Rechargeable battery advice

2200mAh are the latest and greatest but my problem now is with the run time of my CP5000. Thomas Distributing

Has anyone tried the GP 3500mAh c cell batteries?

Seems a very high rating. Would such a high rating effect how the re-cycle time in a strobe?

I have a set I used to use in my Ike AI strobes. 3500 mAh for a C cell is not high. They range from 3000-5000mAh. The larger the battery the more capacity (mAh) it will hold. Again, this is not voltage it is capacity (run time). For example, D cells range from 4000-11000mAh. As for recycle time, I'm not sure if the quality of the battery has anything to do with this but the higher mAh rating will not.

Has anyone tried the Uniross 2300ah AA's with the 2hr sprint charger. Costs around £27 here

 

Cheers

Hi all,

 

any one up on the skinny about the differences between lightweight rechargers, such as the ipowerus FC402 (110/240V) and the much (4x?) heavier chargers, often requiriing an ac adapter and often single input voltage?

FYI, there is another thread (locked now) in the slr forum:

I'm replacing all my AA's (24) for an upcoming trip. There once was a link to a comparison chart of the different brands and their performance. I haven't been able to find it. My 1st thought is either Maha's or Ansmann's from Thomas Dist.

 

Also, has anyone tried the newer 2500+ mAh batteries? My old ones were 1800's.

I can see how higher mAh batteries would off gas more. I'm wondering if you wait a day after charging before putting them in the strobe if that helps things. I think the newer strobes can handle it, however the older ones don't, so they advise against the NiMh. I once had a strobe flood and I recall that the batteries were still warm when I put them in before hand. I see there are now 2700 AA's available, and I was wondering how much extra risk is involved?? Thanks- John

I have used 2.7 Ah NiMH in my Inon Z-240s (type II) and Nikon SB800 strobes for several years now without incident.

I too use 2700 mAh batteries in my Inon Z-240s (type 1 & 2) for the last few years without any problems and I change batteries after two dives to a fresh set. I also use a pulse tester to check my batteries before each trip to ensure 100% capacity.

I have been using these PowerEx http://www.mahaenergy.com/store/item.asp?idproduct=352 chargers and 2700mAh batteries http://www.mahaenergy.com/store/viewitem.asp?idproduct=415 with my Sea and Sea strobes for the past two years. Have been performing flawlessly. Lightweight and very easy to travel with.

We are so on the same page Elmer.

It is funny how these NiMH batteries lose their capacity after sitting around for a few months. With the pulse tester I am assured of a good set of batteries for the trip.

pulse tester? as opposed to a volt meter?

ULCS offers this Pulse Load Battery Tester. I've found it to be very helpful in determining bad or low capacity cells. It's listed under "What's New" at the bottom of their web page.

 

Advantage of Pulse Load Technology

Battery performance is very important in todayÕs electronic

devices. The Mini-MBT computes the batteryÕs

actual remaining power capacity using a 2-second pulse

load test. This pulse load simulates the real power

demand that batteries experience during normal operation.

So battery performance is measured, not just

voltage or internal resistance. The load is automatically

disconnected, so testing will not harm or drain

the battery.

Testing capability: 1.2v NiMH rechargeable [AA, AAA, C, D]

1.2v NiCd rechargeable [AA, AAA, C, D]

1.5v alkaline [AA, AAA, C, D, N]

3v photo lithium [CR123, CR2, CRV3]

9v alkaline, carbon zinc

Display: Five (5) LEDs - Green, yellow, and red

Contact terminals: Nickel-plated brass. Positive terminals fixed. Built-in

negative test lead.

Dimensions: 4 x 2.5 x 0.75 in.

Weight: approx. 3 oz. (85g)

Part No.: Mini-MBT
