Batteries NH-10WM, NH-14WM, and charger BC-7HT

[Hugo]

Hello everyone,

I bought a couple of gumstick NH-14WM batteries for my MZ-NH900 recorder and also bought a Sony BC-7HT charger for them.

In the instructions for the charger say that charges *ONLY* NH-14WM, NH-9WM, NH-9WM(A), NH-9WM(S) and NC-6WM batteries.

I was wondering if it is safe to use the charger with the NH-10WM provided with the recorder.

The only difference I find between the NH14WM and NH10WM batteries is that one is 1400mAh and the other is 900mAh.

There is written on the NH-14WM battery: "Use only with sony battery charging system designated for NH-14WM". And the same on the NH-10WM, changing the text appropiately.

So, there are four warnings (including the one in the recorder manual for charging batteries with the MZ-NH900 unit) about interchanging different batteries for charging.

Being both gumstick batteries providing 1.2V, I would think it is safe to charge any on either the charger or the recorder. But I want to be in the safe side by asking first.

Any help?

Thanks!!

Hey mate, I don't know how I missed this.

Anyway, it's safe to use the charger with that battery, but I don't suggest using the battery. You'll have better functionality and life with the NH-14WM, depending on the mAh.

The BC-7HT will charge any gumstick battery, even those not made by Sony. A battery is a battery is a battery. :happy:

Although, I think it would take less time to charge a 10WM (1000 mAh) than it would to charge a 14WM (1400 mAh). I imagine this charger could also charge those Mashi Maro 1750 mAh batteries as well...

I'll use the charger always from now on. That was the point to it: being able to keep the NZ-NH900 playing while having a battery charging in the BC-7HT.

Thanks for the info!
