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.
