If you are a keen battery buyer, you would have noticed our new batteries, well not new but renewed.

The legal bit....
We had a issue with the payment system where by it was costing us money when people changed there mind, usually when people had batteries that they had to wait for and never read this fact and google was promising delivery in 2 days. It was not a small amount either.

As you may know as a returning customer,  we have made the adjustment with a "plug in" to the shop which adjusts the prices depending how you pay. We had to them update the terms and conditions to reflect that the payment administration costs were a separate service. but we have also now had to align the "cash prices" as they were reduced from the "standard price" shown on the website.

Now for the batteries

RenewSolar last year put to tender the supply of battery packs, we do this now and them to ensure completion and lower the cost of batteries. The tenders are not just lowering prices but retaining quality and having what YOU want at the best price possible.
This means that your battery selection gets updated and we slot them into 3 categories, Budget, Mid range and top.

Budget would be your mid range batteries available from reputable suppliers. The idea here for us, is to cut as many corners as possible while retaining safety and functionality. all the frills are not there, but you get the essentials, capacity and reliability.

Our Mid range batteries are what you would find as the flag ship batteries from other companies. These have blue tooth wifi, brand names hardware and a little bit more on quality here as well as warranty and support.

The top range have more. Here we look at flag ship operation and over engineered solutions. A better managed battery and system which design and conformance as well as performance are considered. So you get extra. There would be higher capacity than stated, the setting will prolong the battery life and there is more hardware in the battery to ensure its operation and life span.

Warranty.
Budget battery will be basic, it will have 1 year manufacture warranty. no collect or return, and for faults past this period you may not be able to effect repair yourself, but you can send in hardware for repair and testing.

Mid range batteries often come with a  5 year warranty which includes capacity performance and collect and return service. Faults and testing are included in the warranty, but do check that they have the collect and return warranty as we have a bit of a wider range of batteries in the mid range section.

Top tier batteries come with a lot of support from us and the manufactures, we work together to ensure you don't have issues and can always rely on us both if you have any issues and questions for up to 10 years following your purchase.

No Warranty.
If you buy a battery that has no warranty, it does not mean you are buying at a big risk. RenewSolar is a ethical business; should your battery break or have an issue, you can contact us about it and you may find that you have a small easy, and cost effective repair. we offer diagnostic's and replacement parts as well as upgrades. and can fit them for you if required. This will be a charged service, but its wont be like taking a care to a garage 😉

Battery capacity.
All batteries should have the stated capacity as well our cells. should you find you do not, then contact us. Most of our battery supply chain offer a full refund. but before anyone says they capacity tested it and it was under, ensure that you know how to test and that you have calibrated testing equipment --- not some ebay / temu special.--

We do have test data and a lot of it when it comes to battery packs, they are pre tested by the manufacture and then tested before the build and then after. Cells are also matched in the process and so the likelihood that you have not got capacity is near zero. Budget tends to hit capacity, mid range is capacity and just over, and then premium is usually over capacity. in the premium battery range we may limit capacity in larger systems in order to retain life cycles of the battery, but you would still see the "stated capacity".

- Capacity drops
We are called out to test battery packs and problems from where fly by night solar companies install solar and batteries and then there are a lot of problems to fix. A common problem is a capacity drop.
And while I bash other companies, there are DIYers and special people who like to play around with settings and think they know best because they read on line...
The most common capacity fault is due to under charging or over charging. - Low voltage high current.

The second most fault is crap batteries and the wrong size.
Over using the batteries due to them being too small. reducing the life of the battery.
There are many "brands" that have got hyped, but are in fact terrible batteries, most people are now finding out how bad they were to listen to the "internet people".

There is of course cheap crap, which are usually ebay special or some one buying rubbish and selling it on ebay.  They often have used cells or faulty cells that work for a short time and as they are thrown together with a cheap BMS that cannot cope with the "problems" meaning that they have a short life.

There is of course a developed fault that can occur - balancer, lead circuit or even internal cell issues, they are fairly rare, but when shipping, they can happen.

In short.
All our batteries are a good quality and we price them fairly. we have a decent warranty process and we test and check everything. Problems let us know. You will wait around 30 days for a battery. buy with direct transfer and it cost less.
