Rechargable Batteries
Every year all over the world, many thingd are bougth that are useful in household or in office purpose.One such commodity is batteries billions are bought used and thrown out. Households generally use disposable alkaline, rechargeable, and car batteries.Technology is te back bone of every electronic that is up and running.The demand for batteries can be traced largely to the rapid increase in cordless, portable products such as cellular phones, video cameras, laptop computers, and battery-powered tools and toys…
Because many batteries contain toxic constituents such as mercury and cadmium, they pose a potential threat to human health and the environment when improperly disposed. Though batteries generally make up only a tiny portion of municipal solid waste less than 1 percent.When this waste is incinerated or disposed of in landfills, under certain improper management scenarios, these toxics can be released into the environment.
Over the past decade, the battery industry, partly in response to public concerns and legislation, has played an active role in finding solutions to these problems. Industry efforts have touched on every stage of the product life cycle.Some battery manufacturers are redesigning their products to reduce or eliminate the use of toxic constituents. But redesigning them is not doing any benefits in the long run.Thus the demand of the rechargable batteries seems to grow eversince.
Rechargeable batteries currently are used for lower power applications such as automobile starters, portable consumer devices, tools, and uninterruptible power supplies. Emerging applications in hybrid vehicles and electric vehicles are driving the technology to improve cost, reduce weight, and increase lifetime. Future applications are proposed to use rechargeable batteries for load leveling, where they would store baseline electric power for use during peak load periods, and for renewable energy uses, such as storing power generated from photovoltaic arrays during the day to be used at night.
The energy used to charge rechargeable batteries mostly comes from mains electricity using an adapter unit. It can be wired or wireless.Reverse charging, which damages batteries, is when a rechargeable battery is recharged with its polarity reversed. When a battery is incorrectly inserted into a charger. When multiple batteries are used in series in a device. When one battery completely discharges ahead of the rest, the other batteries in series may force the discharged battery to discharge to below zero voltage.Be cautious of this to prevent a health hazard.

Thanks – all valid suggestions
QUAD Encoders on feed motor shaft – unfortunately does not give closed-loop feedback on what the wire is actally doing. slip etc is not accounted for.
V-groove – already in the unit you are watching.
2 Idlers – not sure how that can reduce slip?
Gears always help – very true. Add cost & complexity – and reduce speed, but always worth considering to get the result.
Power supply – I originally used a small battery bank with a constant charger – but after about 20 minutes operation the voltage began to drop to [...]
