GOOD REPLACEMENT
Arrived before schedule. This battery was a replacement for my Halfords Powerpack 200 that i have had over 10 years. One thing to note the battery i received did not come with upright tags (as shown in Amazon picture) but screw holes built into the battery. It was not so difficult to adapt, but just beware when ordering. I would suggest a full charge before using.

Wrong Connectors - Pic is wrong
Battery’s size and performance are unknown at the moment. The original battery that is in the Viking T5 has a 12v-17ah with 16-5 lugs as connectors. This does work in it, but is a pain to get new fittings. Also quite difficult to put the battery cover back on. If you’re after a battery to just replace without doing alterations don’t bother with this. Look elsewhere

Perfect for Lawnmower
I bought this as replacement battery for my ride on lawnmower. It was not the same dimensions as the original - same length but narrower width so still fitted in the space no problem. Works great.

Assault and battery........
Bought this to revive one of those "Jump packs" that i bought for a fiver and it worked for a while but when i looked t the cost of a new one when the battery and clips got past their best, this battery with a new set of clips was the obvious choice. Holds it's charge well and is now powerful enough (courtesy of the bigger capacity Vs the standard 17Ah battery in the jump pack) to kick my classic Rover 2.7 V6 over when i've not used for a while. Being disabled i also use a mobility scooter (Granny Go-kart :D ) and when the batteries on that eventually snuff it, i'll almost certainly use a pair of these for the extra capacity etc.
