Is driving with no alternator safe?

My 1 year old POS Denso alternator locked up, so I've been removing my battery and putting it on a charger daily until the replacement alternator arrives. I took the belt off since the alternator locked up. The new/used alternator should be here the 19th. The battery is an Optima yellow top D34, so it's a deep cycle and it won't be damaged. I am driving 60 miles daily with no accessories on besides my Scanguage, and all my lighting is LED, so it doesn't draw much power. The battery still has plenty of charge left when I get back home, and I have an extra fully charged battery with me just in case I get stuck in traffic or something. Is this safe? I'm worried that something may be damaged from running on too little voltage. Is something getting damaged a valid concern? I know I won't get stranded, so is doing this for another week until the replacement alternator comes OK? Thanks.

If you plan on keeping the car consider buying a used (Honda OEM) alternator from a local junkyard ($30) as a spare.

It's pretty easy to break-off the positive terminal threaded stud during removal or installation.
