DP2 Merrill battery help

Guys, i ordered 2 ricoh db-65 from keyboardshop.in, well, without reading the fine print. 
Today i got the batteries of the similar specs, but not the original ricoh ones. 
Worst thing is, they have somewhat different grooves at the bottom, so the battery goes in but doesn't lock itself in. 
Sigma BP41 has 2 grooves at the bottom which are bigger area wise...
Is there a solution? How do i cut the grooves to make it fit in...
someone who has done this?

My advice is to return it and buy the Wasabi Power Battery and Charger Kit for Ricoh DB-65 from Amazon.

Re: DP2 Merrill battery help

with a sharp knife, you can cut the two notches to the depth you need.  Be careful that you don't cut too far.

I bought  8 of these:

http://www.ebay.com/itm/380347124667?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

on ebay for about $35 total, with free shipping. These are the same batteries that I use in my Panasonic FX150. I used a pocket knife to cut the small notches on the base of the battery as other posters have described. It is quite easy and takes less than a minute per battery. I typically get about 100 shots per battery with my DP2M (depending on usage). They still work fine in my FX150 as well (after the mod). I get about 300 shots per battery on the 14 megapixel Panasonic, so the battery life is fairly linear.

Re: DP2 Merrill battery help

I have drilled it with 2 or 3 and used a knife to cut the plastic with another 4 or 5.  Although hard, it is not tough to cut. I have about 7 or 8 that I have done.  I just use the knife and then pry off with a small flat-head screwdriver.Leaves a hole into the battery case so if you get nervous about it, you can fill it with some plastique.

You can also use a hot knife or hobby knife. It takes a few moments per battery but you do need to be careful and do it somewhere well ventilated.

I bought 2 of the following batteries recently. They are identical to Sigma's own and fit perfectly, no DIY necessary.

They must be available in the USA as well.

This is the replacement battery alongside a Sigma original from my DP2M. Taken with my phone so please excuse the quality.



The replacement fits the camera just like the original, ejects without any problems. no need to modify anything. Hope it helps.

Re: DP2 Merrill battery help

I just realized that your replacement batteries have 3.7V whereas the Sigma ones have 3.6V. Can this cause any problems?

No. It's just a more optimistic declaration of the manufacturer. Voltage will be sucked down by the camera as soon as you switch it on.

Re: DP2 Merrill battery help

I've been using the replacement quite a bit and the camera works perfectly. I work with commercial HVAC control panels and this slight variation, even if it exists, will make no difference whatsoever.

Re: DP2 Merrill battery help

For your info , I got the wasabi batteries for my ricoh GXR  and they last  less long than the ricoh original batteries .

I noticed the same for the third party batteries for my OMD

in top of that the charger is a few mm too short so the ricoh batteries fall of the charger

I know it is a few dollars more but I would not get anything else than the bp-41 or the ricoh branded db-65

Not worth the hassle if you ask me

Re: DP2 Merrill battery help

To be honest, normally I'd say the same thing myself, but in this instance the generic battery is identical, fits the charger like a glove, and works perfectly. I've also been getting about the same exposures per charge as my 2 genuine Sigma batteries. I've really got no complains at all.

Re: DP2 Merrill battery help

Just want to drop in and tell everyone this solution to charge multiple batteries with one charger.
