Can I use a Ni-Cad 3.6V 700mAh battery for a cordless phone that specifies Ni-Cad 3.6V 600 mAh ? I’ve been searching forever for a battery, so decided to try the 700. When I inserted it, lights started blinking & a high pitch squeal sounded. Maybe I should continue to search for the 600. The prongs fit, so I thought it might work.
The squeal maybe due to feedback. That is if you have a speaker phone and you kept the speaker and the remote unit both on at the same time and near to each other - it will prolly sqeak if there’s any sound,
The battery sounds fine - make sure you have the polarity correct.
Thank you so much, ** PhilAlex ** and andy_fl. I have the phone now recharging, & I’ll see what happens in the morning. I had stopped at an electronics store today, but they were out of one they said would fit. It was only 300 mAh. Then I found this one at Best Buy. Twice the price! But after looking up Milli Ampere Hours (thanks PhilAlex), I see that it has more power. Or that’s the way I interpret all of this. Thank you again, gentlemen (or am I assuming again?). I will sleep well tonight.
