Need it for the CD-Bläher my son. Unfortunately, this child-friendly device requires 6 C batteries, with children and technology collects indeed a huge smorgasbord of batteries. The capacities seem to be tailored not exactly each other. Thus, if some batteries are empty, ie 0.8 V, others still have 1.15 V. I had there ever even better. In addition, the mass of the batteries are not quite the same, for example, has a 80 g, the other 79th But I lament here at a high level. For the price they are very good. The charging time for 1 A is 4-5 h, at least initially, likely to the vote with the 4.5 Ah, although of course comes out slightly less power due to the Faraday efficiency than goes in. Anyway, they are much better than my last Tensai with 4 Ah, even if the are not bad.
Overall, I would still recommend it to anyone, even to dispense with devices with battery sizes of C and D and if necessary to use adapter for AA batteries if you do not mind, that something must be often loaded one. AA batteries are the price-ampere-hours ratio simply cheaper. A 3 times as heavy battery provides only double capacity.
