Battery pack PBA 18V 4.0Ah W-C (18 volt System, 4.0Ah, in Carton Packaging)

Have had the Bosch Unlimited 7 vacuum cleaner for just over a month now (great vac) and it came with 2 3.0 Ah batteries. Perfectly fine, and they can be readily swapped to complete a full clean of the house, on Eco mode. They recharge in about 40 mins - which is fine too. However - the extra 1.0 Ah means that a mid-clean battery swap is no longer required (for the daily clean) and leaves the 3 Ah batteries in reserve for a deep clean and the additional (maybe unexpected) things like the cars or helping out old relatives. No more monitoring of the charge LEDs. Daily clean can now complete in Auto mode with one bar left.. Note that this battery is about 25% heavier than the smaller varieties (and about 20% larger), so if you already struggle with the total appliance weight then I recommend that you put up with the slight inconvenience of swapping batteries. Also, the recharge time is obviously 30% longer. Is it worth the cost? Well - that's subjective, and dependent on whether you already have appliances that can share the battery. I don't - all my heavy battery stuff is Makita (and won't be changing). BUT - yes - I'm happy with the purchase.

Got this one as a spare for my wireless Bosch vacuum cleaner and it perfect for the job. It can be used across all other Bosch wireless tools so it's good fit for the maintenance kit.

Great power, long life to be expected. But on receipt, I found it did not fit my existing charger. Solution was to buy a strimmer with a small battery pack and - fortunately - a different charger which fits all these Bosch batteries.

Large capacity battery for Bosch 18v appliances. Works fine with the chargers I have, for example, the AL 1830. It’s going to be very useful for those tools which I use for extended periods like my hedge trimmer. I’ve checked it with 3 or 4 devices like a sander and jig-saw, all fine. Battery has a useful battery check button so you can easily check the state of charge. Definitely worth paying the extra cost for this more up to date battery.

It was a present for my son he was very pleased with his present

Wow, lots of power! I bought this so supplement my Bosch tools with a longer-lasting power source, and this delivers! I used the Bosch extendable hedge trimmer to trim very large hedges, took me a couple of hours, and this battery still had lots of juice left when finished- for use with other tools! Slightly pricey but a good addition to the Bosch battery-powered tool set. Make sure this is the correct battery for your tools as although Bosch have standardised a lot, there are still some tools that take different battery designs, particularly if they are a little bit older.

Lasts for ages

Typical Bosch quality and lasts a good while whilst powering my tools with ease. I expected nothing less.
