I’ve opened the device and am looking at the soldered on battery pack (2xAAA). . How close do I need to match the batteries (Suppo HSY-AAA0.75-PHP) in it? Is any sort of AAA 750mAh with the same dimensions and solder lips alright? Can I use normal rechargeable AAA’s and solder lips to it or anything?
Hi @sjakila_ , As long as they are NiMH AAA rechargeable batteries it will be OK. Having batteries with solder tabs - example only is prudent so as to make for an easier connection because without them you may have to apply too much heat to the battery when you go to solder them back in. Having larger capacity batteries would mean that it would last longer between charges but conversely it will also take longer to fully charge.
Just now I removed (tore) the old batteries. Put two aaa nimh 750 Mah amazon basics rechargeable batteries and charged for just 15min. Had a shave. The battery indicates orange. I will charge for 8 hours in a fire safe place and test. Will update tomorrow.
