Zhongneng Chengyu Power Co., Ltd is a manufacturer of various VRLA battery, like lead acid battery, deep cycle AGM battery, deep cycle gel battery, OPzV battery and ect.Deep Cycle Gel batteries utilise gel electrolyte technology, which holds the battery plates securely in an immobilised gel. This design makes Deep Cycle Gel batteries extremely robust and resistant to spillage if accidentally tipped upside-down.The range is completely maintenance free, requiring no topping-up of liquid electrolyte, whilst the valve-regulated sealed design enables installation in hard to reach locations.

Product Details of deep cycle battery
1.Gelled electrolyte made by mixing sulfuric acid with silica fume.
2.The electrolyte is gel like ,immobile and does not leak ,enabling
uniform reaction of each part of the plate .
3.High rate discharge performance due to tight assembly technology
4.Strong heat dissipation and wide operating temperature range
5.Avoid acid mist being separated out , environment friendliness
6.Efficient venting system release excessive gas automatically
1.Material Grade A original lead , purity near 100%
2.Production time make lead plate ourself , delivery time about one week
3.Price We are big factory and prodce lead plate instead of purchasing, so can control the cost ,quality and production time easily.
4.Technology advanced welding machine ,not easy shourt-circuit ,ensure batteries long life.
5.Quality All batteries should be tested 5 times before packing to ensure quality OK.
6.Package professional workers ; Non fumigation pallets can be exported to all countries .
7.Low self-dischargeThe use of analytically pure sulphuric acid electrolyte and reasonable arrangement of special additives can effectively reduce the self-discharge speed of the batteries.
8.High safetyThe efficient safety valve made of imported rubber is durable, ageing resistant and corrosion resistant that can effectively ensure the safety of internal pressure of the products in use.
9.Economical and practical The extremely high performance, long service life and low maintenance combined to make Tree batteries as
10.Maintenance free As it is value-regulated .sealed and glass mat is utilized .acid GEL is trapped inside . so refilling is not needed and is leak proof.
Quality Control System
Chengyu power applies the most advanced equipments and continual improved artworks to organize the production process. The QC department consists of IQC,IPQC, QA, QE, OQC, laboratory and testing subsidiaries’ which strictly meets ISO9001 quality system requirements from in-house material to batteries out warehouse to make sure the products are under the strict audit in the whole process.
The defective rate is below 0.1%. Meanwhile, Chengyu power take analytical pure material to make sure the batteries with high quality, long life, low self discharge advantages.
Q1: Are you factory?
A1:Yes, our factory is located in Nanjing, Jiangsu Province.
Q2: What’s your payment terms?
A2:We accepted almost all payment terms,like T/T,L/C,Paypal,Western Union
Q3: OEM Service
A3: If your quantities reached 100PCS , We also can printing your LOGO on Battery carton.
Q4: Warranty process.
A4: We can provide 1 ~ 5 years different warranty.
Q5:How long is your delivery time?
A5:Normally,the whole production cycle need 30 days from material to finished products,but we can send goods within 7 days if we have stock in our warehouse.
Q6: Why our price competitive ?
A6: Because the lead plate , battery case etc , all the battery accessories all from our produce.
Q6. How should a battery be stored?
A6.Always store your batteries FULLY CHARGED.
Check all batteries once a month and recharge as needed.
Wet batteries can hold their charge up to 3 months.
Sealed batteries can hold a charge for up to 6 months.
When storing a chair or scooter for more than 2 weeks, charge the batteries and then disconnect them.
Avoid hot and cold extremes when storing.
