Volts Too High Error and Replacement Batteries in HC-2 with photos

(1/3) > >>

William Brillinger:
In December 2020, my original HC-2 was throwing a charging error: "Volts Too High" whenever it was plugged in for charging.
I sent it in for battery replacement. It was a bit over 6 years old when I sent it in. Ring replaced the batteries at no charge.

This week, my second HC-2 started having the "Volts Too High" error as well. It is also about 7 years old now.

Recently I have heard that Ring has started charging for replacement of the batteries on these older HC's. Shipping both ways plus a small parts and labour fee adds up fast.

So... I cracked open both of my HC's to see what batteries were in each.

Original batteries: Rayovac AA 2400mAh NiMH 1.2v

     



Replaced batteries: Tenergy Premium AA 2400mAh NiMH





After a little recon, I ordered a new set on eBay for about $10 after shipping.

Hopefully this info is helpful to anyone else who has an older unit in need of batteries.

Cheers!

Good to know! Thanks Bill.

A good timely reminder Bill; the batteries in my original HC-2 are coming up to 8 years old now and won't hold charge for even a day. Time to replace them. If only eBay here had some good priced quality batteries and not be awash with 2 dollar shop* listings of battery capacities of dubious claim.

I don't get any error charging though.

* Insert 99 cent store in place of 2 dollar shop and most of you will have the right idea.

I recently stumbled upon a trick to completely discharge the HC batteries. On the main page of the HC down at the bottom of the screen is an "adjust settings" box. Click on that, then you will see a line for Auto power. Click on in to get to "disabled".

That will completely drain the batteries, and allow you to completely charge the batteries. To help it happen faster I also crank up the backlight brightness. Just remember to reset the box to "enabled" after you are done.

I will admit to not researching this earlier, so If this was discussed before, I apologize.

Ok to put peoples minds at rest, Ah listed on any battery is only a concern if there is not ENOUGH Ah to do the job for any real long period of time. So Big Ah numbers good (mostly, get to that later).
What's more important is a battery or batteries total potential VOLTS. That's whats going to do the most damage the quickest if its to high, why....well here comes the high Ah bit, if you have a incorrect Voltage with a high Ah rating its burns through components way faster than you can blink.
Remember, its the Volts that give the POTENTIAL Difference to commence work, but its the AMPS that do the work and a electrical/electronic device will only EVER draw as much current (amps) as it needs to do the job IF all is well with the device.
So think of it like this, Volts push/pull the amps that do the lifting, ok. (real rough but you get the idea)

Ergo, you want a long running session with your HC, then shove in the damned biggest Ah AA that you can find but for gods sake don't ever get a short !  :D
