content: I've got an old Nokia C2-01 phone and the original battery doesn't last 2 days in standby so I've to charge it every day. I'd like to get a battery as good as the original one. My concern is to get a new but "old" Li-ion battery, I mean a battery built many years ago and then stored therefore now its quality is quite bad.The original battery code is BL-5C and you can see some specshere. I'd be perfect if I got a brand new battery with "real" 1050mAh as the original one at its time.I pointed to thisduracellbecause its feedbacks are good (note: it's available @ my local amazon) but there're few ones that say it lasts just one day. The sense is... it will be a bet, imho.I just want to to ask you if you can tell me a "safe" place on the web where to buy a li-ion battery for an old phone that is good for sure.

content: I've been using a rock solid nokia 6021 until its original BL-5B battery lasted only 1-2 days and then I bought a compatible "blue star" 1000mAh battery and... it lasted 1-2 days! From that experience I avoid "4$" batteries. Duracell is a well known worldwide brand and my personal bet is that it's more reliable in general *but* I don't know if it continues to produce these battery for old device nowadays or these batteries were built many years ago and now are very old.Due to that I asked here for your suggestions, I know you're very skilled and experienced.

content: You at least need to buy a battery with a realistic capacity claimed. All of the batteries with exaggerated capacity are guaranteed to be junk.

content: I bought a Duracell branded BL5C from CPC/Farnell in the UK in December 2020, which continues to perform well in my C2-01. CPC/Farnell no longer stock it, and the DuracellDirect web site lists it as "End of Life". The label on my battery includes the text "(c) 2019", so that may have been the last year of production.

content: Definitely your answer is that it's a bet, isn't it? There's no more any "safe/sure" place where to buy that, I mean there's no "serious" battery brand that builds these batteries right now. In the best case I'll get a duracell aged 3 years in quite good conditions in a warehouse, in the worst case I'll get a un-named battery from aliexpress that will last as long as the original today (1day).The original nokia is 1050mah and the duracell is 1100mah fromofficial specs. I wonder if the duracell is better than the nokia or not. Anyway let's say 1050mah is the "limit" that define difference between a real capacity and a fake one, should I trust only compatible batteries within this limit? @wraper This question is especially for youThis DYNASONIC(available @ my local amazon) is another battery with quite good feedbacks on amazon but there's no production year printed on so it's another bet, imho.EDITI'd wanto to ask you a question about an alternative solution here instead of opening a new thread in the right area because if the answer is no I'll avoid to open an useless thread.Is it somehow possible to easily fit a 2 wired 3.7V Li-po battery likethisto supply a mobile phone instead of its proper Li-ion battery?

content: Well, I'd say anything that claims 1200+ mAh is most likely fake. 1100 mAh should be ok from a reputable brand. Also dunno about Nokia but capacity can be rated differently, like minimal guaranteed or typical. In any case lower capacity does not mean it's real, just that it's less likely fake.

content: Got the duracell from amazon, the same one of @cbutlera. It lasts 5 full days with my light-average use so I'm quite satisfied. Just a curiosity: is it possible to see its production year? The battery has no label sticked on, just F2107P printed on its side.

content: I went through a similar situation recently ... My GPSlim 236 uses the same type of battery shape but mine was swelling so I wanted to replace it.I ended up buying a second hand basic entry level nokia with a smashed screen just for the battery .. photos of the battery looked fine. I think the one I got must have been stored for a while as it was 0v when I got it and took a bit of faffing around to get it to charge.The other option would be to buy a brand new entry level nokia just to harvest the battery.
