25.2V 3.5Ah Li-ion Replacement Battery for Shark XBATR725SLEU, Compatible with Shark IZ400UK, IZ400UKT, IZ420UKT Cordless Vacuum Cleaners, Black

This shark battery from Amazon is half the price and works perfectly well. How long it lasts will only tell. The original lasted 3 years so we will see.

It works, and charged to 100%

It works fine. Delivery man did not come at 11.30 am. Stayed in all day. He came at 6.30 pm .

Didn't notice an issue with this battery until it came time to charge it, whereupon it just wouldn't take a charge at all (even using the AL1830V charger). So worse than a 1.5Ah battery it was bought to replace, and much more expensive. Since I didn't notice its fault until after the 30 days Amazon give you, I'm stuck hoping for refund/replacement from the manufacturer. Will update if they solve the problem, but until then can only advise to avoid this and stick with the proper Bosch ones. Update: received a full refund from seller. The item is junk still, and I have serious doubts about its stated capacity, having ordered a proper Bosch 4Ah battery instead. I weighed the junk one and the Bosch one. Junk one was lighter by 16 grammes, despite claiming to have 20% more energy storage. I'm sure the plastic they use isn't as heavy-duty, but even so that seems iffy.

I took a punt having read a few review about other check batteries, some saying they did hold on right etc. However I was pleasantly surprised at the quality for the cost, and it clicks on fine.

Poor quality. 5 months later, charged from 0 to 100% around 10 times, it no longer charges properly. Now I need to buy a new battery to replace it.

This battery works well but keeps falling out when hoovering.

It fits my shark IZ400UKTBK. Charges well. Is a good replacement or spare.

A bateria não tem qualquer carga e não aceitou carga. Bateria avariada. Está pronta para devolução
