PanasonicEvolta 1600 Cycle AAA Rechargeable Battery 750 mAh stay-charged

I have not had the batteries a long time so can not rate the length of use before recharge needed. I have had no problem with them.

I bought these batteries because I needed rechargeable Panasonic batteries for a charger I bought over 10 years ago. I have been unable to find the same batteries and did not want to risk buying batteries that would not work. I read the product description on Amazon and it said "Good for all devices". I am happy to say it's true & even happier at the fact that I did not waste my money (especially due to the fact that I'm from the Caribbean and the return would have been a bother!!! Happy, happy, ohhhhh so happy!

After fully charged 4 AAA batteries, put two in a device two days later, and it could not turn on the device. Tried the other two batteries, same result. Charged all 4 again, this time worked, right after fully charged. Two days later, out of battery again. Put the other two unused in device, also out of battery. Put in regular non-rechargeable AAA in device, then the device can be turned on. Don’t waste your money.

These batteries nearly cost me about £70. On arrival I put them in a cordless phone that wasn't holding its charge too well . and still the phone didn't work. That's it I thought, must be the phone, must get a new pair. Being a belt and braces type of chap I thought to test the new batteries and all 4 were flat. The packaging stated Ready to use AND that they hold their charge for a year. Should send them back straight away but to try and avoid the hassle I'm seeing if they will charge up and then hold the charge. Total failure to meet claimed performance

Purchased these batteries to replace worn originals from Panasonic KX-TG2722 ECO handsets.Batteries appear to be charging only one of the handsets, but the other appears to be faulty and is stuck showing status as charging BUT Only (1 bar) symbol is showing on handset.Am currently looking to see if handset or base or battery is faulty and will update again.Good price for rechargeable batteries.cheers

Good product. longevity obviously depends on usageMini Maglite torch, on candle mode last for approximately 4 to 5 hours using candle poweruseful for bathroom, and definitely saves on pull cord usage which can detrimental to switch longevityAt £8 for 4, they recharge in a fast time (about an hour) using the Panasonoic BQ-CC65 charger, which is an excellent charging product

I purchased these batteries as replacement batteries for a Panasonic telephone. The old batteries only seem to hold charge for an hour or so, after changing batteries the phone is back up to its former capacity.Worth buying to save yourself the hassle of having no charge.

Just thought I would try replacing like-with-like batteries in my BT hands-free, before I purchased a new set of phones. After months of being frustrated by all 4 phones either dying on pick-up or in minutes, with these new batteries they are working perfectly again.
