Hi Guys

I picked up this Power Pack 'Thingy' in a Charity/Thrift Shop Today for just Two Pounds!

It looks like it was used to power a 12v Radio or some sort of Audio Equipment

So I was wondering if I could use it as a Battery Charger?

Any ideas

 

OB,

Yes, you probably could use that as a battery charger. But I wouldn't....

For a car battery, you really want to use a better conditioner, which will typically charge up to a certain voltage level, not let it overcharge, float it a certain level, let it drop then top up etc etc. I run conditioners permanently on all my cars and bikes. The previous generation of battery chargers which just tend to run quite primitive levels of charge and don't really have any intelligence to monitor the state of the battery, can be quite dangerous and will potentially boil a battery if left unattended.

Take it to the next car boot sale and dispose of it at a profit!

Hi Paul (ptjs)

Good Point!

But one of the things that I had it in mind for, was 'Kick Starting' some rechargeable Drill Batteries that I haven't been able to Charge in their Normal Battery Charger because they are Flat as Pancakes and I don't think you can Charge a Battery that doesn't have some Charge in it? (You would know, where I could only Guess!)

I bought these Batteries Years ago for £1 each! when a well known DIY Store had a Sale! and as luck would have it I got one of these Charging and this Drill has been Amazing ever since and would be even better if I could get the others Charged up, so I could have some to Swap over

 

Hi OB,

I agree that a short burst of a high amperage can sometimes throw some voltage into a failed battery where a normal charger doesn't want to start the cycle. Just check that your drill batteries are of a type that's about 9v+ before you use something that powerful. Also only use it for a very short period of time to do the kickstart before you then switch over to the proper charger for them.

Cheers

Hi Paul (ptjs)

These are 20 Volt Batteries and they are all Brand New! but so far have been un-chargeable because there is noting in them and when I put them in their Charger which also cost only £1.00 the Red charging light only comes on for just a few Seconds

Although the one that takes a Charge from the very same batch takes a couple of Hours to Charge but then seems to go on for ever until it runs down, which as always is in the middle of whatever you are doing

I'm hanging on to the Power Unit as a similar one on Amazon is about £20 and could be ideal for Powering a Stove Fan

 

well it says right on it to be used with a 240v supply.

if you want a car charger go with norco products. Very good products.

Fortunately 240v is what we have over here!

I use CTEK chargers and Noco Boost packs. Good pieces of kit.
