Using NiMH rechargeable batts in torches

I hope your Vapextech batteries are better than the ones I got. They said 2900MAh on them but I'd say they were more like 1000MAh if that.

Don't worry though, I could have just got duff cells as other people seem to like them.



Terrible batteries - you'll be lucky to get more than 2200mah out of them and they';; self discharge in a week.

Eneloops or some form of LSD NIMH is the only way to go for rechargeable batteries.

Well, I won't be buying Vapextech again. I used four batteries out of the eight I bought and put them into a small lamp with a sensor that turns the lamp on when someone is near. They lasted much longer than my previous batteries. But when I went to charge them in my Uniross 15 minute charger, only two of them charged fully and the other two appear to be dead already. None of the four lights flash on the charger (which is indication of each battery charging) regardless which charging slots I put those two batteries in, and this is the first time I've tried to recharge them. I questioned my charger which is quite old now, but I think it's still working ok as other batteries seem to charge fine. I'll buy some Eneloops.
 
My 3 quad sets of Vapex 2900 are just fine. I don't use them in a torch though but 3x camera flashguns which require fast recycle times and heavy usage.

I also have 2 hotswap Vapex on my G700 mouse and they work as good as the Eneloop battery that came with the mouse.

Well it seems my Vapex are still all good. I switched on the charger again today with those 2 batteries still inserted, the lights flashed, and the batteries charged up. :) This happened to some other batteries of mine, when they wouldn't charge and a day or so later they charged. It must be something to do with the charger.
 
I have the Uniross 15min charger too and sometimes it will sit there not registering batteries yet the Sony charger next to it will charge those same batteries.

Rapid chargers can be finicky.

Ah, interesting. Perhaps that's what's happening to mine. Mine is the sprint 15. This one. Is it the same as yours? Mine's pretty old now.

Is your sony a rapid charger too?
 
Yes!

I bought it about 5 years ago. Maybe longer actually. Was £40 and served its purpose as a quick charger for my then flashguns!

The Sony one is not a rapid charger no, it charges in a couple of hours but I only charge while present so it's no issue really.

Ah, well mine must be around 5 years old as well. Perhaps they start wearing out and not registering batteries properly?
 
It could be, I don't use it as often any more so when I do it does charge them first time.

Throw that charger in the bin.

That Uniross 15 minute charger is killing your rechargeable batteries. Using that charger will drastically cut the number of cycles you can obtain from your batteries.

My old workplace bought one years ago and I told them to throw it away. Within 15 minutes it heats the batteries up to a ridiculous high temperature, so high that you cannot hold the battery in your hand (!).

It pumps something like 6A into each battery :eek:. You should be looking at around 1A for maximum number of cycles. It will take a couple of hours to reach full charge but it's safer and will prolong the life of your batteries.

Thanks, I'll get a 2 hour one then. Can you recommend me one?
 
As stated you only really wanna use LSD batteries and I strongly recommend the latest revision of Sanyo Eneloops :-)

Also as a above you need a decent delta-v charger that use's single charge circuits or you will kill your good cells pretty quickly with rubbish dumb timer ones.

Out of stock at the moment and it's gone up slightly but definitely worth a tenner: 7dayshop 808LCD

:)

+1 for this charger

Plus unless your in a hurry for your cells use the current limited USB supply option (recycle an old 500-800mA 5V transformer) and charge over-night, this will effectively trickle charge the cells which is far better and will prolong the life of the cells significantly!
 
Thanks guys. I think I'll keep an eye on the 7dayshop 808LCD since it's only £9.99 when in stock. That Ansmann Energy 8 is around £52 and upwards.

A few months ago I bought the "Energizer Universal Battery Charger" and it seems to be good, haven't used it much tho yet

Charges AA, AAA, C, D and 9V rechargeable batteries. 3-5 hours charging time (AAA 1000mAh to AA 2650mAh). LCD panel indicating charging status: AA, AAA, C, D and 9V charging; bad (primary cell or fully rechargeable) and 'full' LED indicator.
