3-4 years ago, I bought a no-name battery or another vendor also for the SL1. The details were similar to this rechargeable battery, so overheating protection, overcharge protection and short circuit protection. Now even this replacement battery slowly lost power, I opted for this new replacement battery. When removing the old spare batteries immediately noticed that this is fully inflated, so nothing with overcharge protection. The battery was so firmly attached to the phone, that I was worried on the phone right with destroying when removed. Whether this new replacement battery now actually good for more, as the old one, will probably have to show only. So far, he has relatively quickly (1,5-2h) fully charged. However, As for the one star deduction, unfortunately I had to realize that, contrary to the indication 'new battery of the latest production and always plenty in stock, "which should probably mean the frequent handling of these batteries and thus always absolute latest production, the supplied battery a production date from before about 1 year has (lt. stickers). To ensure that this battery is not new anymore and from the latest production, but old stocks. Should this affect the performance and durability, I'll probably order this battery with this provider ever again. I also doubt that actually every month to be bought new batteries and then sold off again, rather a huge post will probably shopped and only then sold off for months or years, if you follow the manufacturer date. Therefore, I have to deduct a star, though it basically even is a misrepresentation in the article and thus have to give an even lower rating. I now take the phone to the fully charged battery pack into operation and this should be over-discharged in the next few 1-2Tagen in standby mode without phone calls, he goes back because of defective goods.
Supplementary Feedback: At 14.1 as written fully charged, today at 18.1 (4days!) Pure standby time, without any use of the phone, began signaling for weak battery in. This acoustic signaling that the battery needs to be charged soon took less than 5 min and the battery indicator was empty. With the old battery performance was still a few hours and with the original battery of the phone even 24h. Since fresh batteries three-four times must be loaded before they reach their full capacity, I'll be watching the next, but it's a pretty bad sign that after such a short time, the initial charge is completely discharged and especially the battery indicator yesterday at 2/3 full status and this has completely stopped in my presence just within just three times signaling. This speaks not of particularly good cells wenns remain here, but more about it soon.
