Hi
Car running dynamo at the mo. I have to top up the battery charge every couple of weeks in winter.
My charger has failed.
Is it best to buy a charger with lower trickle/overnight, type, for more frequent use please?.

Cheers, Dave

Buy a solar powered trickle charger for overnight use.  :X

Actually to hell with the purists. Fit an alternator.

That would be plain silly :-/ You would need a solar powered torch to find it :o

Agree with the alternator suggestion.

Lidl occasionally sell cheap smart chargers which work well.

Joking apart :) I have used the c-tech charger which is brilliant, and it comes with a kit to just plug in as well as croc clips :)

I have 3 trickle chargers complete with alligator clips . They stay on my cars when not being used. I'm looking for a fitting so that I can plug the charger into a cigarette lighter socket. There's a socket close to the battery on my 525i .

Hi Dave,
      it appears you use your car in the Winter; I would go for a quality charger that gives a decent charge rate as and when required.

Lead acid batteries like to work - a good discharge and charge helps to keep the inside clean.
Little use and trickle charge will eventually kill it.

I have a Halfords charger that is not too expensive and use to the boost my TR4 battery prior to over wintering (still be rebuilt).
I also have an old spare battery for 12V tasks in the garage that gets a boost every six months or so with a decent discharge prior to charging.

Are you sure the charging system is in good order? I used to use my Herald - still on a dynamo - regularly all year round and never had battery problems in winter apart from the usual finite life of lead/acid batteries after a few years. The one time it did struggle (in summer, by chance) it was down to a stuck brush in the dynamo, easily sorted.

If intent on running dynamo - add a 15-0-15 ammeter  to check load at anytime since 22 amps is not much and you can see which way the wind blows.
Always used one on various old heaps back in the day for reassurance ..

This is a timely thread for me as I need to replace my battery charger and I've just ordered a new battery for the Dolomite and I don't want to repeat the mistake of neglecting the battery.

Re batteries, my gaffer when i was an apprentice insisted i put an a couple of "asprin" in each cell :-/ .
I have always done this and have got to say i very rarely have to buy a new battery :) But i also keep them all well charged :) :)
Any scientific reason for this?? Others that do it say the same, also back in the 70's you could buy a product called "battaid".
Cheers,

Tony.

Tony,
You will also recall that gaffers loved to wind up apprentices, as do many people who post on message boards.

So much so that this myth is all over the Internet, usually in exactly the same form of words (not yours) as people are lazy and just copy it.

No battery specialist's site will endorse it (Dept. of No-Surprises), for isntance this (bottom of page under "Myths"): http://www.trojanbattery.com/tech-support/faq/

Ahh well, i dont know who told him? But he did spend a lot of money on asprin :) And he was a tight old bugger!!! He would look under his bed every morning to see if he had lost any sleep!!
I was also wise to wind up's, as my uncle warned me about them before i started.
Still, it's not done any harm to my batteries  ;)
Maybe the battery makers dont endorse it because it works? Who knows?
Cheers,

Tony.

Hi Roger,
Why do you think the above?
I have always believed that a deep discharge would "kill" a conventional battery & controlled float charge is beneficial for extended life?

I use a SMPSU unit to charge all my cells & batteries and would never use a conventional 50Hz transformer type as they are too expensive due to the price of copper Vs semiconductors.
A lot of the SMPSU's with microprocessors are overpriced though.

I use a imax charger b6 when i want to be anal and a Chinese (V-Cheap) conventional charger for ease of use.
Controlling the max charge voltage and current with a charger are also desirable and extend life IMHO. I charge to 14.7 volts for my 6 cell wet lead acid AKA car batteries @ room temperature.

I have a CCA measuring device ( electronic calculating type and not a true load tester).

Cheers,
Iain.

lidl have their cheap, but well reviewed, chargers in stock from today. Good value and should be very adequate for most charging (unless in a real hurry!)

Hi Iain,
             like a lot of folk one hears something way back and it sticks with you.  
The only technical basis for me to believe it is that Lead acid bats do grow chemical whiskers on the plates.
A high discharge and charge help to keep the plates clean.

Nice one Clive. I'll be going to my local Lidl after work (my good lady loves some of the £3.99 white wines that they sell) so I'll be keeping a look out.

I've had one of those Lidl battery conditioners for about 4 years.  It's always on when the cars parked in the garage and does the job well.

I've gone and bought one. I've got a brand new battery for the Dolomite but I'll be useful for when I need to charge it and it will work with the caravan battery as well.

I'd leave it on all the time when car is not being used. Not wait until the battery goes flat.  ;D

I bought one yesterday too - pleased to hear they are good! Now, how do I go about flattening the battery correctly that is currently sitting in my utility room?

Why would you want to?  Lead acid batteries do best when kept fully charged.

The cycling thing applies to NiCads and (to a much lesser extent) NiMH

Thanks Nick. Confusion is why, pleased I have the answer :-)

Here it is:

Has anybody heard of these type of chargers starting fires? There's been a couple of posts in my "resto" thread on the TDC forum about chargers starting fires. I've done a quick Google search and the worst that has happened is that the button stops working in a relatively short space of time. I thought that it would be the "conventional" chargers that are prone to this.

Dave, I think you need to ignore the wind-up merchants/misery guts over on the TDC forum. They clearly take every opportunity to "know better".

The TDC Forum?  http://www.androids.org.uk/forum/index.php?board=2.0

And a battery charger labelled "Ultimate Speed"?   What next?   a drinks holder branded "Hangover Special"?

Thanks John, that link is really great.

I need never visit my doctor nor A&E ever again!

John, I meant the Triumph Dolomite Club forum. I'm not bothered about the name on the charger as long as it does the job.

Sam, that's why I asked the question on here. As a moderator I didn't want to "fan the flames" over there. I've had to PM my fellow mod about the "fake news". I'm convinced that my smart charger will be fine. The only problem I've read about is the button failing in a relatively short space of time.

Its a cheap enough charger :) So who cares. It does the job........ So what if its got a silly name..... Its got to be called something ;D ;D

Well I was sold on it the moment I saw it had a Flirt processor. My analog technique hasn’t worked well for some time.
