I will not be using my Hytron 50's for a little more than a month.
Is it best to keep them on charge for the month or not?

In general is it best to keep Batteries cooking?

Regards,
Adam Keith

I recall reading the Anton/Bauer manual that said its preferable yes. Unless anyone can think of a reason not to, I'd do it.

charge them up and then charge them again after the month, just don't let them get below 20% if they are Lithium. I wouldn't let them cook for a month straight, mainly due to fire hazard, if a cell goes bad.

Gents--

I leave all my A/B products on their chargers when shooting and when resting at home. All the time. Never had a problem.

Remember, their chargers talk to the batteries so if there were a problem, the charger would stop the trickle process.

If you have serious technical concerns, why not send an email over to Paul Dudeck and let him set the record straight.

Any battery will last longer when maintained at a high state of charge rather than slowly self discharging.

Just a quick note on Lithium batteries.
It's not good to keep a lithium battery at full charge, so best not to keep them on the charger. PAG chargers from what I have been told will not continue to top up lithiums if kept on the charger anyway.
If you are not using your lithium batteries then keep them at about 40% although they will slowly discharge over time.

I'd love to hear Paul D. weigh in on this, in light of Richard's suggestion. Looking forward to eking out a nice long life from those HC's when they show up!

My info come from having a long conversation with one PAGs head engineers while he was doing a software upgrade on my set of new L95's That's right, a SOFTWARE upgrade on a battery. There is even a "hidden" menu system which will give you an exact percentage battery life, and will also tell you how many cycles your batteries have had.
They also have a new high current battery coming out soon too...

Rick.

I've been told 40% too. Other chemistries require different treatment though. I know lead acid sods up if it is left fully discharged.

From what I understand Lithium bats degrade at a relatively constant rate, regardless of cycles.

Just be careful to keep them from discharging too far. If Lithium ion batteries discharge too far there usually isn't any coming back.

I did say IF they were... but there is some great dialog about lithium care too. Sorry about the thread jackin' Adam

I emailed Paul Dudeck from Anton Bauer.
Here is his reply:


Hi Adam,

Always keep your batteries on a charger unless you are going to go thru
long periods, like more than 3-4 months without using them.

Paul

Well like I said, PAG chargers will not top up lithium batteries when on the charger, so you can keep them on the charger, or gaffer tape them to your face, glue them to the ceiling etc... Won't make a difference... Don’t keep them fully charged tho…

I recall when I had a stack of ProPacs, Hytrons and a couple of TrimPacs, and the documentation for all of these stated, as Paul says, to leave on the charger when not in use, except when they are going to remain unused for a long period of time, in which case you should put them through a discharge cycle and store them empty.

Must be an issue that's perculiar only to Anton/Bauer.

It is definitely never good practice to store batteries in their case fully charged...I always try and run them down and then charge them before each time I go out. Not always possible, but works most of the time.
