shipto=NZ&aff_fcid=04dad6e041704aba9f52cc6d0d29e53b-1627360659756-04126-UneMJZVf&gclid=CjwKCAjwuvmHBhAxEiwAWAYj-PXmE_GE2ZlcgYNEUDXD9A-OJJLCMcLHfeL8GtrN9JAu7apK4HZF8hoCxsQQAvD_BwE&albag=99457316601&aff_fsk=UneMJZVf&albch=shopping&albagn=888888&isSmbAutoCall=false&aff_trace_key=04dad6e041704aba9f52cc6d0d29e53b-1627360659756-04126-UneMJZVf&device=m&gclsrc=aw.ds Quote Link to comment Share on other sites More sharing options...

Kimjon Posted July 28, 2021 Author Share Posted July 28, 2021 My battery is also well fuckered. @flyingbrick tested it for me and if it was an animal animal you'd be giving it one in the back of the head and down the offal hole... But im glad I have solid answers now. 1 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted July 28, 2021 Share Posted July 28, 2021 I find battery tech quite interesting for a multitude of reasons. We all have this physical item made out of basic and identifiable materials which is expensive to purchase and costly (to the planet) to recycle- yet repair is largely out of the question. It shouldn't be because a lead acid battery is incredibly basic! @Kimjons battery bugs me. I can charge it to over 14v (Using bluetooth battery monitor to log voltages is amazing) but then the instant you apply any load it drops to below 12v. The float/indicator is red even at full charge which could simply mean that one or more cells is low on electrolyte- but the battery has a firmly glued down cover which does a pretty good job of preventing any level checks or top ups (without making it look like its been butchered) TLDR: battery companies go out of their way to ensure these things aren't serviceable. Bastards. With that said, have had a few good wins with the desulphater (Validated by load testing down to 12.2v and measuring capacity). 3 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted July 29, 2021 Share Posted July 29, 2021 Car batteries are super recyclable, one of the most effectively recycled items in the world. That's why they are still allowed to be made of lead. Unlike circuit boards, they end up getting burnt in Kenya Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted July 29, 2021 Share Posted July 29, 2021 @NickJ that is a brilliant idea! Do the cells all join at the top? EG if I fill up one will it top up the rest? Also, worth shaking it up first and checking the specific gravity of the electrolyte? (I think thats a thing?) IF you know more about this than you are letting on, you should definitely share Quote Link to comment Share on other sites More sharing options...
GuyWithAviators Posted July 30, 2021 Share Posted July 30, 2021 Pretty sure I read a yarn on here where someone just cut holes in the top of each cell bank, topped them up and glued the plastic back on. @Ghostchipsor @SOHCmaybe Quote Link to comment Share on other sites More sharing options...

UTERUS Posted July 30, 2021 Share Posted July 30, 2021 I've had some success with a desulphator and charger on a battery for a few weeks. https://a.aliexpress.com/_mNukyZN Quote Link to comment Share on other sites More sharing options...
Testament Posted July 30, 2021 Share Posted July 30, 2021 Dropping them flat on the ground to rattle some the sulphur? off the plates just as hard as you can without busting the plastic case and spilling battery acid everywhere (who would guess that could happen) then putting them on a battery charger with pulse/maintenance mode/one of those^ things sometimes works 1 Quote Link to comment Share on other sites More sharing options...

IF you know more about this than you are letting on, you should definitely share So as it was told to me, the cells share a common air path at the top but not electrolyte, having a few dead batteries in the shed I gave it a go, can confirm the battery I pulled the level plug from does not have a common air space, only poured a few ml of acid out, scratch that idea 1 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted August 1, 2021 Share Posted August 1, 2021 I am still playing with @Kimjons battery. The Bluetooth battery monitor logging is brilliant. I thought my desulphation charger thing only had a set voltage but turns out it alternates up and down for some reason. It is getting better, managed to actually run a discharge cycle on it yesterday. 1 Quote Link to comment Share on other sites More sharing options...

I topped it up with distilled water- but yeah didnt really seem like it was filling the other cells at the same time. I think I'll try harder to get the cover off.
