4.0 out of 5 stars Unadvertised battery replacement, October 8, 2011
Verified Purchase(What's this?)
This review is from: Philips AVENT Basic Baby Monitor with DECT Technology (Discontinued by Manufacturer) (Baby Product)
As many others have noted, the clarity, coverage etc are generally pretty great. We upgraded to this from some analog radio unit and it's MUCH in terms of noise, volume, sensitivity, etc.

.... until about 3 months ago!

After just over a year the volume wasn't always high enough, the battery would run flat quickly and when charging it'd make a lot of weird static noise for 10-15 minutes while the battery was completely flat. Very frustrating. So only 4 stars.

Today we went to look for a battery replacement but couldn't find any here or on the Philips site. Now Philips have EXCELLENT customer service, so they probably would sell one if we called (or based on past experience with other of their products, maybe they'd just mail one for free); but it's Saturday night and I just wanted the parent unit to work properly again.

Armed with two rechargeable NiMH AAA batteries, a paper clip, some tape, a utility knife and something to cut the paper clip you can replace the battery in a few minutes.

Take the "battery pack" out, use the utility knife to cut open the paper tape wrapped around it and then squeeze, tweak and push the batteries out. I broke the plastic enclosure a little in the process, but as long as it's mostly intact you'll be fine.

The batteries will be attached together in one end with a small bit of conducting metal. It's soldered on, so you probably won't be able to get it off and re-use it. That's where the paper clip and tape comes in. :-)

Put the new batteries into the enclosure (pay attention to the + and - ends, they point in different directions when inserted into the pack), tape a small piece of paper clip (or other conducting metal) to one and put the pack back in the parent unit. After I broke the plastic in the battery pack, it'd sorta fall apart taking it in and out, but if you just get it in, there's so little room that it'll stay in place just fine.

... and if it all fails, you can just call Philips and order a replacement pack the next business day. :-)

Thank you! I actually was going to shell out the $ for the Philips replacement battery, but they are out of stock! this is very helpful! My only worry is what happens if I break the enclosure and then have nothing to use. :-(

After pulling out the battery you can check if it'll work with power plugged in (but no battery); then you have that as a backup in case you end up needing or wanting the official Philips battery.

That being said; I broke the plastic "enclosure" a bit taking it apart but nothing a bit of tape didn't fix well enough. After you stuff it back in, it's all fitting pretty tight so unless you take it in and out a lot (no reason to), it's no real problem.

We're still using our "upgraded model" with the Sanyo Eneloop batteries two months later and it's working better than it did new.

I had the same problem with the battery and replaced them with a couple energizer AAA rechargeable. I used a staple from a staple gun because it's a bit flatter than a paperclip and worked great. Thanks for the tip! Saved me $25.

Bjørn, you are a genius! Thanks so much, you just saved me a lot of money! I took my sharpest knife and cut the old batteries apart. Not only did the plastic enclosure come through without any damage, but I was also able to reuse the small bit of conducting metal along with some scotch tape. No paper clip or staple necessary! Of course, if I had been trying this without all the feedback here then I'm pretty sure that would not have been the case. THANKS EVERYONE!

Thank you so much. Philips Avent no longer has these batteries. We were able to get rechargeable AAA's already soldered together at Batteries Plus for $1.09 each, my husband rebuilt the battery pack, and now we're in business again!
