Jump start should be avoided at all cost with late model cars.

You can however regularly charge the battery using smart charger to extend the battery life.

Is something like this charger ok for car batteries and 33AH SLA batteries. @jeffnz, any good for those batteries I got from you?

Usage: charge some 33AH SLA (AGM?) batteries I have, and extend the life of my my car battery. Unconcerned about charge time. 2A seems small...

@timmmay i use one of these: http://www.ctek.com/gb/en/chargers/MXS%205.0

got it from repco for a little over $100 but could probably be had cheaper when on sale.

It will work All types of 12V lead-acid batteries (WET, MF, Ca/Ca, AGM and GEL) 1.2Ah up to 110Ah batteries and also has a recondition function which for Lead Acid batteries can help revitalize them.

I use the recondition mode once a year on the car batteries

Thanks Jase. I know I could spend $100 on a charger, but to help increase car battery life and to top up SLA batteries it doesn't seem worthwhile. Would that $20 charger be worth getting, given it's a 3 stage smart charger, or is it not worth the bother?

Don't bother with the cheap one. I got one from the warehouse (autohaus) brand. It is a smart charger but not temperature compensated etc. The battery get quite hot and starts to produce condensation around the cap.

I returned that charger and end up getting a ctek smart charger. It works like a charm. I left on the car for 3 weeks - no problem. I bought the comfort indicator which permanently hooked to the battery with port outside the car for easy charging.

Considering the trademe one has a chinese plug on it, it isnt actually legit to sell it.

Ah ok. I was hoping for a cheap simple charge for the 33AH SLA batteries I got from @jeffnz, since moving them inside to charge on my DC UPS is a pain in the wrist. It's not worth $150 or more to me, $50 max.

@richms The trademe charger has an NZ plug on it, according to the text and the pictures.

The picture clearly shows a chinese plug, top exit when used in a NZ outlet and non insulated pins. Depending on the age of the specs used for it the pins may be thinner and longer than a NZ one so it arcs and stuff in the socket.

Ah interesting, I didn't know the Chinese used a plug like that. It says NZ plug in the listing.

Thats because people assume that if it fits its ok.

Actual plugs for AU/NZ will have an approval number molded into them and for side exit ones will leave at the 4:30 position, not straight up - as chinese sockets are mounted the other way up. There is also the issue of the supply cable as anything sold here has to have at least a 0.75mm^2 cable, and in china its anything goes so will often be half or quarter mm^2 cables.

Trademe dont care when you report things like that.

I bet the seller also cannot provide a SDOC for the charger when requested, which any appliance importer must be able to do on request.
