• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Charging Modern Batteries in High Ambient Temperatures.

During the UK's short excursing into High Air Temps and relatively high humidity recently, I had occasion to place several small gardening appliance batteries on charge.
Now even at 'normal' UK temps, these batteries often have to spend some time cooling down before the chargers will deem it safe to start inputting energy.

In a couple of instances in said heat wave I had the impression charging wasn't going to happen until I took deliberately steps to speed up the cooling of the batteries and charger.

Has anyone who has to use these devices in a work environment seen problems with on site charging from power packs etc. on such days?

It also started me thinking about Power Banks in Lofts etc. are we getting into the realms of spending a significant amount of energy cooling the battery so that we can use it or recharge it?

I bought a new AK30 battery for my Stihl mower last week and left it in my truck for a few hours before putting it in the charger. The status LED on the battery immediately turned red and it would not charge. I took it back to my local Stihl dealer where I bought it in case it was a defective battery. The store owner recommended I put it in the refrigerator for 30 minutes and let it cool down before putting it back in the charger because it was definitely to warm. This worked and I've mowed my lawn twice since without charging.

I normally keep batteries to my lawn machines and tools in the basement until needed.
