Correct NiMH battery charger

[eera5607]

Hello everyone. I have a GP NiMH charger with the specifications shown in the image below

I also have two pairs of Energizer NiMH rechargeable batteries with this characteristics

Can I charge them with the GP NiMH charger?

Thank you!

Yes, you can.

 

300mA is a perfectly reasonable charge current for modern NiMH batteries. You'll fully charge the batteries in about 6-8 hours.

thank you! So there's no problem with the 2.8 volts output ?

No problem.

niMH batteries are 1.2v nominal, ~ 1.35v when fully charged.

The voltage has to be higher than max voltage to charge so 1.4v per battery (2x1.4=2.8v) is perfectly reasonable.

One last question. Can I charge only one battery? Or do I have to charge both batteries always together?

always charge 2 at a time
