Why I do this!

Apologies, but a bit of self indulgence in this months blog. Every now and then it is good to take stock and just reaffirm why I do what I do!

I offer a battery consultancy service allowing my clients to access my experience of over 36 years working with, and developing advanced battery solutions. Benefits include;

• Accurate battery type selection
• Improved product performance
• Superior integration of the battery into a system
• Selection of the best supplier
• Reduced costs

Having worked for one of the largest manufacturers of battery solutions in the UK for so long, I often found myself meeting clients who, although they had a good idea of what they wanted, did not know all of the options available to them. Of course, my advice had to be tailored to the product portfolio of my employer. It was very frustrating knowing that there were better options out there from other battery suppliers that, until now, I could not promote.

Most development and design engineers will have spent some time learning battery basics and followed this up with looking at the various articles available on the internet covering battery matters. That’s fine if the battery manufacturers are putting like for like data in their publicity. But they don’t. This makes comparing products very tricky.

Knowing how a particular battery responds to the loads and environments required, especially whilst you are still developing the product is tricky. Yes, a supplier will do some lifetime and performance calculations for you, but if the goal posts are moving as your product develops, they will not be as keen when you go back again and again asking for the calculations to be repeated. Of course they will do it with a smile on their face, but this activity has a cost, and you can be sure that it will be recovered eventually.

So how much more convenient it would be to have access to someone who can do these predictions for you before getting a potential supplier on board. Especially as you will know they are working for your interests and not those of the supplier.

I look forward to helping you in the future!

Careful thought needs to be given to the interaction of the battery, the device it is powering, the environment it is operating in and the skill set of the eventual user. The availability of ever more powerful and energetic batteries, and the rules and regulations regarding transport and disposal, mean that battery selection is not as straightforward as seems at first. The use of an independent expert to give guidance to your design team can save a huge amount of time and cost to new project development.

Time to put the tinsel away!

Okay, it is the time of year to put away all of your festive decorations. Pile them into a box, seal it up, then stuff it in the attic. Yes?


What about all those decorations that are battery powered? Please remember to remove all batteries before putting the flashing reindeer, dancing moose or twinkling fairy lights away. Leaving them in runs the risk of leakage with the result that your favourite laughing Santa gets a serious case of heartburn!

Also remember to keep ‘sets’ of batteries together. Do not mix up partially used batteries from different displays. When you come to use them again you will be fitting batteries with differing states of charge. Running the weakest battery into deep discharge, as will happen mixing batteries of differing states of discharge, is likely to result in leakage and damage to the kit being powered.

If storing the batteries for use in a years’ time, make sure they cannot short out by contact with others. My tip is to put an elastic band around each set of batteries removed so all are pip end up, then put each set into individual food bags. These should then be stored in a cool dry location.

Battery management is often overlooked but is an important aspect of providing safe and reliable portable power. Making sure a new product is matched with the correct battery technology is an important task. DM Power Solutions can identify the best battery technology for your new kit and advise on the appropriate methods of management to get the most out of that selection.
