D1 series Battery

[Nikon D100]

Will like to ask some question regarding D1 series battery. My uncle camera only can take 200 shot after each full charge. he did refresh the battery before but still the same. Orginal battery will be very expensive, while east gear battery perform is unsure.
heard that someone modify this battery with lithum battery before, so wondering can any one tell me how to modify this battery, or can any one give advise on this battery. Thank you.

If your uncle is fine with ebay, there are some ebay sellers with OEM EN3 battery packs at a pretty reasonable rate. Just need to be sure to count the cost of shipping. Alternatively Heard that BatteryBarn is quite good as well.

Alternatively... send the battery to the battery shop in SimLim Tower basement. Then can replace the cells for you and the currently cells are of a higher capacity which would really can hold charge much longer.

Btw, Yesterday i did my very own modification. 2 wire was solder to the connecting pin of the battery and branch out from the battery. I connected 6x2300mah to the wire. AND I FAILED!!!

I bought from Unicell (at Sim Lim Square) #02-70 an OEM EN3 for ~S$30 ...

Oh thank you for your info. but may i ask is it they opened up your old EN-EL4 and replace with the old battery with new ones or they have OEM EN-EL4 that can fit instantly to your camera.

Hi,
Can u share a bit on opening the casing of the EN3. I have one which needs to replace the battery as well. sykestang suggestion is good - have to source for one with good pricing, the shop at the basement of Sim Lim uses machine soldering (therefore may cost a bit more).

Maybe you would like to tell us what kind of battery these 2300mAh ones are and how you connected them up and what you mean by failed.
The original EN-4 battery is quite simple, electrically. It's just 6 cells wired in series.

EL-4 is for the D2 series. Do you mean the EN-4 (for the D1 series) ?
Anyway, the OEM one that he bought is probably just a replacement pack, meaning with casing and everything, no need to DIY anything, but it's still NiMH, not Li-ion.

EN3 for the Nikon E3 series ? Dunno how different it is from the EN-4. Anyway, I opened the EN-4s using a tool called the Olfa P-cutter (you can get from stationery shops). It is used for scoring and cutting plastic. There are 2 sizes of this P-cutter, the larger size cuts faster and wider but the smaller size one makes a narrower cut (slower but recommended). How you use it is to score (very gently at first) around the join lines where they glue the 2 halves of the casing together. You need to be very patient and score gently many, many times until the groove becomes deep enough for you to separate the 2 halves. If you use too much force, you will break something or cut too deep and damage the insides.

It was the OEM EN4 that is complete, no need to bring down your old EN4.
In fact, I've converted 2x old EN4 to use Li-Ion (2 cells, 17650 bought from unicell) and mod a Nikon MH-53 (number might be wrong, but it is the charger for ENEL1) to charge it. Will put up photos at a later time ....

The battery shop is exactly at the basement from the staircase. Whole shop sells batteries. Last time I change there is ard $70, but not sure the price now.

You have to bring along your old battery and they'll actually replace the cells inside for you. Takes 1-2days.

If not wrong, Unicell does have a factory to do machine soldering for you also. Have not check their prices before as current all my batteries have not reached re-change age.

Unicell is recommended as I've bought many kind of batteries from them before, from UPS to my potable powerpack strobe replacement cells, and so far none failed. Unicell is their own brand and have established in SG for the past over 10yrs already.
