It's not even close to 5600mah. I bought it to replace 3000mah 1 year old flood lights battery. Had two lights next to each other one with this battery and one with factory....and they both drained at the same time. So this battary has aprox half capacity from advertised.

    • Versatile Connectors and Good Value, Despite Overstated Capacity

These lithium-ion packs are a convenient solution for DIY electronics, Bluetooth speakers, or RC repairs. They are physically well-constructed and offer a level of out-of-the-box versatility that is hard to find in standard battery packs. Design & Versatility The standout feature here is the wiring. These packs include both SM2.0 and PH2.0 connectors. Having both options pre-installed makes them incredibly versatile for a wide range of devices without needing to break out the soldering iron or crimping tools just to swap a plug. Capacity Testing As is common with many batteries on the market today, the capacity specifications are unfortunately overinflated. Claimed Capacity: 5600mAh Measured Capacity: 4240mAh In a professional testing environment, these packs delivered roughly 75% of their stated capacity. While falling short of the 5600mAh claim is a negative, a 4240mAh 18650-style pack is still a very usable amount of energy for most small electronics and DIY projects. Value Proposition Despite the capacity gap, the price-to-performance ratio remains strong. Getting two well-assembled packs with dual connector options for this price is a great deal. If you manage your expectations regarding the total runtime and treat these as ~4200mAh units, they are a solid buy. Pros Dual Connectors: SM2.0 and PH2.0 plugs make them ready for almost any hobbyist application. Well-Assembled: The shrink-wrap and lead wires feel durable and secure. Price: Excellent value for a two-pack, even considering the actual capacity. Cons Overstated Specs: Measured capacity is significantly lower than the 5600mAh claim. Final Verdict: 4/5 Stars If you need a reliable, plug-and-play battery pack for a DIY project and aren't strictly dependent on that 5600mAh number, these are an excellent choice. The versatility of the connectors alone makes them worth the price. ... show more
