3.7V 500mAh 902030 Polymer Lithium Battery Rechargeable for Consumer Electronics Toys LED Lights Bluetooth Speakers PH2.0 Plug
What our readings say: 3 of the 7 reading-days a verdict needs, and none in the last 7 days.
Seller lists it at $16.95 — a claimed saving of $8.48. AliExpress does not verify that figure, and 36.6% of the listings we track make a claim in the same 50-59% range, so on its own it means very little.

How this compares to everything else we track
We show 11,186 products, one per title, in Electronics. At $8.47, it sits above the middle of that category, which is $5.99 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 50% off. So do 55,047 other products we track — 36.6% of our whole catalogue claims a discount in the 50-59% band. At that frequency the figure is a listing convention rather than a signal. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.
AliExpress reports 407 orders for it. For comparison, the median listing we track in Electronics reports 116 — though a category holds very different kinds of thing, so read that as scale rather than as a ranking. Order counts come from AliExpress and are not a claim about price.
We have recorded this product’s price on 3 separate days since 2026-10-03, and it has not moved once. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.
If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
