Rated 1 out of 5 by from Great quality battery, doesn't include necessities I've already purchased three of the non-rechargeable battery packs (88000, and they work great!), but I wanted something that would be more convenient to recharge (So I don't have to remove it from my model each time to replace the batteries). Pros: - It did seem to come pre-charged, though I don't know how much - Definitely more powerful than the 88000 - The 7 phase power dial is really useful - It may be more expensive than the 88000, but in the long run it will be worth it as you won't need to purchase more AAA batteries Cons: - The LED's are in different spots from the 88000 (See pics), which make it annoying to see it's current status on sets - NO CHARGER (Continued below... ) I design custom trains for my collection and I'm always looking for ways to improve them, and this battery is a must for anyone who needs just that. (Continued:) I'd love to give the battery itself a full 10/10 as it stands tall with Lego's stamp of quality, but then a 0/10 for how poorly it was listed on this site, from the sheer lack of information, to the missing but simple necessity: a power supply. The description for the 8878 Battery made it sound like the power supply wasn't needed (Either included or was a common voltage), so I figured I'd have one at home or would be able to buy one locally and save money on shipping: that didn't work. The battery requires an odd voltage wall charger of 10v 700ma, which wasn't listed on this site... I didn't have one, no store locally had one, and the final annoyance with this whole ordeal, was on the instructions: as it ACTUALLY STATES "Only use an original LEGO transformer to recharge the battery"... I have never been more disappointed with a purchase from the Lego site in my entire life, I should have read the reviews... I would have still bought this item if it was $20 more and included the charger, now it will be twice that and more to order it... The entire product (8878) is essentially useless until you buy the wall charger for it, which is ALREADY overpriced for a wall charger. It's going to be a long while before I can order the wall charger, and all that time I won't even be able to use this expensive battery... I don't like writing negative reviews, believe me, I am writing this because I want Lego to improve, to do even better. I've been a builder my entire life and will continue to promote Lego as the best toy builder in the world!

Rated 2 out of 5 by from Incomplete Product We ordered this rechargeable battery because we needed to be able to adjust the speed and we are pleased with that aspect of the battery. HOWEVER, it does not come with a charger! And not only that, you HAVE to use the correct charger from Lego...which is an extra $30...that comes to $80 in order to use this battery pack. This is the first time we've been disappointed by a product from Lego. It came charged so we got to play with it for a bit, but we won't be able to recharge it until we order the charger which will be awhile so now the battery is useless.

Rated 1 out of 5 by from Charger sold separately! I, like others, assumed a $50(!) rechargeable battery would come with the means to recharge it. The description needs to add the words "(not included)" right after the statement saying it can only be charged with the LEGO transformer. Though honestly, I'm not sure that would have helped me avoid this mistake as I bought the item based on the title and it showing up as a recommended item when I added other power functions to my bag. The power functions needed to motorized my LEGO train were already getting pricey and I'm now considering returning them all. This battery box is certainly getting returned as I'll just use rechargeable AA batteries in the battery box holder if I decide to keep the power functions. (And I'll still never have to buy AA batteries again!) I suspect if you already have the transformer to recharge this, it could be a good purchase depending on how many recharging cycles this battery gets. Others will have to speak to that, though.

Rated 4 out of 5 by from Good for long trains I bought my 3th rechargeable battery box for one of my Lego trains. I prefer the rechargeable one above the AAA-battery box because the power is higher which is good for a long train. Otherwise you don't have to take out the battery box of the train each time to change the AAA-batteries. You have only leave a hole where can connect the DC-adapter. The price is high but it gives a lot of power and the train can run a long time.
