Hello Mr Oladokun,

Do your paints need primer? I see that Chemstar Industries Nigeria Limited do not have primers for their building paints. Please let me know if primer is needed. Also, kindly answer the following questions:
- Which paint to choose for inside rooms?
- Which paints are for the outside walls?

Best Regards

Guys, please help with my Murano. We swapped Maxima engine & gearbox into it, but since then it can not rev past 3000 rpm and it does slow acceleration (slipping). The gears also do kicks in D & R.

Most of you guys just talk about inverters, meanwhile you were actually talking about UPS (uninterruptible power supply). Converters convert AC voltage source into an DC voltage output. The inverter does the opposite, inverting a DC voltage source into an AC output. What most of you guys have in your homes are UPS (a combination of the two) which takes in the NEPA/PHCN distorted 230V and gives you a stabilized voltage of 230V at the same time keeping you online (powered up) when NEPA/PHCN packs up (rationalized).

The UPS incorporates charge principles in the same system as well as battery(ies). Batteries used in UPS devices are supposed to be deep cycled batteries allowing for shallow depletion with no problems but with long (slow charging process), but this is not always the case, because deep cycled batteries are expensive and hence make the UPS more expensive and vulnerable to competitive products in terms of affordability. Due to this, most UPS sold in Nigeria will not have deep cycled batteries.

Going from above description, most UPS on sale in Nigeria have batteries that are charged quickly but deplete same way - quickly. When these type of batteries deplete too quick, too soon and frequently, they loose their charging capability and therefore can no longer be charged.

Unfortunately, there are too few people (sellers of these devices) in Nigeria that really understand the holistic of battery technology. Most of them have no time to do the required knowledge research, they are more preoccupied with the return on their business investment.

Anyone of you that may be seriously interested in real working renewable technology can let me know. I am an electrical engineer and I live and work in Zurich, Switzerland.
