Technical Data

Features 2 volt 500ah gel battery

From material selection to delivery We master the entire production process and strictly control the quality of each component to ensure quality.
	Purest lead ingot Lead ingot: Pb-1 Lead content ≥ 99.994%
Electrolyte The electrolyte of Casisolar’s 2 Volt 500ah Valve Regulated Lead Acid Gel Battery use patented formula and the main component of nano-gelled imported from German, which has the consistency and appearance of petroleum jelly. Nano gel helps batteries have stable performance at high and low temperature and 5 years longer than AGM battery.
	Plate The plate of Casisolar’s 2 Volt 500ah Valve Regulated Lead Acid Gel Battery is usually thicker, pasted flat type with patent formula ensure stronger ability to recover from deep discharging. This also do a great help of batteries service for two years longer.
Grid Casisolar’s 2 Volt 500ah Valve Regulated Lead Acid Gel Battery use special design of radioactive grid structure, lead-tin alloy helps greater ability of anti-corrosion. This help our batteries service two years longer and other gel. Batteries..
	Separator You will always find that the separator in our batteries are in double quantity, the material should be updated long and superfine fiber separator with higher absorptive and lower resistance, which helps batteries service longer.

NOTE

· We recommend only using consistent battery types. DO NOT mix new and used batteries together as it will reduce overall performance .

· To avoid cycle-life shortening, we recommend not discharging the battery below 40%.

· It is highly recommended to use a battery balancer to extend the battery service life when multiple batteries are connected in series and/or in parallel.

· We highly recommend installing the battery upright. It is allowed to install the battery on its side only if there are special reasons for doing so.

DO NOT install the battery upside down.

FAQ

1. How many life cycles does this GEL battery have?

This CASISolar 2 Volt 500ah Valve Regulated Lead Acid Gel Battery enables more than 1000 charge/discharge cycles at 50% DOD (Depth of Discharge) in cyclic applications.

2. Will the battery come with the terminals? And if not, what's the size of the connector terminals?

Yes, it comes with two copper screw terminals. The size is M8 x 1.25 x 16 mm.

3. Can your gel battery be charged by e-bike charger with AC?

Depends. The charging current should be less than 0.25C10. For example 25A is the max for 12V100AH battery. So only chargers within the permissible voltage range can be used.

4. How to properly store the Gel battery?

Store it in a dry and cool place at -30℃~50℃. Charge it to full before delivery and recharge after three months.

5. How can I fix this GEL battery if I over discharged it?

It can be restored to normal voltage and continues to operate normally through low-current charging. Please note that frequent over-discharge may cause irreversible damage to the battery's life. To avoid cycle-life shortening, we recommend not discharging the battery below 40%. You can contact us to make sure your system working in balance, info@casisolar.com.

Together with our customers and suppliers, we have been partners in solar battery industry for 12 years and have supplied over 20 kinds of patent solar systems for home and abroad.

In 2008, we established FairylandSolar^TM and won our first solar home system project--“GoldSun” project for whole Shaanxi province which was a famous big project appointed by Chinese government. During 3 years installation, we were always moved a lot when people showed true smile when lighting their home. They should carry a heavy battery and walk hours home, so aftersales is so difficult that pushes us to supply high quality products with long lifetime. We invested gel battery production line with a 50 staff team who has 20 years production experience for AGM battery. For the enough good quality and reasonable price, we becomes a stable supplier for solar projects, OEM for them.

In 2018, as the rapid development of lithium battery, we established CASISOLAR^TM that started a team only for packing lithium batteries. During the past 3years, we found the wide difference between price and products. As government promotes “ giving retied battery a second life” , some make a profit in troubled situation, providing retired cells for solar making great lost in a long term or even has personal safety hazard.

So in CASISOLAR, we don’t think it is 100% safe to use retired battery cells. We only accept cells at Great A with 5 years more warranty. We didn’t grow up quickly but we harvest every customer we have cooperated. We always enjoy and appreciate troubles met during every cooperation, and give great enthusiasm and confidence.

Our mission is to provide solar energy at low cost over a long lifetime.
