DECT batteries

[caveman]

Must you buy dedicated DECT phone rechargeable batteries. Or are any NiMh rechareables OK.

I'm just using standard rechargeables. But then that might depend on your phone, and it's charger system.

If originally designed for NiCad battery technology, the charging system may not be appropriate for NiMH. Smart charging needs a more sensitive endpoint detection for NiMH, since NiMH generally have a flat delta-V endpoint rather than a dip. Dumb trickle charging is probably equally poor for both technologies.

Not sure if you can still get NiCad, I thought they were banned now, though a few places still seem to have them.

We had those - ended up charging batteries in a charger as the phone charger didn't.

As Matth said as long as you get the same type of rechargeable battery (usually 550) they should be fine.

i got some for a friend of mine that couldnt even get them in places like maplins on ebay.

they were also a damn sight cheaper than what the manufacturer wanted.

The NiCd batteries in my Binatone DECT have failed and the charger simply refuses to deal with the NiMH cells I have replaced them with. I had not twigged that NiCd had been phased out. Bu@@er.
