    DECT phone batteries

    DECT phone batteries 11th Jul 17 at 11:02 AM
    One of our Panasonic DECT phones has died - it needs replacement batteries
    The existing batteries are 2 off 1.2v Ni-MH 550mAh SHORT - code HHR-55AAAB
    Will https://www.amazon.co.uk/Panasonic-micro-Battery-HHR-55AAAB-1000mAh/dp/B00SXAS8XU be compatible or will 1000mAh be too much to charge ?

    Yes they are compatible, 1000mAh is the storage capacity so they will last longer off the charger base.

    Unless you make very long landline calls, I suggest that you buy 2 x AAA rechargeable batteries from Poundland for £1.

    They are lower in capacity, 350 mAh I think, and might not take as many recharges but they should be fine for a DECT phone that is usually kept on the charging base.

    350mAh is too small

    Ones I saw in Poundland were 600mAh (I bought some for speaker and work great)

    If you want to save yourself the trip these 600mAh are £2.15

    www.ebay.co.uk/itm/191706371559

    and these 750mAh are £2.95

    I have never had a rechargeable leak and I have used loads, not read battery university site but I would not be surprised if they don't leak acid, sure they can do other things but a shop like Poundland would not risk selling dodgy batteries.

    In a recent Which magazine, they reviewed both AA and AAA size rechargeable batteries. The top AAA size performers were:

    Panasonic Eneloop (not the "Pro" version)
    Duracell recharge plus
    Energizer recharge power plus
    Energizer recharge extreme

    The tests included measured capacity after dozens of cycles, some such as Morrisons and Maplin own brands didn't fare well.

    There were no tests on pound shop batteries...

    Of course an 800mAh battery will always perform better than a 350mAh and there is no doubt that with a brand such as Panasonic and Energiser you are paying for a certain amount of quality control.

    At the same time I would NEVER buy the fake batteries that quote fake mAh figures over 2500 and some even as high as 10,000, when tested on YouTube they were found to have no protection circuit and after 5 discharge/recharge cycles produce around 500mAh.

    However, there is a level in between and I have found the Poundland 600mAh perfectly good.

    My concern with Dect phones is how reliable the chargers are and whether they would damage the cells.

    It would be good to see Which to a like for like test on the Poundland batteries as well as the charging of the Dect phones.

    I tend to take that view too, but I've had Duracell leak in both the cycle lamp and the TV remote. I've just renewed the laptop battery though, and I forked out £97 for a pukka Samsung one rather than buy an arsonist from Amazon for £25

    Testing batteries over a few cycles is incredibly time consuming, not to mention tedious. The problem with "shop brand" OEM batteries is that they can be manufactured by a number of different factories and may differ from one factory to another.

    While the Which people tested a range of brands, 14 x AA and 14 x AAA, where do you draw the line? In the case of the Morrisons AA batteries, after 87 cycles they were down to 60% capacity and the test ran to 200 charge/discharge cycles... phew!

    I have a Westmountain CBA computerised battery analyser (http://www.westmountainradio.com/cba.php), I have done a limited amount of battery checking, but life is too short to spend much time on anything as trivial as batteries for a cordless phone.

    My most recent test was on a pair of Power Sonic 12V 4.5Ah batteries used in a hedge trimmer, they are 7 years old and measured 4.1Ah on a 450mA discharge (takes close to 10 hours)... not far off the specification of a new one.

    You can use Imax and similar chargers to run repeated charge discharge cycles
