NiMH:s, 2500 mAh vs 2700 mAh? chargers, brands?

Recommended Posts

Getting new NiMH:s for Inon Z240:s and wonder if anyone have used both 2500:s and 2700:s and could share their experience? Any noticable difference in recharge-time of the strobe? Antyhing else?

 

Also read the thread about the 'thick'-bodied batteries that won't go into the battery compartment of the INON strobe properly. Is there any particular brands to avoid or any specific to reccomend?

 

Finally. Anyone who has a nimble (for travelling) fast charger that they are happy with and would reccomend?

 

cheers

My "battery gal" told me when I was looking at replacing my 2100s that the 2700s were not as good as the 2500s. She said she'd seen more failures on the 2700s than the 2300 and 2500s. I've used the Panasonic 2300 & 2500 for travel and in the house for the last year. They've been recharged at least 150 times for various strobe and other uses. My Eveready 2500 are losing charge faster and they are newer.

I like the panasonic AA/AAA slim travel charger and I usually carry 2. You will need a plug adaptor since they use dual flat pins. They take a good beating.

I've used the 2300 Mahas and Ansmans, 2500 Mahas and 2700 Sanyos and Mahas.

 

I don't really notice any difference in recycle time in my D2000Ws, but then my prev camera was way slower than the strobes.

 

The only batteries I've had problems with are the 2700 Mahas, and to a lesser extent the 2700 Sanyos. I treated them the very same as the others and the 2700s are volatile (i.e., sometimes they just don't fire).

 

I use the Ansman charger for 6 batteries, nice small plug that doesn't hog the power strip (Ryan at ReefPhoto suggested that one to me and he was right), and I use a La Crosse charger for 4 batteries for backup that I like less than the Ansman. If I had it to do over again I'd get two of the Ansman, they aren't very big and they are quite lite and bulletproof.

 

Just my experience,

I've had problems with the Sanyos and have heard others that have also. Thomas Distributing is a good place to buy everything.

I've had very good luck with Mahas - they have good charge cycles that seem to be battery friendly.

So far I've had very good results with the Maha 2700s. I also reccomend a very good charger, I have the Maha MH-C800S which has independent circuits ( like the Ansman) and has a conditioning mode which I use every 10 charges or so.

 

Take care,

John

I use the Ansmann Digispeed 4, which will charge 4 x 2700mAh NiMH in just over an hour. It has a cooling fan under the cells to help temp stability and seems to do a good job. They also do a 10 minute version, the Digispeed 4 Ultra, but I haven't tried it, being a little wary of charging too fast.

Ansmann also do a really useful battery holder for us forgetful types, that have empty and full orientations printed on the side of the holder, to help you remind yourself what state sets of cells are in.

If you want a tiny but effective charger for up to 4 AA cells, you could get one of these:

I have one that I take everywhere. It's not as quick as the Ansmann, but for use of space it can't be beaten. It's multi-voltage too.

 

As for the cells themselves, my 2700mAh NiMHs are own branded from 7dayshop, a UK bulk web outfit. Since all of my NiMH cells, from various manufacturers have the same problem, I'm tending to believe its more of an Inon machining issue than a NiMH cell size issue. We'll see though.

 

You can test your battery compartment quite easily. Hold the strobe upright so the compartment is uppermost, as if you were pointing the beam horizontally. With both covers removed, take a cell that you know works fine and gently insert it in the "bottom left" opening. This is the one nearest the strobe body, that takes the cell with its +ve terminal (the nipple) pointing outwards, towards the cap.

 

As you slide the cell home, just before it reaches the base contact, you may feel it hit a small ledge, and hop up as it finally comes to right in the right place. If this does happen then you might have issues with thick, square-edged cells.

 

I hope that helps people.

Thank's everyone

 

I ordered a Maha MH-C801D charger that takes eight AA:s at a time and is supposed to charge them (2700:s) full in about one hour. It seems to be of a convenient size as well.

 

Also ordered a few packs (16 cells) of Maha 2700:s, allthough some have reported problems with them. Will test them thorroughly before I take them somewhere though and if they don't work properly I'll buy another brand and demand refund.

 

All came to a total of US$144, which I found reasonable.

 

cheers

Hi Christian,

 

thanks for pointing out that Maha charger, it looks like a good unit for travel, having a multivoltage power supply with a figure-of-8 cable. Being able to charge a full set of 8 cells in one go is great for my pair of YS-110 strobes.

 

Looks like there is a place importing it to the UK, at a premium of course. Luckily my girlfriend is going to Boston next week.

I ordered from their web-page. 2-3 days later DHL (I think it was) knocked on the door with a package.

 

Shipment was included in the US$144 I mentioned, think shipment was something like 20 dollars.

I just got the Powerex MH-C801D charger and Powerex 2700 mAmp batteries from Thomas for my Inon Z220s. Works well above water so far.

 

To Frogfish-Why not order from Thomas and have them shipped to where you are staying in the Bay area. Let me know if I can help.

Just came back from Mozambique. The MH-C801D and the Powerex 2700:s worked flawlessly with my strobes. I'm totally satisfied and can truly recommend this package.

another charger that's about to come out, is the Maha MH-C9000 looks very good.

 

the other maha option is the MH-808M which is great if you have C or D cells that you also need to charge, I've used one with 12ah D cells, works great.

CDascher, others..

 

Thanks for the offer of help. I've just found Thomas via google. First thing to find out is whether they will honor my credit cards. They're both perfectly good gold Master and gold Amex cards, but it's amazing how many on-line businesses blackball any card with a billing address in a country like Indonesia. I've had a lot of problems buying stuff made in Asia and getting it sent to me.
