Molisau 5.5Ah 18V Replacement Battery, Compatible with Bosch Battery PBA PSB PSR Gloria 18V Battery Gardena 18V System（But NOT Compatible with Bosch Unlimited Vacuum Cleaner）

🔋 This is somewhat of a mixed review, unfortunately. This battery is a replacement for some Bosch and Gardenia appliances, and those two brands generally speak out for quality, at least in my experience. My photos have a Gardenia battery that is on the compatibility list, which fits a garden strimmer. I expected, therefore, that this battery would fit perfectly.🔋 On the plus side, the battery is chunky, and taking it apart reveals that it contains 10 batteries that are 18650s, which is expected given the size of the pack. This results in 18 volts and about 5,000 mAh. Without disassembling the battery further, I can see that the charge circuitry is relatively sparse, with a 1051 charge protection chip visible on the circuit board, and that’s about it. All of the rest is achieved by discrete SMD components. The board soldering is well done, although one of the wire connections is serviceable but not the best.🔋 The casing looks a little cheap, with the two sides not completely identical. It is untextured compared to my original battery, and the retention catch is not quite as positive compared to the original. Looking at the terminals, I can see that they are not precisely aligned either. The biggest problem is that the battery does not fit very well at all, either to the strimmer or to the battery changer. It just won’t slide in all the way and lock successfully without a lot of effort. It kept falling out of the strimmer. I did manage to jam it onto the charger, and it did then charge up.🔋 I used the strimmer with the large battery jammed into the socket, and it took some effort to get it to stay in there. With the battery in place, it did work, and the strimmer was fine. It was really no different from the smaller-capacity battery. I usually achieve garden strimming well within the capacity of the smaller battery, and sometimes if I don’t recharge the battery after each session, it can run out. I can therefore see the point of having a larger battery, and certainly for power tools with higher energy demands and run times. However, for this strimmer, I can’t really see the point of needing a larger capacity. It also adds to the weight as well. Sometimes battery size isn't everything.🔋 In summary, I had high expectations of this battery to give me extended use of the strimmer in the garden, but the practicality and reality of a cheap-looking replacement was disappointing. It's not exactly a cheap price either, and I think that I would prefer to pay a little extra for an original 4Ah that fits perfectly. I really dislike giving a review where I struggle to find much positive to say for balance, but that’s just the reality with this battery. ❌

Good quality and cheaper than lower capacity ones - seems to charge quickly, and costs less than 2.5Ah versions, but with maybe double the capacity / use time for the same appliance. Works well with our 18V Bosch strimmer.
