Can the F56 board be used on 5400HS? Any idea?

Yes yes Bro , i know enelope batts can use other charger to charge . I am saying the Max power output of the charger ... Or am i wrong ... ? :unsure:

After reading from the Sanyo site , think i will have to post at B&S section to sell away all my Current RC Batts & chargers & change all to Enelope . :lol:

The max output of the charger only determine how long you need to charge the battery (unless the voltage is very different). Given the same charger, it will take longer to full charge a 2700mAH battery as compared to a 2100mAH.

The faster (1 hr charging) you charged up the battery, the hotter the battery will get, the shorter its life span. As for self discharging, it is how the battery is designed and manufactured.


Bro clkoh, sad to hear wat had happened to your F56.

Thanks Bro Chee Yong ! Explaination noted . :thumbsup:

2700 means a faster recycle battery not powerful..

For Heavy flash user, try not to go for the higher and MORE powerful battery.

the 2700 battery allows your flash to recycle faster not last longer, it burns the board faster too since its faster. I don't know about the 56, but when i using the 5600 in the 2300 battery era, it works fine... when i start to buy new and faster battery, it gave me slower recycle time, which means, my board in the flash is wearing off...

If you have the battery pack to go along with the flash, advice able is to use all the same voltage , ie battery pack with 6 pieces of 2700 and flash 4 pieces of 2000,etc.... if u mix the 6 batteries in the pack with other voltage, u will have more problems with the flash.

Everyone know how to take sharp photos with good lens, but do u know how to take good blur photos with fantastic lens?

I prefer Nikon's flash as they can go sweet multiple shots...

so far, only the 5400 can do that when i use it MANUALLY... the 5600 and the 56 seems to be the same build when i try them both. I hate the recycle time for the 5600 and the 56...

Manual Flash at less it LOST the TTL function but still when use only half power, its still fine... and work on FULL half power. do the recycle time is faster and the battery power last longer.
when using the 5600 half power, the TTL cuts of the power even more because it includes the distance since the TTL is functioning...

I beg to differ on some points mentioned by Bro BC,

here is my lengthy explanation.

the xxxx mAh that was printed on the battery is the capacity rating showing it max mA output for a duration of 1 hour. Therefore, as an example, 1 milliampere hour (1 mAh) is one thousandth of an ampere delivered for a duration of one hour. So if your device draws 1 mA, it would last 1 hour. so for a 2700mAH, it would last for 2700 hours.

The time to charge up your flash the first time (with the flash tube and its internal capacitor totally discharged, so called brand new, charging up your flash for the 1st time after a long non-use period etc), it should be the same if you are using a 2300 or a 2700 (fresh).

Subsequent recharge is a different story, depending on the amt of flash, always in full power, the amt left in the capacitor to charge up the tube, etc . This has more got to do with the design of the flash circuirty than the battery. The 2700mAH being a higher capacity typically can provide sufficient amt of power required for charging as compared to 2300 after a while of use.

That is why THEY come out with the external battery pack to reduce the recycling time to almost half the time required by the main board. Pay 200+ dollars for the EP-2, is for the high voltage transfomer, that provides a 300Vdc directky to your flash tube.

As for Bro BC's flash wearing off. It is not likely your circuit board, but rather is the capacity or the flash tube (age liao). Electronics components do age.

Agree with you on no mixing of different capacity rechargeable battery. ALWAYS have the set charged and use at the same time and replace the whole set of 4 or 6 batteries when 1 of it has deteriorated. this is to prevent damage to your device (just good practice adopted)

What I've said is based on ideal situation. There are manufacturering minor defects, battery could have been left in the store for a long time, battery memory lost etc how the flash was used, was the flash circuit board well made, too many conditions.


:D :D :P

thanks for the technical explanation it does help. how much ma does the 5600 or the 56 draws?

My experience using my wearing off 5600 and the 56( of no idea how often the user had use)on the same set of battery fully charge on the 2000 eneloop and the sXXXX 2700 battery on the recycle time is slightly different,

ie, Full test blast took 12s to recharge on my 5600, 10s on one of the 5600 on both sets of battery. 8s on the 2000 and 7s on the 2700 for the 56

Which i guess the 56 consider the youngest among them.

As for how long it last, i would say the eneloop is better in terms if i have charge them the night before and the rate i am using. of course i didn't do the time check, but as the user, i can feel the difference. The eneloop does last longer than the 2700 as i can feel the different even when i started to use the eneloop.

in short for my case. its eneloop and OLD wearing off flash last longer than new 2700 and new flash....

Wow .. lengthy discussion here!!

Chee Yong, the Flash are called 5600HS and 5400HS for a reason.

However it is definitely possible to swap parts between Minolta 5600HS and Sony's F56AM. As for 5400HS, I doubt very much... Guide no different physical size different, shape different ..

Thanks bro Clkoh.

I just want my 5400 to work in the wireless mode with my 5600 (off camera). :( :( So trying every avenue possible at the lowest cost possible.


To the rest, pardon me for that lengthy post. Just got carried away (esp in technical discussion)
Cheers :)
