Lithium Ion batteries and Pard NV007

[PaulCat]

Like many people I use UltraFire-type batteries in various pieces of equipment. These range from 4800mAh to 9800mAh but being bought online may or may not be the real deal, I've no equipment to test them.

Either way my Pard NV007 chews through them like a vibrator in a convent. I also find that spare batteries lose their charge over a period of a few weeks and I get through (say) four batteries in a five hour session (and that's with me switching the unit off between scoping sweeps and shots). So I have two questions, one for NV007 users and one general:

How long does a 4800/9800mAh battery last in your unit? More often than not I put in a fresh-out-of-the-charger battery and see only two bars on the battery indicator, is this normal?

Is it safe to leave Lithium Ion batteries on permanent charge so that they are topped off each time I need them?

I'm thinking a good quality (ie, not the £2 charger from eBay) 'intelligent' charger like this one might be what I need.
Intelligent charger.



PS. I'll be asking on Nightvisionforum too so apologies for the repetition if anyone reads there as well.

Avoid anything with 'Fire' in the name like the plague! Get decent ones from a known retailer such as Torchy etc.

Those are also false claims regarding mAh for the 18650 battery - my Panasonics hold charge and will last a few outings with the Pard 007 (on standby between shots) between charges.

Is the charger you've linked to genuine Nitecore unit? These are.

Spot on.

I use genuine Samsung 3000mah and they have always lasted any 3 hour dark trip ive done without a change.

Also use them in my ecig and they last all day.

Thanks for the swift responses.

I can't recall where the chargers came from. Possibly with a device although at least one was lost and replaced from 'Snap Off Tools' in old Gangzhou.

"Fire......crap.......avoid like the plague....". Noted.


Edit to add: I can tell Orion didn't click on my link, he's linked to the same unit!

I did, but there are some snide Nitecore units doing the rounds.

The 7 Day Shop chargers are known to be genuine and for a couple of quid more the Nitecore D4 charger would be a better unit.

Bloody hell, is there anything these days that hasn't been copied?

Righto. I'm off to shop for real ones. Thanks all for the info.
