Battery & Trickle Charger
 

Due to being cheap I decided to purchase a trickle charger from Aldi, which seemed to be doing a good job until yesterday when I found its now buggered.

The consequence of which is the battery is now buggered and won’t charge.

So I need a new battery and trickle charger and was wondering if anyone had any recommendations other than what I am thinking below:

Genuine battery from Cox as there’s a sale on and purchase a Optimate trickle charger (I used to have one for a bike engined kit car)

Comments/ thoughts greatly appreciated.

Cox/Hendy for the battery

Optimate or ctek for the charger. Loads of threads on those if you have a search.

Been using a ctek for years

Buy cheap, buy twice it seems. A ctek may revive your battery

Depending on the state of the battery most chargers need to sense a voltage before they'll start charging - so if the battery is totally flat it can be resolved by giving it a jump with another 12v battery to kick the charging off. - having said that the button stopped working on my Lidl "Ultimate Speed" charger.

To recover a dead battery you really need a very low amp "dumb" charger and trickle over a couple of weeks, although my Ctek seems to do a pretty decent job despite it not being the "proper" way of de-sulphating

I had a similar situation, looked like the Lidl charger was fubar, stuck it accoss a good battery for a few hours and then accoss the dead battery, it then burst into life charging a dead battery.

I've had a Ctek MXS 5.0 for a while, can't fault it, it also has a battery reconditioning function that can revive and save some dead batteries too.


Also works with AGM and lead acid batteries, so pretty versatile.

I have 3 CTEK charger on the go at the moment for all 3 of my cars which all rarely get used, haven't had any problems with them.

Another CTEK user here :) gets my recommendation!

Yep, CTEK here too :thumbup:

I have had a CTEK for many years. It has seen a lot of use. I used it at our dealership as there were always vehicles sitting unused for long periods of time, often in cold weather. I took it with me when we sold the shop and maintain some of our vehicles that see limited use, like the S2000. I find it hard to believe that it still works great after all these years. I also have a Battery Tender, and had the included harness hard wired in the NSX. It has also been bulletproof for the last 6+ years.

Optimate 6, fit and forget. It has also recovered batteries that wouldn't charge on another charger.

I bought a new battery from Honda last week as mine died over the weekend and it wouldn't charge when left over night.

Im buying a ctek

buy a c tek they are brill do not scrip on your nice car

ya ctek

have one running for 5 yrs now,no issues

This is all very true.

The only issue I had with one was when I drove off having forgotten to disconnect it.

I'd be useless with a BEV...

I haven't managed to do this with a trickle charger yet, but did forget about the block heater cord a couple of times.

I got two CTEK chargers, one is over 10 years old now and still works great, Swedish quality :tipwink:

How much for the battery from Honda?

I paid £50 ex vat from Cox

Good price - I just paid £78 for one for the 86.

Similarly, it's a small battery and thus not long-lived.

For anyone with a ctek charger does the 12v in car connector work as a way keeping the battery charged up, as opposed to connecting to the battery terminals under the bonnet?

Thanks

Don't think that will work. Did it come with the plug that can be wired in?

I’ve not bought one yet, I just noticed their was an option for the cigar lighter but needed a permanent live and wondered if this would work for the s2k.

The 12V outlet in the car powers off with the ignition so not going to work. Just connect it to the battery instead.
I got mine poking out from under the hood for easy access, I use the blinky led version which tells you the battery state of charge.

Since it's a switched, not a permanent live, no.

Just get the pluggy-in thing to stop you having to twist off the red cover off the +ve terminal all the time. Only trouble is, the bung in the end falls out after a while, so it's not really sensible to leave it exposed in the wiper area.

Battery on or off to recharge.

In this recent cold weather anything more than 8 days without running it results in a sluggish turnover. Tried to start today after 10 days and not much more than a groan and clicks.

I've jump started it before but just want to give it a decent charge...

nice.

Is Cox a sponsor on here?

They offer a discount with S2KUK membership but it's only about 2.5% or something. Usually covers the postage.
