Hearing aids on Shabbos

My mother has hearing aids that have to be charged daily. When she first got them, she asked a Rav what she should do on Shabbos, and he told her to set the charger to a Shabbos clock and put them in and take them out when the charger is off. He also told her to take them out with a shinui. Problem is that recently there are 2 changes in how they work. 1) if after the power goes off to the charger they aren't removed from the charger within 5 seconds, they turn off (and since she's trying to take them out with a shinui, she often can't get them both out in time) 2) Even if the power is off, when she removes them, a light goes on What she asked me was, if anyway she is relying on electricity being drabanon and a shinui, can she just take them out when the charger is still on? (the circuit would break, and a light would turn off) She also mentioned to me that women come over to her house on Shabbos afternoon to say tehilim and its embarrassing for her when she can't really hear them. It seems that the question boils down to, can you lechatchila rely on two drabanos bmakom kavod habriyos on a permanent basis or should she try to buy a pair that has a longer battery life(A new set costs around $2,000. They can afford it, but its still very expensive) Sorry for the long question. Thank you for you help

Shalom!

Thank you for your question.

If this is the only hearing aid that you have then you can use it as you have described by placing them in the charger that is not yet on then removing them with a "shinuy" while it is on and the light will go off. However, it would be better if you would buy a pair of hearing aids that has no Halachic issues.
