Question about rechargeable batteries

kee

I've got some Philips wireless headphones where you charge them up in the headphones, and supposedly you can only use their batteries, but not according to this:

"Actually, look at the Philips SBC HB550S battery, the black label on battery isn't going to the end of the battery's "-" side, there's few millimetres of solid metal. Look at other, ordinary rechargeable battery, for ex duracell's. This other battery has label all over battery (from "+" to "-"). So only thing you have to do to make any batteries work with you have to cut and remove this label from battery you want to use from the "-" side of the battery, about 1-2 cm, like philips one has. It's because these headphones have this extra clip in battery sockets, philips wants us, customers, to buy those extra-expensive batteries."

So if I were to try a different brand, the originals were 550 mah (you're supposed to charge for 16 hours to get 16 hours - I'm currently getting 1 hour).

Would it be OK to use a higher mah and if so what is the highest capacity AAAs have (they seem to have less than AAs?) and how much longer would you have to charge them for to get the maximum charge - 16 hours seems long enough already!

Google is your friend

according to here, http://www.buyabattery.co.uk/rechargeable-batteries/rechargeable-aaa-batteries.html?p=1 1100mah for AAA

cant seem to do a search on ebay found out why. some reason if i'm not logged in it wont allow me to search

according to ebay and sellers from HK, its 1800mah.

note: Dont buy the ones with BTY 1000 on them, they dont last long, bought from HK via ebay personally.
However the plain purple ones have lasted 3years so far and are used daily.

Charge time depends on the charger. These are good.

Just remember to get Eneloop type technology, the ones that can be delivered pre charged. This type performs better all round. The Ansmann and Sanyo (or other major known brands) ones are the real deal while lots of Chinese no-name brands also offer this tech but are not as good.

Good advice, also I too bought some of those BTY1000, utter rubbish held a charge enough for about 5 minutes of use.

Purple ones i got AA size have 2800mah on them.
Purple ones AAA size have 1800mAh
cost £10something. for 32 batteries in all, 8 of each AA and AAA total 16batteries.
i use the AAA in my 9xled torches x2, as a test on a full charge and left on, last a decent 8hrs without turning off.
led torches with 9 leds. compared with uniross at 8hr 30min. so not to bad
I was in a battery testing mode at the time.

Bought some Active energy AA 2300mAh from Aldi also pretty good for the value £2.99 for 4
and some Duracell AA 2450mah for £5 for a set of 4

LSD (low self discharge) rechargeables hold their charge for longer in low drain applications. Their total charge tends to be a bit lower than older types of rechargeables.

Get a decent battery charger to make the most of the batteries.

I have a PowerEx C9000 which is the best available. There are some cheaper ones the 700 model such as BL-700 made by many different manufacturers and a 1000 model. Voltcraft use the same designs but in a variety of models.

I used to use rechargeables but was very disappointed with their performnance but I found that Amazon were supplying AA batteries at £5.00 for 20. So far they appear to be very reliable.

home phones often use 550mah AAA batteries too.

I tried upgrading our phones to higher mah batteries but it was not a success. I don't know whether the dedicated base charger could actually supply enough umph to charge them past a certain point.

Reverting to new 550mah batteries and they work a treat once more.

I would also seek out LSD batteries - Uniross Hybrio or GP Recyko are OK too and abetter price than some equivalents .

NOT recommending these batteries but they do suggest they are directly compatible as AAA.

Is there any way of checking when batteries are no-longer any use.

I have hundreds for rechargeables - and no idea which are still in good nick.
