Z1 Overnight Replacement Battery

These things could not get me through a whole night of operation beginning with the first time they were charged.... A complete waste of money. more...

Z1 has discontinued its 7050 battery, it appears. I suspect the reason may well be that those batteries exhibited a... quirk that caused them, when depleted, to 'go to sleep' and not respond to recharging efforts. I'd heard that they could be sent to a manufacturer's site to have them awakened - but, fortunately (after some customer care escalation at cpap.com) my non-performing HD7050s were replaced with the extended version. I'm still curious about whether they 'go to sleep' when depleted, and am hoping I don't have to find out from personal experience. I am grateful that cpap.com took my issues seriously and dealt with them successfully. I'd be interested to know what 7050 vs 7060 battery observations others can offer. more...

I bought two batteries with my Z1 and have been able to get two nights out of each one, with... a little room to spare (although, this may be the result of my personal settings). So, with 2 batteries, I've been able to do 4 to 5 nights before recharging. more...

The battery does take a while to charge, but does provide the 8 hours advertised.

fine.
