My battries died on me more then once recently,,crap timing,lost on a remote spot in Donegal and the battery pack dies,this is after charging them fully the day previous.

I have the extra battery pack for the D90 that holds two batteries,one is the battery that came with the camera and the second is one from ebay.
When I check the in camera battery check neither would be a hundred percent.
Both show usage around the 65% they die quickly,in saying that they charge very quickly which leads me to think somthing isnt quite right,,

Q,How can I check the battries individually?
Q2 Is there a possibility that it might be the battery pack acting up ?
Q3 How long do batteries last,,the original battery with camera being about 5 year old,,

Any sort of insight would be great on this subject,

Thanks Aidan,,

I have heard stories about some Grips/ Battery packs (especially third party) causing premature battery charge loss. Charge your batteries, remove the grip and try again.

Hi Aidan,

Dependent on use 5 years is an expected time for batteries to start to fail, the problems you mention certainly point to one or both batteries having problems.
I would take the battery pack off and use the batteries in the camera individually, Then you will have an idea if one battery or the pack is faulty, I suspect it is one battery dragging the other down.
The other option is can you fit just one battery in the pack and see how long it goes for.

The most common fault with batteries not holding charge,or showing low rate when charged is sadly down to poor use by the owner.
To get the best out of the modern battery packs requires that they are FULLY discharged before recharge, sounds obvious but many people stick the battery on charge when they get home from a days shoot or charge up prior to going out, regardless of the batteries current capacity.
This sound ideal, trouble is if the battery is actually at say 30% charge then it can only accept a 70% charge.
Couple this with the batteries having a tendency to remember charge rates over a period they will only accept a low rate of charge if they are continually re-charged before being FULLY discharged.
First re-charge was 70% next time say at 50% use you are actually re-charging at 35% of the batteries full capacity (50% of 70%) and hence over a period of time the battery looses its abillity to accept a full re-charge
To overcome this ALLWAYS allow the battery to fully discharge before re-charge, this can be either by useing the battery in camera till it reads empty or, and this is more likely to prolong life, attach the battery to a low wattage 6 volt bulb (car sidelight bulb is ideal) and wait for bulb to extinguish, this could take a while.
I have several batteries that are well over 7 years old and treated like this I have never had a pack fail me

I don't know of any major camera manufacturer that makes its own barreries. They're bought in from a specialist and the trick is to buy from the same source if you can. Getting unbranded batteries from ebay is a bit of a lottery. It's better to buy from a fully reputable but cheap source like Picstop, MyMemory or 7 day shop.

When a pair of batteries are used in parallel, the weaker battery can drag down the stronger. Could you remove the grip and just use the battery in the camera?

When working with several batteries in a pack, it's best to assemble a set that's the same make, same type and the same age that always work together. Label the batteries "set A" etc.

Do as Newdigit suggests.

Out of habit I prefer to fully discharge batteries before re-charging, but I have been reliably informed that modern batteries have much less 'memory' than they used to so it is far less critical than even a few years ago. However for a new battery they still recommend 4 to 6 full charge/discharge cycles before they reach maximum efficiency.

If you're going to leave lithium batteries unused for long periods of time they should be stored in a half-charged state. Also, the batteries will last longer if you don't fully discharge them.

Correct. The "advice" about letting them discharge completely before re-charging is well out of date.

But the OP's batteries are 5 years old, so may not be modern versions. In any case 5 years is more than I would expect from any rechargeable battery.

Generally speaking, I have found cheapie Chinese clones to be as good and reliable as Nikon's own - but I have never kept a digital camera for more than three years so have never yet experienced battery failure. The only slightly annoying factor is that every Nikon dSLR I have bought has used a different type of battery from the previous one.

Just why do manufacturers to that?.......If it isn't the batteries, it the flash memory, CF to SD. I mean I know they want us to part with more money, but as you say it's really annoying especially if you're fortunate enough to own 2 or more cameras that are slightly different models. Another con is the battery grips not being cross compatible....GRRRRRR! Sad

The electronics in a decent quality battery give you efficient charge monitoring which reduces the battery charge memory problem.

All battery technologies have different optimum charge levels the one thing I am sure of if you fully discharge lithium ion batteries before every charge you are vastly reducing the life of your battery.

Ridgeway, my advice would be bin the eBay battery buy a new manufactures battery and keep the old original as a spare don't use them together.

If you can't afford a new manufacturers battery because let's face it they are extortionate then buy 3 Chinese copies and enjoy them for as long as they live.

The advice to completely discharge, is for NiMH AA batteries as used in flashguns. There are chargers which will do this automatically. EG the Technoline BL700.

The modern Lithium Ion batteries, as previously stated, should NEVER be completely discharged.

I've found that the 7dayshop batteries are better than the Canon originals I have had, admittedly they don't get very heavy usage.

Maybe I've just been lucky, but I would just buy some new ones from 7dayshop and use them as you please. They don't cost a fortune so if they do die after a few years usage it's not the end of the world.

I've got several made by UniRoss that were purchased from 7DayShop and they've proved to be much more durable than the Canon own brand equivalents.

Thank you gentlemen for your insights and eye openers,
I am going to drop the battery pack and find the weak or old one.
Then I am going to purchase two new batteries of which make I am not sure they will be of the same type/brand.

Thanks for all the information,,;SmileSmile

Cheers Aidan,,
