"Great product easy install"
"Looks like a good battery at a good price. All seems to work fine in my van."
"Well priced AGM battery. Came almost fully charged (13. 2V). Comes with an Owners manual also which sets capacity and charge details. Mass of the battery indicates that it will meet same specifications (load) as the previous one. Only time will tell how it lasts. Old battery photo attached. - slightly lower AH."
"Forfilled a need at the right price and very convenient"
"Perfect for my setup"
"Battery works well"
"Replaced my old 100ah AGMs' in the caravan. These 135ah fitted perfectly & weighed a couple of kgs less than the old ones. Have connected to a trickle charge solar panel to keep topped up ready for the next trip. Delivery was around 4-5 days, great."
"I have four of these batteries to run the "house" on my yacht. Thats all internal electrical. They have lasted well and the company shipped directly to me when they needed replacement"
"Very happy ,quick delivery working well"
